+Introduction
+************
+
+ATF uses the GNU Automake, GNU Autoconf and GNU Libtool utilities as its
+build system.  These are used only when compiling the application from the
+source code package.  If you want to install ATF from a binary package, you
+do not need to read this document.
+
+For the impatient:
+
+  $ ./configure
+  $ make
+  Gain root privileges
+  # make install
+  Drop root privileges
+  $ make installcheck
+
+Or alternatively, install as a regular user into your home directory:
+
+  $ ./configure --prefix ~/local
+  $ make
+  $ make install
+  $ make installcheck
+
+
+Dependencies
+************
+
+To build and use ATF successfully you need:
+
+* A standards-compliant C/C++ complier.  For example, GNU GCC 2.95 will not
+  work.
+
+* A POSIX shell interpreter.
+
+* A make(1) utility.
+
+If you are building ATF from the code on the repository, you will also need
+the following tools.  The versions listed here are the ones used to build
+the files bundled in the last formal release, but these are not strictly
+required.  Newer ones will most likely work and, maybe, some slightly older
+ones:
+
+* GNU autoconf 2.68
+
+* GNU automake 1.11.3
+
+* GNU libtool 2.4.2
+
+
+Regenerating the build system
+*****************************
+
+If you are building ATF from code extracted from the repository, you must
+first regenerate the files used by the build system.  You will also need to
+do this if you modify configure.ac, Makefile.am or any of the other build
+system files.  To do this, simply run:
+
+  $ autoreconf -i -s
+
+For formal releases, no extra steps are needed.
+
+
+General build procedure
+***********************
+
+To build and install the source package, you must follow these steps:
+
+1. Configure the sources to adapt to your operating system.  This is done
+   using the 'configure' script located on the sources' top directory,
+   and it is usually invoked without arguments unless you want to change
+   the installation prefix.  More details on this procedure are given on a
+   later section.
+
+2. Build the sources to generate the binaries and scripts.  Simply run
+   'make' on the sources' top directory after configuring them.  No
+   problems should arise.
+
+3. Install the program by running 'make install'.  You may need to become
+   root to issue this step.
+
+4. Issue any manual installation steps that may be required.  These are
+   described later in their own section.
+
+5. Check that the installed programs work by running 'make installcheck'.
+   You do not need to be root to do this, even though some checks will not
+   be run otherwise.
+
+
+Configuration flags
+*******************
+
+The most common, standard flags given to 'configure' are:
+
+* --prefix=directory
+  Possible values: Any path
+  Default: /usr/local
+
+  Specifies where the program (binaries and all associated files) will
+  be installed.
+
+* --sysconfdir=directory
+  Possible values: Any path
+  Default: /usr/local/etc
+
+  Specifies where the installed programs will look for configuration files.
+  '/atf' will be appended to the given path unless ATF_CONFSUBDIR is
+  redefined as explained later on.
+
+* --help
+  Shows information about all available flags and exits immediately,
+  without running any configuration tasks.
+
+The following environment variables are specific to ATF's 'configure'
+script:
+
+* ATF_BUILD_CC
+  Possible values: empty, a absolute or relative path to a C compiler.
+  Default: the value of CC as detected by the configure script.
+
+  Specifies the C compiler that ATF will use at run time whenever the
+  build-time-specific checks are used.
+
+* ATF_BUILD_CFLAGS
+  Possible values: empty, a list of valid C compiler flags.
+  Default: the value of CFLAGS as detected by the configure script.
+
+  Specifies the C compiler flags that ATF will use at run time whenever the
+  build-time-specific checks are used.
+
+* ATF_BUILD_CPP
+  Possible values: empty, a absolute or relative path to a C/C++
+  preprocessor.
+  Default: the value of CPP as detected by the configure script.
+
+  Specifies the C/C++ preprocessor that ATF will use at run time whenever
+  the build-time-specific checks are used.
+
+* ATF_BUILD_CPPFLAGS
+  Possible values: empty, a list of valid C/C++ preprocessor flags.
+  Default: the value of CPPFLAGS as detected by the configure script.
+
+  Specifies the C/C++ preprocessor flags that ATF will use at run time
+  whenever the build-time-specific checks are used.
+
+* ATF_BUILD_CXX
+  Possible values: empty, a absolute or relative path to a C++ compiler.
+  Default: the value of CXX as detected by the configure script.
+
+  Specifies the C++ compiler that ATF will use at run time whenever the
+  build-time-specific checks are used.
+
+* ATF_BUILD_CXXFLAGS
+  Possible values: empty, a list of valid C++ compiler flags.
+  Default: the value of CXXFLAGS as detected by the configure script.
+
+  Specifies the C++ compiler flags that ATF will use at run time whenever
+  the build-time-specific checks are used.
+
+* ATF_CONFSUBDIR
+  Possible values: empty, a relative path.
+  Default: atf.
+
+  Specifies the subdirectory of the configuration directory (given by the
+  --sysconfdir argument) under which ATF will search for its configuration
+  files.
+
+* ATF_SHELL
+  Possible values: empty, absolute path to a POSIX shell interpreter.
+  Default: empty.
+
+  Specifies the POSIX shell interpreter that ATF will use at run time to
+  execute its scripts and the test programs written using the atf-sh
+  library.  If empty, the configure script will try to find a suitable
+  interpreter for you.
+
+* ATF_WORKDIR
+  Possible values: empty, an absolute path.
+  Default: /tmp or /var/tmp, depending on availability.
+
+  Specifies the directory that ATF will use to place its temporary files
+  and work directories for test cases.  This is just a default and can be
+  overriden at run time.
+
+* GDB
+  Possible values: empty, absolute path to GNU GDB.
+  Default: empty.
+
+  Specifies the path to the GNU GDB binary that atf-run will use to gather
+  a stack trace of a crashing test program.  If empty, the configure script
+  will try to find a suitable binary for you.
+
+The following flags are specific to ATF's 'configure' script:
+
+* --enable-developer
+  Possible values: yes, no
+  Default: 'yes' in Git HEAD builds; 'no' in formal releases.
+
+  Enables several features useful for development, such as the inclusion
+  of debugging symbols in all objects or the enforcement of compilation
+  warnings.
+
+  The compiler will be executed with an exhaustive collection of warning
+  detection features regardless of the value of this flag.  However, such
+  warnings are only fatal when --enable-developer is 'yes'.
+
+* --enable-tools
+  Possible values: yes, no
+  Default: no.
+
+  Enables the build of the deprecated atf-config, atf-report, atf-run
+  and atf-version tools.  atf-report and atf-run have been superseded by
+  Kyua, and atf-config and atf-version are unnecessary.
+
+
+Post-installation steps
+***********************
+
+After installing ATF, you have to register the DTDs it provides into the
+system-wide XML catalog.  See the comments at the top of the files in
+${datadir}/share/xml/atf to see the correct public identifiers.  This
+directory will typically be /usr/local/share/xml/atf or /usr/share/xml/atf.
+Failure to do so will lead to further errors when processing the XML files
+generated by atf-report.

+Major changes between releases                  Automated Testing Framework
+===========================================================================
+
+
+Changes in version 0.16
+***********************
+
+Experimental version released on July 10th, 2012.
+
+* Added a --enable-tools flag to configure to request the build of the
+  deprecated ATF tools, whose build is now disabled by default.  In order
+  to continue running tests, you should migrate to Kyua instead of enabling
+  the build of the deprecated tools.  The kyua-atf-compat package provides
+  transitional compatibility versions of atf-run and atf-report built on
+  top of Kyua.
+
+* Tweaked the ATF_TEST_CASE macro of atf-c++ so that the compiler can
+  detect defined but unused test cases.
+
+* PR bin/45859: Fixed some XSLT bugs that resulted in the tc-time and
+  tp-time XML tags leaking into the generated HTML file.  Also improved
+  the CSS file slightly to correct alignment and color issues with the
+  timestamps column.
+
+* Optimized atf-c++/macros.hpp so that GNU G++ consumes less memory during
+  compilation with GNU G++.
+
+* Flipped the default to building shared libraries for atf-c and atf-c++,
+  and started versioning them.  As a side-effect, this removes the
+  --enable-unstable-shared flag from configure that appears to not work any
+  more (under NetBSD).  Additionally, some distributions require the use of
+  shared libraries for proper dependency tracking (e.g. Fedora), so it is
+  better if we do the right versioning upstream.
+
+* Project hosting moved from an adhoc solution (custom web site and
+  Monotone repository) to Google Code (standard wiki and Git).  ATF now
+  lives in a subcomponent of the Kyua project.
+
+
+Changes in version 0.15
+***********************
+
+Experimental version released on January 16th, 2012.
+
+* Respect stdin in atf-check.  The previous release silenced stdin for any
+  processes spawned by atf, not only test programs, which caused breakage
+  in tests that pipe data through atf-check.
+
+* Performance improvements to atf-sh.
+
+* Enabled detection of unused parameters and variables in the code and
+  fixed all warnings.
+
+* Changed the behavior of "developer mode".  Compiler warnings are now
+  enabled unconditionally regardless of whether we are in developer mode or
+  not; developer mode is now only used to perform strict warning checks and
+  to enable assertions.  Additionally, developer mode is now only
+  automatically enabled when building from the repository, not for formal
+  releases.
+
+* Added new Autoconf M4 macros (ATF_ARG_WITH, ATF_CHECK_C and
+  ATF_CHECK_CXX) to provide a consistent way of defining a --with-arg flag
+  in configure scripts and detecting the presence of any of the ATF
+  bindings.  Note that ATF_CHECK_SH was already introduced in 0.14, but it
+  has now been modified to also honor --with-atf if instantiated.
+
+* Added timing support to atf-run / atf-report.
+
+* Added support for a 'require.memory' property, to specify the minimum
+  amount of physical memory needed by the test case to yield valid results.
+
+* PR bin/45690: Force an ISO-8859-1 encoding in the XML files generated by
+  atf-report so that invalid data in the output of test cases does not
+  mangle our report.
+
+
+Changes in version 0.14
+***********************
+
+Experimental version released on June 14th, 2011.
+
+* Added a pkg-config file for atf-sh and an aclocal file to ease the
+  detection of atf-sh from autoconf scripts.
+
+* Made the default test case body defined by atf_sh fail.  This is to
+  ensure that test cases are properly defined in test programs and helps
+  in catching typos in the names of the body functions.
+
+* PR bin/44882: Made atf-run connect the stdin of test cases to /dev/zero.
+  This provides more consistent results with "normal" execution (in
+  particular, when tests are executed detached from a terminal).
+
+* Made atf-run hardcode TZ=UTC for test cases.  It used to undefine TZ, but
+  that does not take into account that libc determines the current timezone
+  from a configuration file.
+
+* All test programs will now print a warning when they are not run through
+  atf-run(1) stating that this is unsupported and may deliver incorrect
+  results.
+
+* Added support for the 'require.files' test-case property.  This allows
+  test cases to specify installed files that must be present for the test
+  case to run.
+
+
+Changes in version 0.13
+***********************
+
+Experimental version released on March 31st, 2011.
+
+This is the first release after the creation of the Kyua project, a more
+modular and reliable replacement for ATF.  From now on, ATF will change to
+accomodate the transition to this new codebase, but ATF will still continue
+to see development in the short/medium term.  Check out the project page at
+http://code.google.com/p/kyua/ for more details.
+
+The changes in this release are:
+
+* Added support to run the tests with the Kyua runtime engine (kyua-cli), a
+  new package that aims to replace atf-run and atf-report.  The ATF tests
+  can be run with the new system by issuing a 'make installcheck-kyua' from
+  the top-level directory of the project (assuming the 'kyua' binary is
+  available during the configuration stage of ATF).
+
+* atf-run and atf-report are now in maintenance mode (but *not* deprecated
+  yet!).  Kyua already implements a new, much more reliable runtime engine
+  that provides similar features to these tools.  That said, it is not
+  complete yet so all development efforts should go towards it.
+
+* If GDB is installed, atf-run dumps the stack trace of crashing test
+  programs in an attempt to aid debugging.  Contributed by Antti Kantee.
+
+* Reverted default timeout change in previous release and reset its value
+  to 5 minutes.  This was causing several issues, specially when running
+  the existing NetBSD test suite in qemu.
+
+* Fixed the 'match' output checker in atf-check to properly validate the
+  last line of a file even if it does not have a newline.
+
+* Added the ATF_REQUIRE_IN and ATF_REQUIRE_NOT_IN macros to atf-c++ to
+  check for the presence (or lack thereof) of an element in a collection.
+
+* PR bin/44176: Fixed a race condition in atf-run that would crash atf-run
+  when the cleanup of a test case triggered asynchronous modifications to
+  its work directory (e.g. killing a daemon process that cleans up a pid
+  file in the work directory).
+
+* PR bin/44301: Fixed the sample XSLT file to report bogus test programs
+  instead of just listing them as having 0 test cases.
+
+
+Changes in version 0.12
+***********************
+
+Experimental version released on November 7th, 2010.
+
+* Added the ATF_REQUIRE_THROW_RE to atf-c++, which is the same as
+  ATF_REQUIRE_THROW but allows checking for the validity of the exception's
+  error message by means of a regular expression.
+
+* Added the ATF_REQUIRE_MATCH to atf-c++, which allows checking for a
+  regular expression match in a string.
+
+* Changed the default timeout for test cases from 5 minutes to 30 seconds.
+  30 seconds is long enough for virtually all tests to complete, and 5
+  minutes is a way too long pause in a test suite where a single test case
+  stalls.
+
+* Deprecated the use.fs property.  While this seemed like a good idea in
+  the first place to impose more control on what test cases can do, it
+  turns out to be bad.  First, use.fs=false prevents bogus test cases
+  from dumping core so after-the-fact debugging is harder.  Second,
+  supporting use.fs adds a lot of unnecessary complexity.  atf-run will
+  now ignore any value provided to use.fs and will allow test cases to
+  freely access the file system if they wish to.
+
+* Added the atf_tc_get_config_var_as_{bool,long}{,_wd} functions to the atf-c
+  library.  The 'text' module became private in 0.11 but was being used
+  externally to simplify the parsing of configuration variables.
+
+* Made atf-run recognize the 'unprivileged-user' configuration variable
+  and automatically drop root privileges when a test case sets
+  require.user=unprivileged.  Note that this is, by no means, done for
+  security purposes; this is just for user convenience; tests should, in
+  general, not be blindly run as root in the first place.
+
+
+Changes in version 0.11
+***********************
+
+Experimental version released on October 20th, 2010.
+
+* The ATF_CHECK* macros in atf-c++ were renamed to ATF_REQUIRE* to match
+  their counterparts in atf-c.
+
+* Clearly separated the modules in atf-c that are supposed to be public
+  from those that are implementation details.  The header files for the
+  internal modules are not installed any more.
+
+* Made the atf-check tool private.  It is only required by atf-sh and being
+  public has the danger of causing confusion.  Also, making it private
+  simplifies the public API of atf.
+
+* Changed atf-sh to enable per-command error checking (set -e) by default.
+  This catches many cases in which a test case is broken but it is not
+  reported as such because execution continues.
+
+* Fixed the XSTL and CSS stylesheets to support expected failures.
+
+
+Changes in version 0.10
+***********************
+
+Experimental version released on July 2nd, 2010.
+
+Miscellaneous features
+
+* Added expected failures support to test cases and atf-run.  These
+  include, for example, expected clean exits, expected reception of fatal
+  signals, expected timeouts and expected errors in condition checks.
+  These statuses can be used to denote test cases that are known to fail
+  due to a bug in the code they are testing.  atf-report reports these
+  tests separately but they do not count towards the failed test cases
+  amount.
+
+* Added the ATF_CHECK_ERRNO and ATF_REQUIRE_ERRNO to the C library to
+  allow easy checking of call failures that update errno.
+
+* Added the has.cleanup meta-data property to test caes that specifies
+  whether the test case has a cleanup routine or not; its value is
+  automatically set.  This property is read by atf-run to know if it has to
+  run the cleanup routine; skipping this run for every test case
+  significantly speeds up the run time of test suites.
+
+* Reversed the order of the ATF_CHECK_THROW macro in the C++ binding to
+  take the expected exception as the first argument and the statement to
+  execute as the second argument.
+
+Changes in atf-check
+
+* Changed atf-check to support negating the status and output checks by
+  prefixing them with not- and added support to specify multiple checkers
+  for stdout and stderr, not only one.
+
+* Added the match output checker to atf-check to look for regular
+  expressions in the stdout and stderr of commands.
+
+* Modified the exit checks in atf-check to support checking for the
+  reception of signals.
+
+Code simplifications and cleanups
+
+* Removed usage messages from test programs to simplify the
+  implementation of every binding by a significant amount.  They just now
+  refer the user to the appropriate manual page and do not attempt to wrap
+  lines on terminal boundaries.  Test programs are not supposed to be run
+  by users directly so this minor interface regression is not important.
+
+* Removed the atf-format internal utility, which is unused after the
+  change documented above.
+
+* Removed the atf-cleanup internal utility.  It has been unused since the
+  test case isolation was moved to atf-run in 0.8
+
+* Splitted the Makefile.am into smaller files for easier maintenance and
+  dropped the use of M4.  Only affects users building from the repository
+  sources.
+
+* Intermixed tests with the source files in the source tree to provide
+  them more visibility and easier access.  The tests directory is gone from
+  the source tree and tests are now suffixed by _test, not prefixed by t_.
+
+* Simplifications to the atf-c library: removed the io, tcr and ui
+  modules as they had become unnecessary after all simplifications
+  introduced since the 0.8 release.
+
+* Removed the application/X-atf-tcr format introduced in 0.8 release.
+  Tests now print a much simplified format that is easy to parse and nicer
+  to read by end users.  As a side effect, the default for test cases is
+  now to print their results to stdout unless otherwise stated by providing
+  the -r flag.
+
+* Removed XML distribution documents and replaced them with plain-text
+  documents.  They provided little value and introduced a lot of complexity
+  to the build system.
+
+* Simplified the output of atf-version by not attempting to print a
+  revision number when building form a distfile.  Makes the build system
+  easier to maintain.
+
+
+Changes in version 0.9
+**********************
+
+Experimental version released on June 3rd, 2010.
+
+* Added atf-sh, an interpreter to process test programs written using
+  the shell API.  This is not really a shell interpreter by itself though:
+  it is just a wrapper around the system shell that eases the loading of
+  the necessary ATF libraries.
+
+* Removed atf-compile in favour of atf-sh.
+
+* Added the use.fs metadata property to test case, which is used to
+  specify which test cases require file system access.  This is to
+  highlight dependencies on external resources more clearly and to speed up
+  the execution of test suites by skipping the creation of many unnecessary
+  work directories.
+
+* Fixed test programs to get a sane default value for their source
+  directory.  This means that it should not be necessary any more to pass
+  -s when running test programs that do not live in the current directory.
+
+* Defining test case headers became optional.  This is trivial to achieve
+  in shell-based tests but a bit ugly in C and C++.  In C, use the new
+  ATF_TC_WITHOUT_HEAD macro to define the test case, and in C++ use
+  ATF_TEST_CASE_WITHOUT_HEAD.
+
+
+Changes in version 0.8
+**********************
+
+Experimental version released on May 7th, 2010.
+
+* Test programs no longer run several test cases in a row.  The execution
+  of a test program now requires a test case name, and that single test
+  case is executed.  To execute several test cases, use the atf-run utility
+  as usual.
+
+* Test programs no longer fork a subprocess to isolate the execution of
+  test cases.  They run the test case code in-process, and a crash of the
+  test case will result in a crash of the test program.  This is to ease
+  debugging of faulty test cases.
+
+* Test programs no longer isolate their test cases.  This means that they
+  will not create temporary directories nor sanitize the environment any
+  more.  Yes: running a test case that depends on system state by hand will
+  most likely yield different results depending on where (machine,
+  directory, user environment, etc.) it is run.  Isolation has been moved
+  to atf-run.
+
+* Test programs no longer print a cryptic format (application/X-atf-tcs)
+  on a special file channel.  They can now print whatever they want on the
+  screen.  Because test programs can now only run one test case every time,
+  providing controlled output is not necessary any more.
+
+* Test programs no longer write their status into a special file
+  descriptor.  Instead, they create a file with the results, which is later
+  parsed by atf-run.  This changes the semantics of the -r flag.
+
+* atf-run has been adjusted to perform the test case isolation.  As a
+  result, there is now a single canonical place that implements the
+  isolation of test caes.  In previous releases, the three language
+  bindings (C, C++ and shell) had to be kept in sync with each other (read:
+  not a nice thing to do at all).  As a side effect of this change, writing
+  bindings for other languages will be much, much easier from now on.
+
+* atf-run forks test programs on a test case basis, instead of on a test
+  program basis as it did before.  This is to provide the test case
+  isolation that was before implemented by the test programs themselves.
+
+* Removed the atf-exec tool.  This was used to implement test case
+  isolation in atf-sh, but it is now unnecessary.
+
+* It is now optional to define the descr meta-data property.  It has been
+  proven to be mostly useless, because test cases often carry a descriptive
+  name of their own.
+
+
+Changes in version 0.7
+**********************
+
+Experimental version released on December 22nd, 2009.
+
+* Added build-time checks to atf-c and atf-c++.  A binding for atf-sh
+  will come later.
+
+* Migrated all build-time checks for header files to proper ATF tests.
+  This demonstrates the use of the new feature described above.
+
+* Added an internal API for child process management.
+
+* Converted all plain-text distribution documents to a Docbook canonical
+  version, and include pre-generated plain text and HTML copies in the
+  distribution file.
+
+* Simplified the contents of the Makefile.am by regenerating it from a
+  canonical Makefile.am.m4 source.  As a side-effect, some dependency
+  specifications were fixed.
+
+* Migrated all checks from the check target to installcheck, as these
+  require ATF to be installed.
+
+* Fixed sign comparison mismatches triggered by the now-enabled
+  -Wsign-compare.
+
+* Fixed many memory and object leaks.
+
+
+Changes in version 0.6
+**********************
+
+Experimental version released on January 18th, 2009.
+
+* Make atf-exec be able to kill its child process after a certain period
+  of time; this is controlled through the new -t option.
+
+* Change atf-sh to use atf-exec's -t option to control the test case's
+  timeouts, instead of doing it internally.  Same behavior as before, but
+  noticeably faster.
+
+* atf-exec's -g option and atf-killpg are gone due to the previous
+  change.
+
+* Added the atf-check(1) tool, a program that executes a given command
+  and checks its exit code against a known value and allows the management
+  of stdout and stderr in multiple ways.  This replaces the previous
+  atf_check function in the atf-sh library and exposes this functionality
+  to both atf-c and atf-c++.
+
+* Added the ATF_REQUIRE family of macros to the C interface.  These help
+  in checking for fatal test conditions.  The old ATF_CHECK macros now
+  perform non-fatal checks only.  I.e. by using ATF_CHECK, the test case
+  can now continue its execution and the failures will not be reported
+  until the end of the whole run.
+
+* Extended the amount of ATF_CHECK_* C macros with new ones to provide
+  more features to the developer.  These also have their corresponding
+  counterparts in the ATF_REQUIRE_* family.  The new macros (listing the
+  suffixes only) are: _EQ (replaces _EQUAL), _EQ_MSG, _STREQ and
+  _STREQ_MSG.
+
+
+Changes in version 0.5
+**********************
+
+Experimental version released on May 1st, 2008.
+
+* Clauses 3 and 4 of the BSD license used by the project were dropped.
+  All the code is now under a 2-clause BSD license compatible with the GNU
+  General Public License (GPL).
+
+* Added a C-only binding so that binary test programs do not need to be
+  tied to C++ at all.  This binding is now known as the atf-c library.
+
+* Renamed the C++ binding to atf-c++ for consistency with the new atf-c.
+
+* Renamed the POSIX shell binding to atf-sh for consistency with the new
+  atf-c and atf-c++.
+
+* Added a -w flag to test programs through which it is possible to
+  specify the work directory to be used.  This was possible in prior
+  releases by defining the workdir configuration variable (-v workdir=...),
+  but was a conceptually incorrect mechanism.
+
+* Test programs now preserve the execution order of test cases when they
+  are given in the command line.  Even those mentioned more than once are
+  executed multiple times to comply with the user's requests.
+
+
+Changes in version 0.4
+**********************
+
+Experimental version released on February 4th, 2008.
+
+* Added two new manual pages, atf-c++-api and atf-sh-api, describing the
+  C++ and POSIX shell interfaces used to write test programs.
+
+* Added a pkg-config file, useful to get the flags to build against the
+  C++ library or to easily detect the presence of ATF.
+
+* Added a way for test cases to require a specific architecture and/or
+  machine type through the new 'require.arch' and 'require.machine'
+  meta-data properties, respectively.
+
+* Added the 'timeout' property to test cases, useful to set an
+  upper-bound limit for the test's run time and thus prevent global test
+  program stalls due to the test case's misbehavior.
+
+* Added the atf-exec(1) internal utility, used to execute a command
+  after changing the process group it belongs to.
+
+* Added the atf-killpg(1) internal utility, used to kill process groups.
+
+* Multiple portability fixes.  Of special interest, full support for
+  SunOS (Solaris Express Developer Edition 2007/09) using the Sun Studio 12
+  C++ compiler.
+
+* Fixed a serious bug that prevented atf-run(1) from working at all
+  under Fedora 8 x86_64.  Due to the nature of the bug, other platforms
+  were likely affected too.
+
+
+Changes in version 0.3
+**********************
+
+Experimental version released on November 11th, 2007.
+
+* Added XML output support to atf-report.  This is accompanied by a DTD
+  for the format's structure and sample XSLT/CSS files to post-process this
+  output and convert it to a plain HTML report.
+
+* Changed atf-run to add system information to the report it generates.
+  This is currently used by atf-report's XML output only, and is later
+  printed in the HTML reports in a nice and useful summary table.  The user
+  and system administrator are allowed to tune this feature by means of
+  hooks.
+
+* Removed the test cases' 'isolated' property.  This was intended to
+  avoid touching the file system at all when running the related test case,
+  but this has not been true for a long while: some control files are
+  unconditionally required for several purposes, and we cannot easily get
+  rid of them.  This way we remove several critical and delicate pieces of
+  code.
+
+* Improved atf-report's CSV output format to include information about
+  test programs too.
+
+* Fixed the tests that used atf-compile to not require this tool as a
+  helper.  Avoids systems without build-time utilities to skip many tests
+  that could otherwise be run.  (E.g. NetBSD without the comp.tgz set
+  installed.)
+
+* Many general cleanups: Fixed many pieces of code marked as ugly and/or
+  incomplete.
+
+
+Changes in version 0.2
+**********************
+
+Experimental version released on September 20th, 2007.
+
+* Test cases now get a known umask on entry.
+
+* atf-run now detects many unexpected failures caused by test programs and
+  reports them as bogus tests.  atf-report is able to handle these new
+  errors and nicely reports them to the user.
+
+* All the data formats read and written by the tools have been
+  documented and cleaned up.  These include those grammars that define how
+  the different components communicate with each other as well as the
+  format of files written by the developers and users: the Atffiles and the
+  configuration files.
+
+* Added the atf-version tool, a utility that displays information about
+  the currently installed version of ATF.
+
+* Test cases can now define an optional cleanup routine to undo their
+  actions regardless of their exit status.
+
+* atf-report now summarizes the list of failed (bogus) test programs
+  when using the ticker output format.
+
+* Test programs now capture some termination signals and clean up any
+  temporary files before exiting the program.
+
+* Multiple bug fixes and improvements all around.
+
+
+Changes in version 0.1
+**********************
+
+Experimental version released on August 20th, 2007.
+
+* First public version.  This was released coinciding with the end of the
+  Google Summer of Code 2007 program.

+
+
+Introduction
+************
+
+The Automated Testing Framework (ATF) is a collection of libraries and
+utilities designed to ease unattended application testing in the hands of
+developers and end users of a specific piece of software.
+
+As regards developers, ATF provides the necessary means to easily create
+test suites composed of multiple test programs, which in turn are a
+collection of test cases.  It also attempts to simplify the debugging of
+problems when these test cases detect an error by providing as much
+information as possible about the failure.
+
+As regards users, it simplifies the process of running the test suites and,
+in special, encourages end users to run them often: they do not need to
+have source trees around nor any other development tools installed to be
+able to certify that a given piece of software works on their machine as
+advertised.

+Things to do                                    Automated Testing Framework
+===========================================================================
+
+
+Last revised: November 30th, 2010
+
+
+This document includes the list of things that need to be done in ATF that
+are most requested by the users. This information used to be available in
+an ad-hoc bug tracker but that proved to be a bad idea. I have collected
+all worthy comments in here.
+
+Please note that most work these days is going into Kyua (see
+http://code.google.com/p/kyua/). The ideas listed here apply to the
+components of ATF that have *not* been migrated to the new codebase yet.
+For bug reports or ideas that apply to the components that already have
+been migrated, please use the bug tracker in the URL above. Similarly,
+whenever a component is migrated, the ideas in this file should be revised
+and migrated to the new bug tracker where appropriate.
+
+
+---------------------------------------------------------------------------
+Add build-time checks to atf-sh
+
+The 0.7 release introduced build-time tests to atf-c and atf-c++, but not
+to atf-sh. Expose the functionality to the shell interface.
+
+This will probably require writing an atf-build utility that exposes the C
+code and can be called from the shell.
+
+---------------------------------------------------------------------------
+Revisit what to do when an Atffile lists a non-existent file
+
+---------------------------------------------------------------------------
+Add ATF_CHECK* versions to atf-c++ to support non-fatal tests
+
+---------------------------------------------------------------------------
+Implement race-condition tests
+
+gcooper:
+
+I would think that stress/negative tests would be of more value than race
+condition tests (they're similar, but not exactly the same in my mind).
+
+In particular,
+
+1. Feed through as much data as possible to determine where reporting
+   breaks down.
+2. Feed through data quickly and terminate ASAP. The data should be
+   captured. Terminate child applications with unexpected exit codes and
+   signals (in particular, SIGCHLD, SIGPIPE, exit codes that terminate,
+   etc).
+3. Open up a file descriptor in the test application, don't close the file
+   descriptor.
+4. fork(2) a process; don't wait(2) for the application to complete.
+
+There are other scenarios that could be exercised, but these are the ones
+I could think of off the topic of my head.
+
+--
+
+jmmv:
+
+1. The thing is: how do you express any of this in a portable/abstract
+   interface? How do you express that a test case "receives data"? What
+   does that exactly mean? I don't think the framework should care about
+   this: each test should be free to decide where its data is and how to
+   deal with it.
+
+2. Ditto.
+
+3. Not sure I understand your request, but testing for "unexpected exit
+   codes" is already supported. See wiki:DesignXFail for the feature
+   design details.
+
+4. What's the problem with this case? The test case exits right away after
+   terminating the execution of its body; any open file descriptors,
+   leaked memory, etc. die with it.
+
+5. forking and not waiting for a subprocess was a problem already
+   addressed.
+
+I kinda have an idea of what Antti means with "race condition tests", but
+every time I have tried to describe my understanding of matters I seem to
+be wrong. Would be nice to have a clear description of what this involves;
+in particular, what are the expectations from the framework and how should
+the feature be exposed.
+
+As of now, what I understand by "race condition test" is: a test case that
+exercises a race condition. The test case may finish without triggering
+the race, in which case it just exists with a successful status.
+Otherwise, if the race triggers, the test case gets stuck and times out.
+The result should be reported as an "expected failure" different from
+timeout.
+
+--
+
+pooka:
+
+Yup. Plus some atf-wide mechanism for the operator to supply some kind of
+guideline if the test should try to trigger the race for a second or for
+an hour.
+
+--
+
+jmmv:
+
+Alright. While mocking up some code for this, I think that your two
+requests are complementary.
+
+On the one hand, when you are talking about a "race condition" test you
+really mean an "expected race condition" test. Correct? If so, we need to
+extend the xfail mechanism to add one more case, which is to report any
+failures as a race condition error and, if there is no failure, report the
+test as successful.
+
+On the other hand, the atf-wide mechanism to support how long the test
+should run for can be thought as a "stress test" mechanism. I.e. run this
+test for X time / iterations and report its results regularly without
+involving xfail at all.
+
+So, with this in mind:
+
+* For a test that triggers an unfixed race condition, you set xfail to
+  race mode and define the test as a stress test. Any failures are
+  reported as expected failures.
+
+* For a test that verifies a supposedly-fixed race condition, you do *not*
+  set xfail to race mode, and only set the test to stress test. Any
+  failures are reported as real failures.
+
+These stress test cases implement a single iteration of the test and
+atf-run is in charge of running the test several times, stopping on the
+first failure.
+
+Does that make sense?
+
+---------------------------------------------------------------------------
+Implement ATF_REQUIRE_ERRNO
+
+pooka:
+
+Most of the lines in tests against system functionality are:
+
+if (syscall(args) == -1)
+    atf_tc_fail_errno("flop")
+
+Some shorthand would be helpful, like ATF_REQUIRE_ERRNO(syscall(args))
+Also, a variant which allows arbitrary return value checks (e.g. "!= 0" or
+"< 124" or "!= size") would be nice.
+
+--
+
+gcooper:
+
+There's a problem with this request; not all functions fail in the same
+way ... in particular compare the pthread family of functions (which
+return errno) vs many native syscalls. Furthermore, compare some
+fcntl-like syscalls vs other syscalls. One size fits all solutions may not
+be a wise idea in this case, so I think that the problem statement needs
+to be better defined, because the above request is too loose.
+
+FWIW, there's also a TEST macro in LTP, which tests for non-zero status,
+and sets an appropriate set of global variables for errnos and return
+codes, respectively. It was a good idea, but has been mostly abandoned
+because it's too difficult to define a success and failure in a universal
+manner, so I think that we need to be careful with what's implemented in
+ATF to not repeat the mistakes that others have made.
+
+--
+
+jmmv:
+
+I think you've got a good point.
+
+This was mostly intended to simplify the handling of the stupid errno
+global variable. I think this is valuable to have, but maybe the
+macro/function name should be different because _ERRNO can be confusing.
+Probably something like an ATF_CHECK_LIBC / ATF_CHECK_PTHREAD approach
+would be more flexible and simple.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.

+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases

+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.

+.Sh DESCRIPTION
+ATF provides a mostly-macro-based programming interface to implement test
+programs in C or C++.
+This interface is backed by a C++ implementation, but this fact is
+hidden from the developer as much as possible through the use of
+macros to simplify programming.
+However, the use of C++ is not hidden everywhere and while you can
+implement test cases without knowing anything at all about the object model
+underneath the provided calls, you might need some minimum notions of the
+language in very specific circumstances.
+.Pp
+C++-based test programs always follow this template:
+.Bd -literal -offset indent
+extern "C" {
+.Ns ... C-specific includes go here ...
+}
+
+.Ns ... C++-specific includes go here ...

+    ATF_ADD_TEST_CASE(tcs, tc3);
+    ... add additional test cases ...
+}
+.Ed
+.Ss Definition of test cases
+Test cases have an identifier and are composed of three different parts:
+the header, the body and an optional cleanup routine, all of which are
+described in
+.Xr atf-test-case 4 .
+To define test cases, one can use the
+.Fn ATF_TEST_CASE ,
+.Fn ATF_TEST_CASE_WITH_CLEANUP
+or the
+.Fn ATF_TEST_CASE_WITHOUT_HEAD
+macros, which take a single parameter specifiying the test case's
+name.
+.Fn ATF_TEST_CASE ,
+requires to define a head and a body for the test case,
+.Fn ATF_TEST_CASE_WITH_CLEANUP
+requires to define a head, a body and a cleanup for the test case and
+.Fn ATF_TEST_CASE_WITHOUT_HEAD
+requires only a body for the test case.
+It is important to note that these
+.Em do not
+set the test case up for execution when the program is run.
+In order to do so, a later registration is needed through the
+.Fn ATF_ADD_TEST_CASE
+macro detailed in
+.Sx Program initialization .
+.Pp
+Later on, one must define the three parts of the body by means of three
+functions.
+Their headers are given by the
+.Fn ATF_TEST_CASE_HEAD ,
+.Fn ATF_TEST_CASE_BODY
+and
+.Fn ATF_TEST_CASE_CLEANUP
+macros, all of which take the test case's name.
+Following each of these, a block of code is expected, surrounded by the
+opening and closing brackets.
+.Pp
+Additionally, the
+.Fn ATF_TEST_CASE_NAME
+macro can be used to obtain the name of the class corresponding to a
+particular test case, as the name is internally manged by the library to
+prevent clashes with other user identifiers.
+Similarly, the
+.Fn ATF_TEST_CASE_USE
+macro can be executed on a particular test case to mark it as "used" and
+thus prevent compiler warnings regarding unused symbols.
+Note that
+.Em you should never have to use these macros during regular operation.
+.Ss Program initialization
+The library provides a way to easily define the test program's
+.Fn main
+function.
+You should never define one on your own, but rely on the
+library to do it for you.
+This is done by using the
+.Fn ATF_INIT_TEST_CASES
+macro, which is passed the name of the list that will hold the test cases.
+This name can be whatever you want as long as it is a valid variable value.
+.Pp
+After the macro, you are supposed to provide the body of a function, which
+should only use the
+.Fn ATF_ADD_TEST_CASE
+macro to register the test cases the test program will execute.
+The first parameter of this macro matches the name you provided in the
+former call.
+.Ss Header definitions
+The test case's header can define the meta-data by using the
+.Fn set
+method, which takes two parameters: the first one specifies the
+meta-data variable to be set and the second one specifies its value.
+Both of them are strings.
+.Ss Configuration variables
+The test case has read-only access to the current configuration variables
+by means of the
+.Ft bool
+.Fn has_config_var
+and the
+.Ft std::string
+.Fn get_config_var
+methods, which can be called in any of the three parts of a test case.
+.Ss Access to the source directory
+It is possible to get the path to the test case's source directory from any
+of its three components by querying the
+.Sq srcdir
+configuration variable.
+.Ss Requiring programs
+Aside from the
+.Va require.progs
+meta-data variable available in the header only, one can also check for
+additional programs in the test case's body by using the
+.Fn require_prog
+function, which takes the base name or full path of a single binary.
+Relative paths are forbidden.
+If it is not found, the test case will be automatically skipped.
+.Ss Test case finalization
+The test case finalizes either when the body reaches its end, at which
+point the test is assumed to have
+.Em passed ,
+or at any explicit call to
+.Fn ATF_PASS ,
+.Fn ATF_FAIL
+or
+.Fn ATF_SKIP .
+These three macros terminate the execution of the test case immediately.
+The cleanup routine will be processed afterwards in a completely automated
+way, regardless of the test case's termination reason.
+.Pp
+.Fn ATF_PASS
+does not take any parameters.
+.Fn ATF_FAIL
+and
+.Fn ATF_SKIP
+take a single string that describes why the test case failed or
+was skipped, respectively.
+It is very important to provide a clear error message in both cases so that
+the user can quickly know why the test did not pass.
+.Ss Expectations
+Everything explained in the previous section changes when the test case
+expectations are redefined by the programmer.
+.Pp
+Each test case has an internal state called
+.Sq expect
+that describes what the test case expectations are at any point in time.
+The value of this property can change during execution by any of:
+.Bl -tag -width indent
+.It Fn expect_death "reason"
+Expects the test case to exit prematurely regardless of the nature of the
+exit.
+.It Fn expect_exit "exitcode" "reason"
+Expects the test case to exit cleanly.
+If
+.Va exitcode
+is not
+.Sq -1 ,
+.Xr atf-run 1
+will validate that the exit code of the test case matches the one provided
+in this call.
+Otherwise, the exact value will be ignored.
+.It Fn expect_fail "reason"
+Any failure (be it fatal or non-fatal) raised in this mode is recorded.
+However, such failures do not report the test case as failed; instead, the
+test case finalizes cleanly and is reported as
+.Sq expected failure ;
+this report includes the provided
+.Fa reason
+as part of it.
+If no error is raised while running in this mode, then the test case is
+reported as
+.Sq failed .
+.Pp
+This mode is useful to reproduce actual known bugs in tests.
+Whenever the developer fixes the bug later on, the test case will start
+reporting a failure, signaling the developer that the test case must be
+adjusted to the new conditions.
+In this situation, it is useful, for example, to set
+.Fa reason
+as the bug number for tracking purposes.
+.It Fn expect_pass
+This is the normal mode of execution.
+In this mode, any failure is reported as such to the user and the test case
+is marked as
+.Sq failed .
+.It Fn expect_race "reason"
+Any failure or timeout during the execution of the test case will be
+considered as if a race condition has been triggered and reported as such.
+If no problems arise, the test will continue execution as usual.
+.It Fn expect_signal "signo" "reason"
+Expects the test case to terminate due to the reception of a signal.
+If
+.Va signo
+is not
+.Sq -1 ,
+.Xr atf-run 1
+will validate that the signal that terminated the test case matches the one
+provided in this call.
+Otherwise, the exact value will be ignored.
+.It Fn expect_timeout "reason"
+Expects the test case to execute for longer than its timeout.
+.El
+.Ss Helper macros for common checks
+The library provides several macros that are very handy in multiple
+situations.
+These basically check some condition after executing a given statement or
+processing a given expression and, if the condition is not met, they
+automatically call
+.Fn ATF_FAIL
+with an appropriate error message.
+.Pp
+.Fn ATF_REQUIRE
+takes an expression and raises a failure if it evaluates to false.

+.Fn ATF_REQUIRE_EQ
+takes two expressions and raises a failure if the two do not evaluate to
+the same exact value.
+.Pp
+.Fn ATF_REQUIRE_IN
+takes an element and a collection and validates that the element is present in
+the collection.
+.Pp
+.Fn ATF_REQUIRE_MATCH
+takes a regular expression and a string and raises a failure if the regular
+expression does not match the string.
+.Pp
+.Fn ATF_REQUIRE_NOT_IN
+takes an element and a collection and validates that the element is not present
+in the collection.
+.Pp
+.Fn ATF_REQUIRE_THROW
+takes the name of an exception and a statement and raises a failure if
+the statement does not throw the specified exception.
+.Fn ATF_REQUIRE_THROW_EQ
+takes the name of an exception, a regular expresion and a statement and raises a
+failure if the statement does not throw the specified exception and if the
+message of the exception does not match the regular expression.
+.Pp
+.Fn ATF_CHECK_ERRNO
+and
+.Fn ATF_REQUIRE_ERRNO
+take, first, the error code that the check is expecting to find in the

+.Ed
+.Ss Definition of test cases
+Test cases have an identifier and are composed of three different parts:
+the header, the body and an optional cleanup routine, all of which are
+described in
+.Xr atf-test-case 4 .
+To define test cases, one can use the
+.Fn ATF_TC ,
+.Fn ATF_TC_WITH_CLEANUP
+or the
+.Fn ATF_TC_WITHOUT_HEAD
+macros, which take a single parameter specifiying the test case's name.
+.Fn ATF_TC ,
+requires to define a head and a body for the test case,
+.Fn ATF_TC_WITH_CLEANUP
+requires to define a head, a body and a cleanup for the test case and
+.Fn ATF_TC_WITHOUT_HEAD
+requires only a body for the test case.
+It is important to note that these
+.Em do not
+set the test case up for execution when the program is run.
+In order to do so, a later registration is needed with the
+.Fn ATF_TP_ADD_TC
+macro detailed in
+.Sx Program initialization .
+.Pp
+Later on, one must define the three parts of the body by means of three
+functions.
+Their headers are given by the
+.Fn ATF_TC_HEAD ,
+.Fn ATF_TC_BODY
+and
+.Fn ATF_TC_CLEANUP
+macros, all of which take the test case name provided to the
+.Fn ATF_TC
+.Fn ATF_TC_WITH_CLEANUP ,
+or
+.Fn ATF_TC_WITHOUT_HEAD
+macros and the name of the variable that will hold a pointer to the
+test case data.
+Following each of these, a block of code is expected, surrounded by the
+opening and closing brackets.
+.Ss Program initialization
+The library provides a way to easily define the test program's
+.Fn main
+function.
+You should never define one on your own, but rely on the
+library to do it for you.
+This is done by using the
+.Fn ATF_TP_ADD_TCS
+macro, which is passed the name of the object that will hold the test
+cases; i.e. the test program instance.
+This name can be whatever you want as long as it is a valid variable
+identifier.
+.Pp
+After the macro, you are supposed to provide the body of a function, which
+should only use the
+.Fn ATF_TP_ADD_TC
+macro to register the test cases the test program will execute and return
+a success error code.
+The first parameter of this macro matches the name you provided in the
+former call.
+The success status can be returned using the
+.Fn atf_no_error
+function.
+.Ss Header definitions
+The test case's header can define the meta-data by using the
+.Fn atf_tc_set_md_var
+method, which takes three parameters: the first one points to the test
+case data, the second one specifies the meta-data variable to be set
+and the third one specifies its value.
+Both of them are strings.
+.Ss Configuration variables
+The test case has read-only access to the current configuration variables
+by means of the
+.Ft bool
+.Fn atf_tc_has_config_var ,
+.Ft const char *
+.Fn atf_tc_get_config_var ,
+.Ft const char *
+.Fn atf_tc_get_config_var_wd ,
+.Ft bool
+.Fn atf_tc_get_config_var_as_bool ,
+.Ft bool
+.Fn atf_tc_get_config_var_as_bool_wd ,
+.Ft long
+.Fn atf_tc_get_config_var_as_long ,
+and the
+.Ft long
+.Fn atf_tc_get_config_var_as_long_wd
+functions, which can be called in any of the three parts of a test case.
+.Pp
+The
+.Sq _wd
+variants take a default value for the variable which is returned if the
+variable is not defined.
+The other functions without the
+.Sq _wd
+suffix
+.Em require
+the variable to be defined.
+.Ss Access to the source directory
+It is possible to get the path to the test case's source directory from any
+of its three components by querying the
+.Sq srcdir
+configuration variable.
+.Ss Requiring programs
+Aside from the
+.Va require.progs
+meta-data variable available in the header only, one can also check for
+additional programs in the test case's body by using the
+.Fn atf_tc_require_prog
+function, which takes the base name or full path of a single binary.
+Relative paths are forbidden.
+If it is not found, the test case will be automatically skipped.
+.Ss Test case finalization
+The test case finalizes either when the body reaches its end, at which
+point the test is assumed to have
+.Em passed ,
+unless any non-fatal errors were raised using
+.Fn atf_tc_fail_nonfatal ,
+or at any explicit call to
+.Fn atf_tc_pass ,
+.Fn atf_tc_fail
+or
+.Fn atf_tc_skip .
+These three functions terminate the execution of the test case immediately.
+The cleanup routine will be processed afterwards in a completely automated
+way, regardless of the test case's termination reason.
+.Pp
+.Fn atf_tc_pass
+does not take any parameters.
+.Fn atf_tc_fail ,
+.Fn atf_tc_fail_nonfatal
+and
+.Fn atf_tc_skip
+take a format string and a variable list of parameters, which describe, in
+a user-friendly manner, why the test case failed or was skipped,
+respectively.
+It is very important to provide a clear error message in both cases so that
+the user can quickly know why the test did not pass.
+.Ss Expectations
+Everything explained in the previous section changes when the test case
+expectations are redefined by the programmer.
+.Pp
+Each test case has an internal state called
+.Sq expect
+that describes what the test case expectations are at any point in time.
+The value of this property can change during execution by any of:
+.Bl -tag -width indent
+.It Fn atf_tc_expect_death "reason" "..."
+Expects the test case to exit prematurely regardless of the nature of the
+exit.
+.It Fn atf_tc_expect_exit "exitcode" "reason" "..."
+Expects the test case to exit cleanly.
+If
+.Va exitcode
+is not
+.Sq -1 ,
+.Xr atf-run 1
+will validate that the exit code of the test case matches the one provided
+in this call.
+Otherwise, the exact value will be ignored.
+.It Fn atf_tc_expect_fail "reason" "..."
+Any failure (be it fatal or non-fatal) raised in this mode is recorded.
+However, such failures do not report the test case as failed; instead, the
+test case finalizes cleanly and is reported as
+.Sq expected failure ;
+this report includes the provided
+.Fa reason
+as part of it.
+If no error is raised while running in this mode, then the test case is
+reported as
+.Sq failed .
+.Pp
+This mode is useful to reproduce actual known bugs in tests.
+Whenever the developer fixes the bug later on, the test case will start
+reporting a failure, signaling the developer that the test case must be
+adjusted to the new conditions.
+In this situation, it is useful, for example, to set
+.Fa reason
+as the bug number for tracking purposes.
+.It Fn atf_tc_expect_pass
+This is the normal mode of execution.
+In this mode, any failure is reported as such to the user and the test case
+is marked as
+.Sq failed .
+.It Fn atf_tc_expect_signal "signo" "reason" "..."
+Expects the test case to terminate due to the reception of a signal.
+If
+.Va signo
+is not
+.Sq -1 ,
+.Xr atf-run 1
+will validate that the signal that terminated the test case matches the one
+provided in this call.
+Otherwise, the exact value will be ignored.
+.It Fn atf_tc_expect_timeout "reason" "..."
+Expects the test case to execute for longer than its timeout.
+.El
+.Ss Helper macros for common checks
+The library provides several macros that are very handy in multiple
+situations.
+These basically check some condition after executing a given statement or
+processing a given expression and, if the condition is not met, they
+report the test case as failed.
+.Pp
+The
+.Sq REQUIRE
+variant of the macros immediately abort the test case as soon as an error
+condition is detected by calling the
+.Fn atf_tc_fail
+function.
+Use this variant whenever it makes now sense to continue the execution of a
+test case when the checked condition is not met.
+The
+.Sq CHECK
+variant, on the other hand, reports a failure as soon as it is encountered
+using the
+.Fn atf_tc_fail_nonfatal
+function, but the execution of the test case continues as if nothing had
+happened.
+Use this variant whenever the checked condition is important as a result of
+the test case, but there are other conditions that can be subsequently
+checked on the same run without aborting.
+.Pp
+Additionally, the
+.Sq MSG
+variants take an extra set of parameters to explicitly specify the failure
+message.
+This failure message is formatted according to the
+.Xr printf 3
+formatters.
+.Pp
+.Fn ATF_CHECK ,
+.Fn ATF_CHECK_MSG ,
+.Fn ATF_REQUIRE
+and
+.Fn ATF_REQUIRE_MSG
+take an expression and fail if the expression evaluates to false.
+.Pp
+.Fn ATF_CHECK_EQ ,
+.Fn ATF_CHECK_EQ_MSG ,
+.Fn ATF_REQUIRE_EQ
+and
+.Fn ATF_REQUIRE_EQ_MSG
+take two expressions and fail if the two evaluated values are not equal.
+.Pp
+.Fn ATF_CHECK_STREQ ,
+.Fn ATF_CHECK_STREQ_MSG ,
+.Fn ATF_REQUIRE_STREQ
+and
+.Fn ATF_REQUIRE_STREQ_MSG
+take two strings and fail if the two are not equal character by character.
+.Pp
+.Fn ATF_CHECK_ERRNO
+and
+.Fn ATF_REQUIRE_ERRNO
+take, first, the error code that the check is expecting to find in the
+.Va errno
+variable and, second, a boolean expression that, if evaluates to true,
+means that a call failed and
+.Va errno
+has to be checked against the first value.

+.Sh NAME
+.Nm atf-config
+.Nd queries static configuration information of ATF
+.Sh SYNOPSIS
+.Nm
+.Op Fl t
+.Op Ar var1 Op Ar .. varN
+.Nm
+.Fl h
+.Sh DESCRIPTION
+.Nm
+is a utility that queries static configuration information of ATF.
+Static configuration refers to all those values for settings that
+were built into the ATF binaries at build time.
+.Pp
+In the first synopsis form,
+.Nm
+will print variable-value pairs for all built-in static variables if
+no variable names are provided as arguments.
+If any is provided, it will only print the variable-value pairs for
+those variables.
+The output of the utility does not use the
+.Sq =
+symbol to separate the variable name from its corresponding value in
+an attempt to avoid sourcing the output in shell scripts or Makefiles.
+If you need to do that, the
+.Fl t
+flag allows you to query the value of individual variables without any
+surrounding text.
+.Pp
+In the second synopsis form,
+.Nm
+will print information about all supported options and their purpose.
+.Pp
+The following options are available:
+.Bl -tag -width flag
+.It Fl h
+Shows a short summary of all available options and their purpose.
+.It Fl t
+Changes the output of the utility to show the variable values, one
+per line, without the variable names.
+.El
+.Ss Static configuration variables
+The following list describes all the variables that are part of ATF's
+static configuration:
+.Bl -tag -width atfXbuildXcppflagsXX
+.It Va atf_arch
+The architecture name detected by ATF.
+This is derived from
+.Va atf_machine
+because it is a subset of it.
+Given that this name might be misdetected, it is provided to the user
+as a configuration variable so that he can fix its value temporarily
+until a real fix is incorporated into mainstream sources.
+.It Va atf_build_cc
+The C compiler used by the ATF checks that provide build-time tests.
+.It Va atf_build_cflags
+The C compiler flags used by the ATF checks that provide build-time tests.
+.It Va atf_build_cpp
+The C/C++ preprocessor used by the ATF checks that provide build-time tests.
+.It Va atf_build_cppflags
+The C/C++ preprocessor flags used by the ATF checks that provide build-time
+tests.
+.It Va atf_build_cxx
+The C++ compiler used by the ATF checks that provide build-time tests.
+.It Va atf_build_cxxflags
+The C++ compiler flags used by the ATF checks that provide build-time tests.
+.It Va atf_confdir
+The path to the directory that contains the system-wide configuration
+files for ATF.
+.It Va atf_includedir
+The path to the directory that contains the ATF header files.
+.It Va atf_libdir
+The path to the directory that contains the ATF libraries.
+.It Va atf_libexecdir
+The path to the directory that contains the auxiliary utilities of ATF,
+used internally by the public tools.
+.It Va atf_machine
+The machine type name detected by ATF.
+This should not be tunable but is provided for symmetry with
+.Va atf_arch .
+.It Va atf_pkgdatadir
+The path to the directory that contains the files that form the ATF's
+shell-scripting library.
+.It Va atf_shell
+The path to the shell interpreter that will be used by ATF.
+.It Va atf_workdir
+The path to the temporary directory that the utilities and the test
+programs will use to store temporary files in.
+.El
+.Sh ENVIRONMENT
+Every variable that is part of the static configuration can be
+overridden at run-time by defining an environment variable.
+This environment variable has the exact same name as the one shown by
+.Nm
+except that the name is all composed of uppercase letters.
+.Pp
+In general, empty values in the environment will be ignored unless
+otherwise noted below.
+.Pp
+The recognized environment variables are:
+.Bl -tag -width ATFXBUILDXCPPFLAGSXX
+.It Ev ATF_ARCH
+Overrides the built-in value of
+.Va atf_arch .
+.It Ev ATF_BUILD_CC
+Overrides the built-in value of
+.Va atf_build_cc .
+.It Ev ATF_BUILD_CFLAGS
+Overrides the built-in value of
+.Va atf_build_cflags .
+Empty values are allowed.
+.It Ev ATF_BUILD_CPP
+Overrides the built-in value of
+.Va atf_build_cpp .
+.It Ev ATF_BUILD_CPPFLAGS
+Overrides the built-in value of
+.Va atf_build_cppflags .
+Empty values are allowed.
+.It Ev ATF_BUILD_CXX
+Overrides the built-in value of
+.Va atf_build_cxx .
+.It Ev ATF_BUILD_CXXFLAGS
+Overrides the built-in value of
+.Va atf_build_cxxflags .
+Empty values are allowed.
+.It Ev ATF_CONFDIR
+Overrides the built-in value of
+.Va atf_confdir .
+.It Ev ATF_INCLUDEDIR
+Overrides the built-in value of
+.Va atf_includedir .
+.It Ev ATF_LIBDIR
+Overrides the built-in value of
+.Va atf_libdir .
+.It Ev ATF_LIBEXECDIR
+Overrides the built-in value of
+.Va atf_libexecdir .
+.It Ev ATF_MACHINE
+Overrides the built-in value of
+.Va atf_machine .
+.It Ev ATF_PKGDATADIR
+Overrides the built-in value of
+.Va atf_pkgdatadir .
+.It Ev ATF_SHELL
+Overrides the built-in value of
+.Va atf_shell .
+.It Ev ATF_WORKDIR
+Overrides the built-in value of
+.Va atf_workdir .

+.Sh NAME
+.Nm atf-report
+.Nd transforms the output of atf-run to different formats
+.Sh SYNOPSIS
+.Nm
+.Op Fl o Ar fmt1:path1 Op .. Fl o Ar fmtN:pathN
+.Nm
+.Fl h
+.Sh DESCRIPTION
+.Nm
+reads the output of
+.Nm atf-run
+and transforms it to different formats.
+Some of these are user-friendly and others are machine-parseable, which
+opens a wide range of possibilities to analyze the results of a test
+suite's execution.
+See
+.Sx Output formats
+below for more details on which these formats are.
+.Pp
+In the first synopsis form,
+.Nm
+reads the output of
+.Nm atf-run
+through its standard input and, if no
+.Fl o
+options are given, prints a user-friendly report on its standard
+output using the
+.Sq ticker
+format.
+If
+.Fl o
+options are provided (more than one are allowed), they specify the complete
+list of reports to generate.
+They are all generated simultaneously, and for obvious reasons, two reports
+cannot be written to the same file.
+Note that the default output is suppressed when
+.Fl o
+is provided.
+.Pp
+In the second synopsis form,
+.Nm
+will print information about all supported options and their purpose.
+.Pp
+The following options are available:
+.Bl -tag -width XoXfmtXpathXX
+.It Fl h
+Shows a short summary of all available options and their purpose.
+.It Fl o Ar fmt:path
+Adds a new output format.
+.Ar fmt
+is one of the formats described later on in
+.Sx Output formats .
+.Ar path
+specifies where the report will be written to.
+Depending on the chosen format, this may refer to a single file or to
+a directory.
+For those formats that write to a single file, specifying a
+.Sq -
+as the path will redirect the report to the standard output.
+.El
+.Ss Output formats
+The following output formats are allowed:
+.Bl -tag -width tickerXX
+.It csv
+A machine-parseable Comma-Separated Values (CSV) file.
+This file contains the results for all test cases and test programs.
+Test cases are logged using the following syntax:
+.Bd -literal -offset indent
+tc, duration, test-program, test-case, result[, reason]
+.Ed
+.Pp
+The
+.Sq result
+field for test cases is always one of
+.Sq passed ,
+.Sq skipped
+or
+.Sq failed .
+The last two are always followed by a reason.
+.Pp
+Test programs are logged with the following syntax:
+.Bd -literal -offset indent
+tp, duration, test-program, result[, reason]
+.Ed
+.Pp
+In this case, the
+.Sq result
+can be one of:
+.Sq passed ,
+which denotes test programs that ran without any failure;
+.Sq failed ,
+which refers to test programs in which one or more test cases failed;
+or
+.Sq bogus ,
+which mentions those test programs that failed to execute by some reason.
+The reason field is only available in the last case.
+.Pp
+The time required to execute each test case and test program is
+also provided.
+You should not rely on the order of the entries in the resulting output.
+.It ticker
+A user-friendly report that shows the progress of the test suite's
+execution as it operates.
+This type of report should always be redirected to a virtual terminal,
+not a file, as it may use control sequences that will make the output
+unreadable in regular files.
+.It xml
+A report contained in a single XML file.
+Ideal for later processing with
+.Xr xsltproc 1
+to generate nice HTML reports.
+.El
+.Sh EXAMPLES
+The most simple way of running a test suite is to pipe the output of
+.Nm atf-run
+through
+.Nm
+without any additional flags.
+This will use the default output format, which is suitable to most users:
+.Bd -literal -offset indent
+atf-run | atf-report
+.Ed
+.Pp
+In some situations, it may be interesting to get a machine-parseable file
+aside from the standard report.
+This can be done as follows:
+.Bd -literal -offset indent
+atf-run | atf-report -o csv:testsuite.csv -o ticker:-
+.Ed
+.Pp
+Or if the standard report is not desired, thus achieving completely silent
+operation:
+atf-run | atf-report -o csv:testsuite.csv
+.Sh SEE ALSO
+.Xr atf-run 1 ,
+.Xr atf 7

+//! This class is not tied to a output stream nor a file because, depending

+//! multiple ones.

+.Sh NAME
+.Nm atf-run
+.Nd executes a collection of test programs
+.Sh SYNOPSIS
+.Nm
+.Op Fl v Ar var1=value1 Op .. Fl v Ar varN=valueN
+.Op Ar test_program1 Op Ar .. test_programN
+.Nm
+.Fl h
+.Sh DESCRIPTION
+.Nm
+executes a collection of test programs or, in other words, a complete
+test suite.
+The results of each test program are collected by the tool, and are then
+multiplexed into a single machine-parseable report; see
+.Xr atf-formats 5
+for more details.
+This report can later be transformed into many different and saner formats
+using the
+.Nm atf-report
+tool.
+.Pp
+The list of test programs to execute is read from an
+.Pa Atffile
+present in the current directory.
+This file describes the test suite stored in the directory it lives in,
+which aside from the list of test programs also includes meta-data and
+configuration variables.
+.Pp
+.Nm
+is also in charge of reading the configuration files that tune the behavior
+of each test program and passing down the necessary variables to them.
+More details on how this is done are given in the
+.Sx Configuration
+section.
+.Pp
+In the first synopsis form,
+.Nm
+parses the
+.Pa Atffile
+in the current directory and runs all the test programs specified in it.
+If any test program names are given as part of the command line, those are
+the ones executed instead of the complete list.
+.Pp
+In the second synopsis form,
+.Nm
+will print information about all supported options and their purpose.
+.Pp
+The following options are available:
+.Bl -tag -width XvXvarXvalueXX
+.It Fl h
+Shows a short summary of all available options and their purpose.
+.It Fl v Ar var=value
+Sets the configuration variable
+.Ar var
+to the given value
+.Ar value .
+.El
+.Ss Configuration
+.Nm
+reads configuration data from multiple places.
+After all of these places have been analyzed, a list of variable-value
+pairs are passed to the test programs to be run.
+.Pp
+The following locations are scanned for configuration data, in order.
+Items down the list override values defined above them:
+.Bl -enum
+.It
+Configuration variables defined in the
+.Pa Atffile .
+.It
+Configuration variables defined in the system-wide configuration file
+shared among all test suites.
+This lives in
+.Pa ${ATF_CONFDIR}/common.conf .
+.It
+Configuration variables defined in the system-wide test-suite-specific
+configuration file.
+This lives in
+.Pa ${ATF_CONFDIR}/<test-suite>.conf .
+.It
+Configuration variables defined in the user-specific configuration file
+shared among all test suites.
+This lives in
+.Pa ${HOME}/.atf/common.conf .
+.It
+Configuration variables defined in the user-specific test-suite-specific
+configuration file.
+This lives in
+.Pa ${HOME}/.atf/<test-suite>.conf .
+.It
+Configuration variables provided as part of the command line through the
+.Fl v
+option.
+.El
+.Pp
+The value of
+.Va ATF_CONFDIR
+in the above list determined as detailed in
+.Xr atf-config 1 .
+.Pp
+The following configuration variables are globally recognized:
+.Bl -tag -width XunprivilegedXuserXX
+.It Va unprivileged-user
+The name of the system user that atf-run will drop root privileges into
+for test cases defining
+.Sq require.user=unprivileged .
+Note that this is
+.Em not provided for security purposes ;
+this feature is only for the convenience of the user.
+.El
+.Ss Hooks
+.Nm Ns 's
+internal behavior can be customized by the system administrator and the
+user by means of hooks.
+These hooks are written in the shell script language for simplicity and
+are stored in the following files, which are read in the order provided
+below:
+.Bl -enum
+.It
+${ATF_CONFDIR}/atf-run.hooks
+.It
+${HOME}/.atf/atf-run.hooks
+.El
+.Pp
+The following hooks are supported:
+.Bl -tag -width infoXstartXhookXX
+.It info_start_hook
+Called before
+.Nm
+executes any test program.
+The purpose of this hook is to write additional
+.Sq info
+stanzas to the top of the output report; these are defined by the
+.Sq application/X-atf-tps format
+described in
+.Xr atf-formats 5 .
+Always use the
+.Sq atf_tps_writer_info
+function to print these.
+.Pp
+This takes no parameters.
+.It info_end_hook
+Similar to
+.Sq info_start_hook
+but executed after all test programs have been run so that additional
+.Sq info
+stanzas can be added to the bottom of the output report.
+.Pp
+This takes no parameters.
+.El
+.Pp
+All hooks are accompanied by a function named
+.Sq default_<hook_name>
+that can be executed by them to invoke the default behavior built into
+.Nm .
+For example, in order to extend the default
+.Sq info_start_hook
+hook, we could write the following function:
+.Bd -literal -offset indent
+info_start_hook()
+{
+    default_info_start_hook "${@}"
+
+    atf_tps_writer_info "uptime" "$(uptime)"
+}

+//! \brief Simple RAII model for system file handles.
+//!
+//! The \a file_handle class is a simple RAII model for native system file
+//! handles.  This class wraps one of such handles grabbing its ownership,
+//! and automaticaly closes it upon destruction.  It is basically used
+//! inside the library to avoid leaking open file handles, shall an
+//! unexpected execution trace occur.
+//!
+//! A \a file_handle object can be copied but doing so invalidates the
+//! source object.  There can only be a single valid \a file_handle object
+//! for a given system file handle.  This is similar to std::auto_ptr\<\>'s
+//! semantics.
+//!
+//! This class also provides some convenience methods to issue special file
+//! operations under their respective platforms.

+//! The pistream class represents an output communication channel with the

+//! stream can block if the associated file handle blocks during the read.
+//! As this class is used to communicate with child processes through
+//! anonymous pipes, the most typical blocking condition happens when the
+//! child has no more data to send to the pipe's system buffer.  When
+//! this happens, the buffer eventually empties and the system blocks
+//! until the writer generates some data.

+.Os
+.Sh NAME
+.Nm atf-check
+.Nd executes a command and analyzes its results
+.Sh SYNOPSIS
+.Nm
+.Op Fl s Ar qual:value
+.Op Fl o Ar action:arg ...
+.Op Fl e Ar action:arg ...
+.Op Fl x
+.Ar command
+.Nm
+.Fl h
+.Sh DESCRIPTION
+.Nm
+executes a given command and analyzes its results, including
+exit code, stdout and stderr.
+.Pp
+In the first synopsis form,
+.Nm
+will execute the provided command and apply checks specified
+by arguments.
+By default it will act as if it was run with
+.Fl s
+.Ar exit:0
+.Fl o
+.Ar empty
+.Fl e
+.Ar empty .
+Multiple checks for the same output channel are allowed and, if specified,
+their results will be combined as a logical and (meaning that the output must
+match all the provided checks).
+.Pp
+In the second synopsis form,
+.Nm
+will print information about all supported options and their purpose.
+.Pp
+The following options are available:
+.Bl -tag  -width XqualXvalueXX
+.It Fl h
+Shows a short summary of all available options and their purpose.
+.It Fl s Ar qual:value
+Analyzes termination status.
+Must be one of:
+.Bl -tag -width signal:<value> -compact
+.It Ar exit:<value>
+checks that the program exited cleanly and that its exit status is equal to
+.Va value .
+The exit code can be omitted altogether, in which case any clean exit is
+accepted.
+.It Ar ignore
+ignores the exit check.
+.It Ar signal:<value>
+checks that the program exited due to a signal and that the signal that
+terminated it is
+.Va value .
+The signal can be specified both as a number or as a name, or it can also
+be omitted altogether, in which case any signal is accepted.
+.El
+.Pp
+Most of these checkers can be prefixed by the
+.Sq not-
+string, which effectively reverses the check.
+.It Fl o Ar action:arg
+Analyzes standard output.
+Must be one of:
+.Bl -tag -width inline:<value> -compact
+.It Ar empty
+checks that stdout is empty
+.It Ar ignore
+ignores stdout
+.It Ar file:<path>
+compares stdout with given file
+.It Ar inline:<value>
+compares stdout with inline value
+.It Ar match:<regexp>
+looks for a regular expression in stdout
+.It Ar save:<path>
+saves stdout to given file
+.El
+.Pp
+Most of these checkers can be prefixed by the
+.Sq not-
+string, which effectively reverses the check.
+.It Fl e Ar action:arg
+Analyzes standard error (syntax identical to above)
+.It Fl x
+Executes
+.Ar command
+as a shell command line, executing it with the system shell defined by
+.Va ATF_SHELL
+in
+.Xr atf-config 1 .
+You should avoid using this flag if at all possible to prevent shell quoting
+issues.
+.El
+.Sh EXIT STATUS
+.Nm
+exits 0 on success, and other (unspecified) value on failure.
+.Sh EXAMPLES
+.Bd -literal -offset indent
+# Exit code 0, nothing on stdout/stderr
+atf-check 'true'
+
+# Typical usage if failure is expected
+atf-check -s not-exit:0 'false'
+
+# Checking stdout/stderr
+echo foobar >expout
+atf-check -o file:expout -e inline:"xx\etyy\en" \e
+    'echo foobar ; printf "xx\etyy\en" >&2'
+
+# Checking for a crash
+atf-check -s signal:sigsegv my_program
+
+# Combined checks
+atf-check -o match:foo -o not-match:bar echo foo baz

+.Sh DESCRIPTION
+ATF
+provides a simple but powerful interface to easily write test programs in
+the POSIX shell language.
+These are extremely helpful given that they are trivial to write due to the
+language simplicity and the great deal of available external tools, so they
+are often ideal to test other applications at the user level.
+.Pp
+Test programs written using this library must be run using the
+.Xr atf-sh 1
+interpreter by putting the following on their very first line:
+.Bd -literal -offset indent
+#! /usr/bin/env atf-sh
+.Ed
+.Pp
+Shell-based test programs always follow this template:
+.Bd -literal -offset indent
+atf_test_case tc1
+tc1_head() {
+    ... first test case's header ...
+}
+tc1_body() {
+    ... first test case's body ...
+}
+
+atf_test_case tc2 cleanup
+tc2_head() {
+    ... second test case's header ...
+}
+tc2_body() {
+    ... second test case's body ...
+}
+tc2_cleanup() {
+    ... second test case's cleanup ...
+}
+
+.Ns ... additional test cases ...
+
+atf_init_test_cases() {
+    atf_add_test_case tc1
+    atf_add_test_case tc2
+    ... add additional test cases ...
+}
+.Ed
+.Ss Definition of test cases
+Test cases have an identifier and are composed of three different parts:
+the header, the body and an optional cleanup routine, all of which are
+described in
+.Xr atf-test-case 4 .
+To define test cases, one can use the
+.Fn atf_test_case
+function, which takes a first parameter specifiying the test case's
+name and instructs the library to set things up to accept it as a valid
+test case.
+The second parameter is optional and, if provided, must be
+.Sq cleanup ;
+providing this parameter allows defining a cleanup routine for the test
+case.
+It is important to note that this function
+.Em does not
+set the test case up for execution when the program is run.
+In order to do so, a later registration is needed through the
+.Fn atf_add_test_case
+function detailed in
+.Sx Program initialization .
+.Pp
+Later on, one must define the three parts of the body by providing two
+or three functions (remember that the cleanup routine is optional).
+These functions are named after the test case's identifier, and are
+.Fn <id>_head ,
+.Fn <id>_body
+and
+.Fn <id>_cleanup.
+None of these take parameters when executed.
+.Ss Program initialization
+The test program must define an
+.Fn atf_init_test_cases
+function, which is in charge of registering the test cases that will be
+executed at run time by using the
+.Fn atf_add_test_case
+function, which takes the name of a test case as its single parameter.
+This main function should not do anything else, except maybe sourcing
+auxiliary source files that define extra variables and functions.
+.Ss Configuration variables
+The test case has read-only access to the current configuration variables
+through the
+.Fn atf_config_has
+and
+.Fn atf_config_get
+methods.
+The former takes a single parameter specifying a variable name and returns
+a boolean indicating whether the variable is defined or not.
+The latter can take one or two parameters.
+If it takes only one, it specifies the variable from which to get the
+value, and this variable must be defined.
+If it takes two, the second one specifies a default value to be returned
+if the variable is not available.
+.Ss Access to the source directory
+It is possible to get the path to the test case's source directory from
+anywhere in the test program by using the
+.Fn atf_get_srcdir
+function.
+It is interesting to note that this can be used inside
+.Fn atf_init_test_cases
+to silently include additional helper files from the source directory.
+.Ss Requiring programs
+Aside from the
+.Va require.progs
+meta-data variable available in the header only, one can also check for
+additional programs in the test case's body by using the
+.Fn atf_require_prog
+function, which takes the base name or full path of a single binary.
+Relative paths are forbidden.
+If it is not found, the test case will be automatically skipped.
+.Ss Test case finalization
+The test case finalizes either when the body reaches its end, at which
+point the test is assumed to have
+.Em passed ,
+or at any explicit call to
+.Fn atf_pass ,
+.Fn atf_fail
+or
+.Fn atf_skip .
+These three functions terminate the execution of the test case immediately.
+The cleanup routine will be processed afterwards in a completely automated
+way, regardless of the test case's termination reason.
+.Pp
+.Fn atf_pass
+does not take any parameters.
+.Fn atf_fail
+and
+.Fn atf_skip
+take a single string parameter that describes why the test case failed or
+was skipped, respectively.
+It is very important to provide a clear error message in both cases so that
+the user can quickly know why the test did not pass.
+.Ss Expectations
+Everything explained in the previous section changes when the test case
+expectations are redefined by the programmer.
+.Pp
+Each test case has an internal state called
+.Sq expect
+that describes what the test case expectations are at any point in time.
+The value of this property can change during execution by any of:
+.Bl -tag -width indent
+.It Fn atf_expect_death "reason" "..."
+Expects the test case to exit prematurely regardless of the nature of the
+exit.
+.It Fn atf_expect_exit "exitcode" "reason" "..."
+Expects the test case to exit cleanly.
+If
+.Va exitcode
+is not
+.Sq -1 ,
+.Xr atf-run 1
+will validate that the exit code of the test case matches the one provided
+in this call.
+Otherwise, the exact value will be ignored.
+.It Fn atf_expect_fail "reason"
+Any failure raised in this mode is recorded, but such failures do not report
+the test case as failed; instead, the test case finalizes cleanly and is
+reported as
+.Sq expected failure ;
+this report includes the provided
+.Fa reason
+as part of it.
+If no error is raised while running in this mode, then the test case is
+reported as
+.Sq failed .
+.Pp
+This mode is useful to reproduce actual known bugs in tests.
+Whenever the developer fixes the bug later on, the test case will start
+reporting a failure, signaling the developer that the test case must be
+adjusted to the new conditions.
+In this situation, it is useful, for example, to set
+.Fa reason
+as the bug number for tracking purposes.
+.It Fn atf_expect_pass
+This is the normal mode of execution.
+In this mode, any failure is reported as such to the user and the test case
+is marked as
+.Sq failed .
+.It Fn atf_expect_signal "signo" "reason" "..."
+Expects the test case to terminate due to the reception of a signal.
+If
+.Va signo
+is not
+.Sq -1 ,
+.Xr atf-run 1
+will validate that the signal that terminated the test case matches the one
+provided in this call.
+Otherwise, the exact value will be ignored.
+.It Fn atf_expect_timeout "reason" "..."
+Expects the test case to execute for longer than its timeout.
+.El
+.Ss Helper functions for common checks
+.Fn atf_check [options] command [args]
+.Pp
+This function wraps the execution of the
+.Nm atf-check
+tool and makes the test case fail if the tool reports failure.
+You should always use this function instead of the tool in your scripts.
+For more details on the parameters of this function, refer to
+.Xr atf-check 1 .
+.Pp
+.Fn atf_check_equal expr1 expr2
+.Pp
+This function takes two expressions, evaluates them and, if their
+results differ, aborts the test case with an appropriate failure message.
+.Sh EXAMPLES
+The following shows a complete test program with a single test case that
+validates the addition operator:
+.Bd -literal -offset indent
+atf_test_case addition
+addition_head() {
+    atf_set "descr" "Sample tests for the addition operator"
+}
+addition_body() {
+    atf_check_equal $((0 + 0)) 0
+    atf_check_equal $((0 + 1)) 1
+    atf_check_equal $((1 + 0)) 0
+
+    atf_check_equal $((1 + 1)) 2
+
+    atf_check_equal $((100 + 200)) 300
+}
+
+atf_init_test_cases() {
+    atf_add_test_case addition
+}
+.Ed
+.Pp
+This other example shows how to include a file with extra helper functions
+in the test program:
+.Bd -literal -offset indent
+.Ns ... definition of test cases ...
+
+atf_init_test_cases() {
+    . $(atf_get_srcdir)/helper_functions.sh
+
+    atf_add_test_case foo1
+    atf_add_test_case foo2
+}
+.Ed
+.Pp
+This example demonstrates the use of the very useful
+.Fn atf_check
+function:
+.Bd -literal -offset indent
+# Check for silent output
+atf_check 'true' 0 null null
+
+# Check for silent output and failure
+atf_check 'false' 1 null null
+
+# Check for known stdout and silent stderr
+echo foo >expout
+atf_check 'echo foo' 0 expout null
+
+# Generate a file for later inspection
+atf_check 'ls' 0 stdout null
+grep foo ls || atf_fail "foo file not found in listing"

+\`configure' configures Automated Testing Framework 0.16 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+.Os
+.Sh NAME
+.Nm atf-formats
+.Nd machine-parseable data formats used by ATF
+.Sh DESCRIPTION
+This manual page describes the multiple data formats used in ATF.
+These formats affect configuration files, control files and any data that
+is externalized or internalized by the tools.
+.Pp
+Data files are always organized as follows:
+.Bd -literal -offset indent
+Header1: Value1            \\
+    ...                    | head
+HeaderN: ValueN            /
+                           mandatory blank line
+Free-form text contents    \\
+    ...                    | body
+    ...                    /
+.Ed
+.Pp
+A file must always contain a
+.Sq Content-Type
+header and must always separate that header from the body with a blank
+line, even if the body is empty.
+.Pp
+The
+.Sq Content-Type
+is always of the form:
+.Bd -literal -offset indent
+Content-Type: application/X-atf-<subtype>; version="<version>"
+.Ed
+.Pp
+where
+.Sq subtype
+indicates the specific file format and
+.Sq version
+its format version.
+This header must be the first one of the file.
+.Pp
+The main purpose of the
+.Sq Content-Type
+header, aside from determining the format used in the file, is to allow
+future changes to a given format.
+Whenever an incompatible change is made, the version is bumped by one.
+By keeping the header in the first line, future versions may even remove
+the need for such a header -- e.g. if some format was replaced by XML
+files, which have their own mandatory header.
+.Pp
+The rest of this document details the different format types.
+.Ss Format: application/X-atf-atffile, version: 1
+Atffiles are logically divided into three sections:
+.Bl -bullet
+.It
+Test programs: the list of test programs that define the test suite
+described by the Atffile.
+.It
+Meta-data properties: these define some constant values applicable to
+all the test programs defined in the file.
+In some sense they define the properties that describe the test suite.
+.It
+Configuration variables: defaults for configuration variables that
+can be overridden through configuration files or the command line.
+.El
+.Pp
+The grammar for Atffiles is the following:
+.Bd -literal -offset indent
+DATA ::= ( ( CONF | PROP | TP )? COMMENT? NEWLINE )* EOF
+CONF ::= 'conf:' WORD EQUAL STRING
+PROP ::= 'prop:' WORD EQUAL STRING
+TP ::= TPFILE | TPGLOB
+TPFILE ::= 'tp: ' STRING
+TPGLOB ::= 'tp-glob: ' STRING
+STRING ::= WORD | '"' WORD* '"'
+.Ed
+.Pp
+The meaning of the constructions above is:
+.Bl -tag -width TPGLOBXX
+.It CONF
+Definition of a configuration variable.
+.It PROP
+Definition of a meta-data property.
+.It TPFILE
+Addition of a test program into the test suite.
+The string is taken literally as the program's name, and this program
+must exist.
+.It TPGLOB
+Addition of multiple test programs into the test suite.
+The string is taken as a glob pattern, which may have or not have any
+matches in the current directory.
+.El
+.Pp
+An example:
+.Bd -literal -offset indent
+prop: test-suite = utilities
+
+conf: unprivileged-user = nobody
+
+tp: t_cp
+tp: t_mv
+tp: t_df
+tp-glob: t_dir_*
+.Ed
+.Ss Format: application/X-atf-config, version: 1
+Configuration files are very simple: they only contain a list of variable
+name/variable value pairs.
+Their grammar is:
+.Bd -literal -offset indent
+DATA ::= ( VAR? COMMENT? NEWLINE )* EOF
+VAR ::= WORD EQUAL STRING
+COMMENT ::= HASH WORD*
+STRING ::= WORD | '"' WORD* '"'
+.Ed
+.Pp
+An example:
+.Bd -literal -offset indent
+# This is the system-wide configuration file for ATF.
+# The above and this line are comments placed on their own line.
+
+var1 = this is a variable value
+var2 = this is another one      # Optional comment at the end.
+.Ed
+.Ss Format: application/X-atf-tps, version: 3
+The
+.Sq application/X-atf-tps
+format multiplexes the standard output, standard error and results output
+streams from multiple test programs into a single data file.
+This format is used by
+.Xr atf-run 1
+to report the execution of several test programs and is later parsed by
+.Xr atf-report 1
+to inform the user of this process.
+It has the following grammar:
+.Bd -literal -offset indent
+DATA ::= INFO* TPS-COUNT TP-STANZA* INFO* EOF
+INFO ::= 'info' COLON STRING COMMA STRING NEWLINE
+TPS-COUNT ::= 'tps-count' COLON POSITIVE-NUMBER NEWLINE
+TP-STANZA ::= TP-START TC-STANZA* TC-END
+TP-START ::= 'tp-start' COLON TIMESTAMP COMMA STRING COMMA
+             POSITIVE-NUMBER NEWLINE
+TP-END ::= 'tc-end' COLON TIMESTAMP COMMA STRING (COMMA STRING)?
+TC-STANZA ::= TC-START (TC-SO | TC-SE)* TC-END
+TC-START ::= 'tc-start' COLON TIMESTAMP COMMA STRING NEWLINE
+TC-SO ::= 'tc-so' COLON STRING NEWLINE
+TC-SE ::= 'tc-se' COLON STRING NEWLINE
+TC-END ::= 'tc-end' COLON TIMESTAMP COMMA STRING COMMA TCR NEWLINE
+TCR ::= 'passed' | ('failed' | 'skipped') COMMA STRING
+TIMESTAMP ::= [0-9]+.[0-9]+
+.Ed
+.Pp
+The meaning of the constructions above is:
+.Bl -tag -width TPSXCOUNTXX
+.It TPS-COUNT
+Indicates the number of test programs that will be executed.
+There will be this exact amount of
+.Sq TP-STANZA
+constructions following it.
+.It TP-START
+Indicates the beginning of a test program.
+This includes the program's name and the amount of test cases that
+will follow.
+.It TP-END
+Indicates the completion of a test program.
+This is followed by the program's name and, if the program ended
+prematurely, an error message indicating the reason of its failure.
+A successful execution of a test program (regardless of the status of its
+test cases) must not be accompanied by any reason.
+.It TC-START
+Indicates the beginning of a test case.
+This is accompanied by the test case's name.
+.It TC-SO
+Contains a text line sent to the standard output stream during the
+execution of the test case.
+Leading and trailing space is preserved.
+.It TC-SE
+Contains a text line sent to the standard error stream during the
+execution of the test case.
+Leading and trailing space is preserved.
+.It TC-END
+Indicates the completion of a test case.
+This is accompanied by the test case's name, its result and the reason
+associated with this result (if applicable).
+.El
+.Pp
+An example:
+.Bd -literal -offset indent
+tps-count: 2
+tp-start: calculator, 1324318951.838923, 2
+tc-start: add, 1324318951.839101
+tc-end: add, 1324318951.839500, passed
+tc-start: subtract, 1324318951.840001
+tc-so: 3-2 expected to return 1 but got 0
+tc-end: subtract, 1324318952.000123, failed, Calculated an unexpected value
+tp-end: calculator, 1324318952.002301
+tp-start: files, 1, 1324318952.502348
+tc-start: copy, 1324318952.508291

+.Dt ATF-TEST-CASE 4
+.Os
+.Sh NAME
+.Nm atf-test-case
+.Nd generic description of test cases
+.Sh DESCRIPTION
+A
+.Em test case
+is a piece of code that stress-tests a specific feature of the software.
+This feature is typically self-contained enough, either in the amount of
+code that implements it or in the general idea that describes it, to
+warrant its independent testing.
+Given this, test cases are very fine-grained, but they attempt to group
+similar smaller tests which are semantically related.
+.Pp
+A test case is defined by three components regardless of the language it is
+implemented in: a header, a body and a cleanup routine.
+The
+.Em header
+is, basically, a declarative piece of code that defines several
+properties to describe what the test case does and how it behaves.
+In other words: it defines the test case's
+.Em meta-data ,
+further described in the
+.Sx Meta-data
+section.
+The
+.Em body
+is the test case itself.
+It executes all actions needed to reproduce the test, and checks for
+failures.
+This body is only executed if the abstract conditions specified by the
+header are met.
+The
+.Em cleanup routine
+routine is a piece of code always executed after the body, regardless of
+the exit status of the test case.
+It can be used to undo side-effects of the test case.
+Note that almost all side-effects of a test case are automatically cleaned
+up by the library; this is explained in more detail in the rest of this
+document.
+.Pp
+It is extremely important to keep the separation between a test case's
+header and body well-defined, because the header is
+.Em always
+parsed, whereas the body is only executed when the conditions defined in
+the header are met and when the user specifies that test case.
+.Pp
+At last, test cases are always contained into test programs.
+The test programs act as a front-end to them, providing a consistent
+interface to the user and several APIs to ease their implementation.
+.Ss Results
+Upon termination, a test case reports a status and, optionally, a textual
+reason describing why the test reported such status.
+The caller must ensure that the test case really performed the task that its
+status describes, as the test program may be bogus and therefore providing a
+misleading result (e.g. providing a result that indicates success but the
+error code of the program says otherwise).
+.Pp
+The possible exit status of a test case are one of the following:
+.Bl -tag -width expectedXfailureXX
+.It expected_death
+The test case expects to terminate abruptly.
+.It expected_exit
+The test case expects to exit cleanly.
+.It expected_failure
+The test case expects to exit with a controller fatal/non-fatal failure.
+If this happens, the test program exits with a success error code.
+.It expected_signal
+The test case expects to receive a signal that makes it terminate.
+.It expected_timeout
+The test case expects to execute for longer than its timeout.
+.It passed
+The test case was executed successfully.
+The test program exits with a success error code.
+.It skipped
+The test case could not be executed because some preconditions were not
+met.
+This is not a failure because it can typically be resolved by adjusting
+the system to meet the necessary conditions.
+This is always accompanied by a
+.Em reason ,
+a message describing why the test was skipped.
+The test program exits with a success error code.
+.It failed
+An error appeared during the execution of the test case.
+This is always accompanied by a
+.Em reason ,
+a message describing why the test failed.
+The test program exits with a failure error code.
+.El
+.Pp
+The usefulness of the
+.Sq expected_*
+results comes when writing test cases that verify known failures caused,
+in general, due to programming errors (aka bugs).
+Whenever the faulty condition that the expectation is trying to convery is
+fixed, then the test case will be reported as
+.Sq failed
+and the developer will have to adjust it to match its new condition.
+.Pp
+It is important to note that all
+.Sq expected_*
+results are only provided as a
+.Em hint
+to the caller; the caller must verify that the test case did actually terminate
+as the expected condition says.
+.Ss Input/output
+Test cases are free to print whatever they want to their
+.Xr stdout 4
+and
+.Xr stderr 4
+file descriptors.
+They are, in fact, encouraged to print status information as they execute
+to keep the user informed of their actions.
+This is specially important for long test cases.
+.Pp
+Test cases will log their results to an auxiliary file, which is then
+collected by the test program they are contained in.
+The developer need not care about this as long as he uses the correct
+APIs to implement the test cases.
+.Pp
+The standard input of the test cases is unconditionally connected to
+.Sq /dev/zero .
+.Ss Meta-data
+The following list describes all meta-data properties interpreted
+internally by ATF.
+You are free to define new properties in your test cases and use them as
+you wish, but non-standard properties must be prefixed by
+.Sq X- .
+.Bl -tag -width requireXmachineXX
+.It descr
+Type: textual.
+Required.
+.Pp
+A brief textual description of the test case's purpose.
+Will be shown to the user in reports.
+Also good for documentation purposes.
+.It has.cleanup
+Type: boolean.
+Optional.
+.Pp
+If set to true, specifies that the test case has a cleanup routine that has
+to be executed by
+.Xr atf-run 1
+during the cleanup phase of the execution.
+This property is automatically set by the framework when defining a test case
+with a cleanup routine, so it should never be set by hand.
+.It ident
+Type: textual.
+Required.
+.Pp
+The test case's identifier.
+Must be unique inside the test program and should be short but descriptive.
+.It require.arch
+Type: textual.
+Optional.
+.Pp
+A whitespace separated list of architectures that the test case can be run
+under without causing errors due to an architecture mismatch.
+.It require.config
+Type: textual.
+Optional.
+.Pp
+A whitespace separated list of configuration variables that must be defined
+to execute the test case.
+If any of the required variables is not defined, the test case is
+.Em skipped .
+.It require.files
+Type: textual.
+Optional.
+.Pp
+A whitespace separated list of files that must be present to execute the
+test case.
+The names of these files must be absolute paths.
+If any of the required files is not found, the test case is
+.Em skipped .
+.It require.machine
+Type: textual.
+Optional.
+.Pp
+A whitespace separated list of machine types that the test case can be run
+under without causing errors due to a machine type mismatch.
+.It require.memory
+Type: integer.
+Optional.
+Specifies the minimum amount of physical memory needed by the test.
+The value can have a size suffix such as
+.Sq K ,
+.Sq M ,
+.Sq G
+or
+.Sq T
+to make the amount of bytes easier to type and read.
+.It require.progs
+Type: textual.
+Optional.
+.Pp
+A whitespace separated list of programs that must be present to execute
+the test case.
+These can be given as plain names, in which case they are looked in the
+user's
+.Ev PATH ,
+or as absolute paths.
+If any of the required programs is not found, the test case is
+.Em skipped .
+.It require.user
+Type: textual.
+Optional.
+.Pp
+The required privileges to execute the test case.
+Can be one of
+.Sq root
+or
+.Sq unprivileged .
+.Pp
+If the test case is running as a regular user and this property is
+.Sq root ,
+the test case is
+.Em skipped .
+.Pp
+If the test case is running as root and this property is
+.Sq unprivileged ,
+.Xr atf-run 1
+will automatically drop the privileges if the
+.Sq unprivileged-user
+configuration property is set; otherwise the test case is
+.Em skipped .
+.It timeout
+Type: integral.
+Optional; defaults to
+.Sq 300 .
+.Pp
+Specifies the maximum amount of time the test case can run.
+This is particularly useful because some tests can stall either because they
+are incorrectly coded or because they trigger an anomalous behavior of the
+program.
+It is not acceptable for these tests to stall the whole execution of the
+test program.
+.Pp
+Can optionally be set to zero, in which case the test case has no run-time
+limit.
+This is discouraged.
+.El
+.Ss Environment
+Every time a test case is executed, several environment variables are
+cleared or reseted to sane values to ensure they do not make the test fail
+due to unexpected conditions.
+These variables are:
+.Bl -tag -width LCXMESSAGESXX
+.It Ev HOME
+Set to the work directory's path.
+.It Ev LANG
+Undefined.
+.It Ev LC_ALL
+Undefined.
+.It Ev LC_COLLATE
+Undefined.
+.It Ev LC_CTYPE
+Undefined.
+.It Ev LC_MESSAGES
+Undefined.
+.It Ev LC_MONETARY
+Undefined.
+.It Ev LC_NUMERIC
+Undefined.
+.It Ev LC_TIME
+Undefined.
+.It Ev TZ
+Hardcoded to
+.Sq UTC .
+.El
+.Ss Work directories
+The test program always creates a temporary directory
+and switches to it before running the test case's body.
+This way the test case is free to modify its current directory as it
+wishes, and the runtime engine will be able to clean it up later on in a
+safe way, removing any traces of its execution from the system.
+To do so, the runtime engine will perform a recursive removal of the work
+directory without crossing mount points; if a mount point is found, the
+file system will be unmounted (if possible).
+.Ss File creation mode mask (umask)
+Test cases are always executed with a file creation mode mask (umask) of
+.Sq 0022 .

+.Sh DESCRIPTION
+Test programs written using the ATF libraries all share a common user
+interface, which is what this manual page describes.
+.Em NOTE: There is no binary known as
+.Nm ;
+.Em what is described in this manual page is the command-line interface
+.Em exposed by the atf-c, atf-c++ and atf-sh bindings .
+.Pp
+In the first synopsis form, the test program will execute the provided
+test case and print its results to the standard output, unless otherwise
+stated by the
+.Fl r
+flag.
+Optionally, the test case name can be suffixed by
+.Sq :cleanup ,
+in which case the cleanup routine of the test case will be executed
+instead of the test case body; see
+.Xr atf-test-case 4 .
+Note that the test case is
+.Em executed without isolation ,
+so it can and probably will create and modify files in the current directory.
+To execute test cases in a controller manner, refer to
+.Xr atf-run 1 ,
+which is the preferred way to run test cases.
+You should only execute test cases by hand for debugging purposes.
+.Pp
+In the second synopsis form, the test program will list all available
+test cases alongside their meta-data properties in a format that is
+machine parseable.
+This list is processed by
+.Xr atf-run 1
+to know how to execute the test cases of a given test program.
+.Pp
+The following options are available:
+.Bl -tag -width XvXvarXvalueXX
+.It Fl l
+Lists available test cases alongside a brief description for each of them.
+.It Fl r Ar resfile
+Specifies the file that will receive the test case result.
+If not specified, the test case prints its results to stdout.
+If the result of a test case needs to be parsed by another program, you must
+use this option to redirect the result to a file and then read the resulting
+file from the other program.
+Note:
+.Em do not try to process the stdout of the test case
+because your program may break in the future.
+.It Fl s Ar srcdir
+The path to the directory where the test program is located.
+This is needed in all cases, except when the test program is being executed
+from the current directory.
+The test program will use this path to locate any helper data files or
+utilities.
+.It Fl v Ar var=value
+Sets the configuration variable
+.Ar var
+to the value
+.Ar value .

+.Nd introduction to the Automated Testing Framework
+.Sh DESCRIPTION
+.Em IMPORTANT: If you are here because you want to know how to run the tests in
+.Em Pa __TESTSDIR__ ,
+.Em you most likely want to read the
+.Em Xr tests 7
+.Em manual page instead.
+.Pp
+The Automated Testing Framework
+.Pf ( Nm )
+is a collection of libraries and utilities designed to ease unattended
+application testing in the hands of developers and end users of a specific
+piece of software.
+.Pp
+As regards developers,
+.Nm
+provides the necessary means to easily create
+test suites composed of multiple test programs, which in turn are a
+collection of test cases.
+It also attempts to simplify the debugging of problems when these test
+cases detect an error by providing as much information as possible
+about the failure.
+.Pp
+As regards users, it simplifies the process of running the test suites and,
+in special, encourages end users to run them often: they do not need to
+have source trees around nor any other development tools installed to be
+able to certify that a given piece of software works on their machine as
+advertised.
+.Pp
+If your operating systems distributes
+.Nm ,
+it is possible that it provides an introductory
+.Xr tests 7
+manual page.
+You are encouraged to read it now.

+.Ss Components
+.Nm
+is a highly modular piece of software.
+It provides a couple of libraries to ease the implementation of test
+programs: one for the C and C++ languages and another one for shell
+scripts.
+It also includes multiple small utilities that follow the principle of
+doing a single thing but doing it right.
+This section outlines which these components are.
+.Pp
+Public utilities:
+.Bl -tag -width atfXtestXprogramXXXXX
+.It Xr atf-check 1
+Executes a command and checks that its exit code, its standard output
+and its standard error output match pre-specified expected values.
+.It Xr atf-config 1
+Queries static configuration information.
+.It Xr atf-report 1
+Converts the output of
+.Nm atf-run
+to user-friendly and/or machine-parseable reports.
+.It Xr atf-run 1
+Automates the execution of a series of test programs and collects their
+results in a unified report.
+.It Xr atf-sh 1
+Shell interpreter for shell-based test programs.

+dnl Macros to check for the existence of compiler flags.  The macros in this
+dnl file support both C and C++.
+dnl
+dnl Be aware that, in order to detect a flag accurately, we may need to enable
+dnl strict warning checking in the compiler (i.e. enable -Werror).  Some
+dnl compilers, e.g. Clang, report unknown -W flags as warnings unless -Werror is
+dnl selected.  This fact would confuse the flag checks below because we would
+dnl conclude that a flag is valid while in reality it is not.  To resolve this,
+dnl the macros below will pass -Werror to the compiler along with any other flag
+dnl being checked.

+dnl \param 5 Additional, optional flags to pass to the C compiler while

+dnl
+dnl "Developer mode" is a mode in which the build system reports any
+dnl build-time warnings as fatal errors.  This helps in minimizing the
+dnl amount of trivial coding problems introduced in the code.
+dnl Unfortunately, this is not bullet-proof due to the wide variety of
+dnl compilers available and their different warning diagnostics.
+dnl
+dnl When developer mode support is added to a package, the compilation will
+dnl gain a bunch of extra warning diagnostics.  These will NOT be enforced
+dnl unless developer mode is enabled.
+dnl
+dnl Developer mode is enabled when the user requests it through the
+dnl configure command line, or when building from the repository.  The
+dnl latter is to minimize the risk of committing new code with warnings
+dnl into the tree.
+
+
+dnl Adds "developer mode" support to the package.
