 About mdocml, the portable mandoc distribution
 ----------------------------------------------
@@ -34,19 +34,52 @@ latest bundled and ported versions of mandoc for various operating
 systems is maintained at <http://mdocml.bsd.lv/ports.html>.
 
 If mandoc is installed, you can check the version by running "mandoc -V".
-The version contained in this distribution tarball is listed near
-the beginning of the file "Makefile".
+You can find the version contained in this distribution tarball
+by running "./configure".
 
 Regarding how packages and ports are maintained for your operating
 system, please consult your operating system documentation.
 To install mandoc manually, the following steps are needed:
 
-1. Decide whether you want to build the base tools mandoc(1),
-preconv(1) and demandoc(1) only or whether you also want to build the
-database tools apropos(1) and makewhatis(8).  For the latter,
-the following dependencies are required:
+1. If you want to build the CGI program, man.cgi(8), too, run the
+command "echo BUILD_CGI=1 > configure.local".  Then run "cp
+cgi.h.examples cgi.h" and edit cgi.h as desired.
 
-1.1. The SQLite database system, see <http://sqlite.org/>.
+2. Run "./configure".
+This script attempts autoconfiguration of mandoc for your system.
+Read both its standard output and the file "Makefile.local" it
+generates.  If anything looks wrong or different from what you
+wish, read the file "configure.local.example", create and edit
+a file "configure.local", and re-run "./configure" until the
+result seems right to you.
+
+3. Run "make".
+Any POSIX-compatible make, in particular both BSD make and GNU make,
+should work.  If the build fails, look at "configure.local.example"
+and go back to step 2.
+
+4. Run "make -n install" and check whether everything will be
+installed to the intended places.  Otherwise, put some *DIR variables
+into "configure.local" and go back to step�2.
+
+5. Run "sudo make install".  If you intend to build a binary
+package using some kind of fake root mechanism, you may need a
+command like "make DESTDIR=... install".  Read the *-install targets
+in the "Makefile" to understand how DESTDIR is used.
+
+6. To set up a man.cgi(8) server, read its manual page.
+
+7. To use mandoc(1) as your man(1) formatter, read the "Deployment"
+section below.

+Understanding mandoc dependencies
+---------------------------------
+The mandoc(1), preconv(1), and demandoc(1) utilities have no external
+dependencies.  However, makewhatis(8) and apropos(1) depend on the
+following software:
+
+1. The SQLite database system, see <http://sqlite.org/>.
 The recommended version of SQLite is 3.8.4.3 or newer.  The mandoc
 toolset is known to work with version 3.7.5 or newer.  Versions

 1.3. Marc Espie's ohash(3) library.

 will be used, so you probably need not worry about it.
 
-2. If you choose to build the database tools, too, decide whether
-you also want to build the CGI program, man.cgi(8).
-
-3. Read the beginning of the file "Makefile" from "USER SETTINGS"

-disable "BUILD_TARGETS += db-build" if you do not want database

-the CGI program.
-
-4. Run "make".  No separate "./configure" or "make depend" steps
-are needed.  The former is run automatically by "make".  The latter
-is a maintainer target.  If you merely want to build the released
-version as opposed to doing active development, there is no need
-to regenerate the dependency specifications.  Any POSIX-compatible
-make, in particular both BSD make and GNU make, should work.
-
-5. Run "make -n install" and check whether everything will be
-installed to the intended places.  Otherwise, edit the *DIR variables

     --- MAJOR NEW FEATURES ---
  * A complete apropos(1)/makewhatis(8)/man.cgi(8) suite
    based on SQLite3 is now included.
-   CAVEAT: This also requires a working fts(3) implementation.
-   If your system lacks that *and* you want apropos(1)/makewhatis(8),
-   stay with 1.12.3 for now, then go to 1.12.4 and 1.13.2.
  * The roff(7) parser now provides an almost complete implementation
    of numerical expressions.
  * Warning and error messages have been improved in many ways.

+
+# For -Tutf8 and -Tlocale operation, mandoc(1) requires <locale.h>
+# providing setlocale(3) and <wchar.h> providing wcwidth(3) and
+# putwchar(3) with a wchar_t storing UCS-4 values.  Theoretically,
+# the latter should be tested with the __STDC_ISO_10646__ feature
+# macro.  In practice, many <wchar.h> headers do not provide that
+# macro even though they treat wchar_t as UCS-4.  So the automatic
+# test only checks that wchar_t is wide enough, that is, at least
+# four bytes.
+
+# The following line forces multi-byte support.
+# If your C library does not treat wchar_t as UCS-4, the UTF-8 output
+# mode will print garbage.
+
+HAVE_WCHAR=1

+# The following line disables multi-byte support.
+# The output modes -Tutf8 and -Tlocale will be the same as -Tascii.

+# In manual pages written in the mdoc(7) language, the operating system

+# is specified as an argument to the .Os macro, that is always used.
+# If the .Os macro has no argument and an operation system is specified
+# with the mandoc(1) -Ios= command line option, that is used.
+# Otherwise, the uname(3) library function is called at runtime to find
+# the name of the operating system.
+# If you do not want uname(3) to be called but instead want a fixed
+# string to be used, use the following line:
+
+OSNAME="OpenBSD 5.5"

+# The following installation directories are used.

+The
+.Nm
+utility
+displays the
+manual pages entitled
+.Ar name .
+Pages may be selected according to
+a specific category
+.Pq Ar section
+or
+machine architecture
+.Pq Ar subsection .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl a
+Display all of the manual pages for a specified
+.Ar section
+and
+.Ar name
+combination.
+Normally, only the first manual page found is displayed.
+.It Fl C Ar file
+Use the specified
+.Ar file
+instead of the default configuration file.
+This permits users to configure their own manual environment.
+See
+.Xr man.conf 5
+for a description of the contents of this file.
+.It Fl c
+Copy the manual page to the standard output instead of using
+.Xr more 1
+to paginate it.
+This is done by default if the standard output is not a terminal device.
+.It Fl f
+A synonym for
+.Xr whatis 1 .
+It searches for
+.Ar name
+in manual page names and displays the header lines from all matching pages.
+The search is case insensitive and matches whole words only.
+This overrides any earlier
+.Fl k
+and
+.Fl l
+options.
+.It Fl h
+Display only the SYNOPSIS lines of the requested manual pages.
+Implies
+.Fl a
+and
+.Fl c .
+.It Fl k
+A synonym for
+.Xr apropos 1 .
+Instead of
+.Ar name ,
+an expression can be provided using the syntax described in the
+.Xr apropos 1
+manual.
+By default, it displays the header lines of all matching pages.
+This overrides any earlier
+.Fl f
+and
+.Fl l
+options.
+.It Fl l
+A synonym for
+.Xr mandoc 1
+.Fl a .
+The
+.Ar name
+arguments are interpreted as filenames.
+No search is done and
+.Ar file ,
+.Ar path ,
+.Ar section ,
+and
+.Ar subsection
+are ignored.
+This overrides any earlier
+.Fl f ,
+.Fl k ,
+and
+.Fl w
+options.
+.It Fl M Ar path
+Override the list of standard directories which
+.Nm
+searches for manual pages.
+The supplied
+.Ar path
+must be a colon
+.Pq Ql \&:
+separated list of directories.
+This search path may also be set using the environment variable
+.Ev MANPATH .
+The subdirectories to be searched, and their search order,
+are specified by the
+.Dq _subdir
+line in the
+.Nm
+configuration file.
+.It Fl m Ar path
+Augment the list of standard directories which
+.Nm
+searches for manual pages.
+The supplied
+.Ar path
+must be a colon
+.Pq Ql \&:
+separated list of directories.
+These directories will be searched before the standard directories or
+the directories specified using the
+.Fl M
+option or the
+.Ev MANPATH
+environment variable.
+The subdirectories to be searched, and their search order,
+are specified by the
+.Dq _subdir
+line in the
+.Nm
+configuration file.
+.It Fl S Ar subsection
+Restricts the directories that
+.Nm
+will search to those of a specific
+.Xr machine 1
+architecture.
+.Ar subsection
+is case insensitive.
+.Pp
+By default manual pages for all architectures are installed.
+Therefore this option can be used to view pages for one
+architecture whilst using another.
+.Pp
+This option overrides the
+.Ev MACHINE
+environment variable.
+.It Xo
+.Op Fl s
+.Ar section
+.Xc
+Restricts the directories that
+.Nm
+will search to a specific section.
+The currently available sections are:

+.Pp
+The
+.Nm
+configuration file,
+.Xr man.conf 5 ,
+specifies the possible
+.Ar section
+values, and their search order.
+Additional sections may be specified.
+.It Fl V
+Print version and exit.
+.It Fl w
+List the pathnames of the manual pages which
+.Nm
+would display for the specified
+.Ar section
+and
+.Ar name
+combination.
+.El
+.Pp
+The
+.Nm
+utility also supports the options
+.Fl IKOTW
+described in the
+.Xr mandoc 1
+manual.
+.Pp
+Guidelines for writing
+man pages can be found in
+.Xr mdoc 7 .
+.Pp
+If both a formatted and an unformatted version of the same manual page,
+for example
+.Pa cat1/foo.0
+and
+.Pa man1/foo.1 ,
+exist in the same directory, and at least one of them is selected,
+only the newer one is used.
+However, if both the
+.Fl a
+and the
+.Fl w
+options are specified, both file names are printed.
+.Sh ENVIRONMENT
+.Bl -tag -width MANPATHX
+.It Ev MACHINE
+As some manual pages are intended only for specific architectures,
+.Nm
+searches any subdirectories,
+with the same name as the current architecture,
+in every directory which it searches.
+Machine specific areas are checked before general areas.
+The current machine type may be overridden by setting the environment
+variable
+.Ev MACHINE
+to the name of a specific architecture,
+or with the
+.Fl S
+option.
+.Ev MACHINE
+is case insensitive.
+.It Ev MANPAGER
+Any non-empty value of the environment variable
+.Ev MANPAGER
+will be used instead of the standard pagination program,
+.Xr more 1 .
+.It Ev MANPATH
+The standard search path used by
+.Nm
+may be overridden by specifying a path in the
+.Ev MANPATH
+environment
+variable.
+The format of the path is a colon
+.Pq Ql \&:
+separated list of directories.
+The subdirectories to be searched, as well as their search order,
+are specified by the
+.Dq _subdir
+line in the
+.Nm
+configuration file.
+.It Ev PAGER
+Specifies the pagination program to use when
+.Ev MANPAGER
+is not defined.
+If neither PAGER nor MANPAGER is defined,
+.Pa /usr/bin/more Fl s
+will be used.

-.Dt PRECONV 1
-.Os
-.Sh NAME
-.Nm preconv
-.Nd recode multibyte UNIX manuals
-.Sh SYNOPSIS
-.Nm preconv
-.Op Fl D Ar enc
-.Op Fl e Ar enc
-.Op Ar file
-.Sh DESCRIPTION
-The
-.Nm
-utility recodes multibyte
-.Ux
-manual files into
-.Xr mandoc 1
-.Po
-or other troff system supporting the
-.Sq \e[uNNNN]
-escape sequence
-.Pc
-input.
-.Pp
-By default, it parses from standard output, determining encoding as
-described in
-.Sx Algorithm .
-.Pp
-Its arguments are as follows:
-.Bl -tag -width Ds
-.It Fl D Ar enc
-The default encoding.
-.It Fl e Ar enc
-The document's encoding.
-.It Ar file
-The input file.
-.El
-.Pp
-The recoded input is written to standard output: Unicode characters in
-the ASCII range are printed as regular ASCII characters, while those
-above this range are printed using the
-.Sq \e[uNNNN]
-format documented in
-.Xr mandoc_char 7 .
-.Pp
-If input bytes are improperly formed in the current encoding, they're
-passed unmodified to standard output.
-For some encodings, such as UTF-8, unrecoverable input sequences will
-cause
-.Nm
-to stop processing and exit.
-.Ss Algorithm
-An encoding is chosen according to the following steps:
-.Bl -enum
-.It
-From the argument passed to
-.Fl e Ar enc .
-.It
-If a BOM exists, UTF\-8 encoding is selected.
-.It
-From the coding tags parsed from
-.Qq File Variables
-on the first two lines of input.
-A file variable is an input line of the form
-.Pp
-.Dl \%.\e\(dq -*- key: val [; key: val ]* -*-
-.Pp
-A coding tag variable is where
-.Cm key
-is
-.Qq coding
-and
-.Cm val
-is the name of the encoding.
-A typical file variable with a coding tag is
-.Pp
-.Dl \%.\e\(dq -*- mode: troff; coding: utf-8 -*-
-.It
-From the argument passed to
-.Fl D Ar enc .
-.It
-If all else fails, Latin\-1 is used.
-.El
-.Pp
-The
-.Nm
-utility recognises the UTF\-8, us\-ascii, and latin\-1 encodings as
-passed to the
-.Fl e
-and
-.Fl D
-arguments, or as coding tags.
-Encodings are matched case-insensitively.

-.\" For sections 2, 3, & 9 only.
-.\" .Sh ENVIRONMENT
-.\" For sections 1, 6, 7, & 8 only.
-.\" .Sh FILES
-.Sh EXIT STATUS

-.\" .Sh DIAGNOSTICS
-.\" For sections 1, 4, 6, 7, & 8 only.
-.\" .Sh ERRORS
-.\" For sections 2, 3, & 9 only.
-.Sh SEE ALSO
-.Xr mandoc 1 ,
-.Xr mandoc_char 7
-.Sh STANDARDS
-The
-.Nm
-utility references the US-ASCII character set standard, ANSI_X3.4\-1968;
-the Latin\-1 character set standard, ISO/IEC 8859\-1:1998; the UTF\-8
-character set standard; and UCS (Unicode), ISO/IEC 10646.
-.Sh HISTORY
-The
-.Nm
-utility first appeared in the GNU troff
-.Pq Dq groff
-system in December 2005, authored by Tomohiro Kubota and Werner
-Lemberg.
-The implementation that is part of the
-.Xr mandoc 1
-utility appeared in May 2011.
