+This document details the changes between this version, readline-4.3,
+and the previous version, readline-4.2a.
+
+1.  Changes to Readline
+
+a.  Fixed output of comment-begin character when listing variable values.
+
+b.  Added some default key bindings for common escape sequences produced by
+    HOME and END keys.
+
+c.  Fixed the mark handling code to be more emacs-compatible.
+
+d.  A bug was fixed in the code that prints possible completions to keep it
+    from printing empty strings in certain circumstances.
+
+e.  Change the key sequence printing code to print ESC as M\- if ESC is a
+    meta-prefix character -- it's easier for users to understand than \e.
+
+f.  Fixed unstifle_history() to return values that match the documentation.
+
+g.  Fixed the event loop (rl_event_hook) to handle the case where the input
+    file descriptor is invalidated.
+
+h.  Fixed the prompt display code to work better when the application has a
+    custom redisplay function.
+
+i.  Changes to make reading and writing the history file a little faster, and
+    to cope with huge history files without calling abort(3) from xmalloc.
+
+j.  The vi-mode `S' and `s' commands are now undone correctly.
+
+k.  Fixed a problem which caused the display to be messed up when the last
+    line of a multi-line prompt (possibly containing invisible characters)
+    was longer than the screen width.
+
+2.  New Features in Readline
+
+a.  Support for key `subsequences':  allows, e.g., ESC and ESC-a to both
+    be bound to readline functions.  Now the arrow keys may be used in vi
+    insert mode.
+
+b.  When listing completions, and the number of lines displayed is more than
+    the screen length, readline uses an internal pager to display the results.
+    This is controlled by the `page-completions' variable (default on).
+
+c.  New code to handle editing and displaying multibyte characters.
+
+d.  The behavior introduced in bash-2.05a of deciding whether or not to
+    append a slash to a completed name that is a symlink to a directory has
+    been made optional, controlled by the `mark-symlinked-directories'
+    variable (default is the 2.05a behavior).
+
+e.  The `insert-comment' command now acts as a toggle if given a numeric
+    argument:  if the first characters on the line don't specify a
+    comment, insert one; if they do, delete the comment text
+
+f.  New application-settable completion variable:
+    rl_completion_mark_symlink_dirs, allows an application's completion
+    function to temporarily override the user's preference for appending
+    slashes to names which are symlinks to directories.
+
+g.  New function available to application completion functions:
+    rl_completion_mode, to tell how the completion function was invoked
+    and decide which argument to supply to rl_complete_internal (to list
+    completions, etc.).
+
+h.  Readline now has an overwrite mode, toggled by the `overwrite-mode'
+    bindable command, which could be bound to `Insert'.
+
+i.  New application-settable completion variable:
+    rl_completion_suppress_append, inhibits appending of
+    rl_completion_append_character to completed words.
+
+j.  New key bindings when reading an incremental search string:  ^W yanks
+    the currently-matched word out of the current line into the search
+    string; ^Y yanks the rest of the current line into the search string,
+    DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.2a,
+and the previous version, readline-4.2.
+
+1.  Changes to Readline
+
+a.  More `const' and type casting fixes.
+
+b.  Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
+    overflow problems.
+
+c.  The completion code no longer appends a `/' or ` ' to a match when
+    completing a symbolic link that resolves to a directory name, unless
+    the match does not add anything to the word being completed.  This
+    means that a tab will complete the word up to the full name, but not
+    add anything, and a subsequent tab will add a slash.
+
+d.  Fixed a trivial typo that made the vi-mode `dT' command not work.
+
+e.  Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
+
+f.  Fixed the tty code so that ^V works more than once.
+
+g.  Changed the use of __P((...)) for function prototypes to PARAMS((...))
+    because the use of __P in typedefs conflicted g++ and glibc.
+
+h.  The completion code now attempts to do a better job of preserving the
+    case of the word the user typed if ignoring case in completions.
+
+i.  Readline defaults to not echoing the input and lets the terminal
+    initialization code enable echoing if there is a controlling terminal.
+
+j.  The key binding code now processes only two hex digits after a `\x'
+    escape sequence, and the documentation was changed to note that the
+    octal and hex escape sequences result in an eight-bit value rather
+    than strict ASCII.
+
+k.  Fixed a few places where negative array subscripts could have occurred.
+    
+l.  Fixed the vi-mode code to use a better method to determine the bounds of
+    the array used to hold the marks, and to avoid out-of-bounds references.
+    
+m.  Fixed the defines in chardefs.h to work better when chars are signed.
+    
+n.  Fixed configure.in to use the new names for bash autoconf macros.
+    
+o.  Readline no longer attempts to define its own versions of some ctype
+    macros if they are implemented as functions in libc but not as macros in
+    <ctype.h>.
+
+p.  Fixed a problem where rl_backward could possibly set point to before
+    the beginning of the line.
+
+q.  Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
+    include file problems.
+
+2.  New Features in Readline
+
+a.  Added extern declaration for rl_get_termcap to readline.h, making it a
+    public function (it was always there, just not in readline.h).
+
+b.  New #defines in readline.h:  RL_READLINE_VERSION, currently 0x0402,
+    RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c.  New readline variable:  rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d.  New bindable boolean readline variable:  match-hidden-files.  Controls
+    completion of files beginning with a `.' (on Unix).  Enabled by default.
+
+e.  The history expansion code now allows any character to terminate a
+    `:first-' modifier, like csh.
+
+f.  The incremental search code remembers the last search string and uses
+    it if ^R^R is typed without a search string.
+
+h.  New bindable variable `history-preserve-point'.  If set, the history
+    code attempts to place the user at the same location on each history
+    line retrived with previous-history or next-history.
+

 Basic Installation

-those values to create a `Makefile' in each directory of the package.

+Some systems require unusual options for compilation or linking that

 Or on systems that have the `env' program, you can do it like this:

+reconfiguring for another architecture. 
 
 Installation Names
 ==================
 
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
+By default, `make install' will install the readline libraries in
+`/usr/local/lib', the include files in
+`/usr/local/include/readline', the man pages in `/usr/local/man',
+and the info files in `/usr/local/info'.  You can specify an
+installation prefix other than `/usr/local' by giving `configure'
+the option `--prefix=PATH' or by supplying a value for the
+DESTDIR variable when running `make install'. 
+
+You can specify separate installation prefixes for

+If you give `configure' the option `--exec-prefix=PATH', the
+readline Makefiles will use PATH as the prefix for installing the
+libraries.  Documentation and other data files will still use the
+regular prefix. 
 
 Specifying the System Type
 ==========================
 
-   There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on.  Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
-     CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.

+fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2). 
 
-   If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.

+Optional Features
+=================
+
+The readline `configure' recognizes a single `--with-PACKAGE' option:
+
+`--with-curses'
+    This tells readline that it can find the termcap library functions
+    (tgetent, et al.) in the curses library, rather than a separate
+    termcap library.  Readline uses the termcap functions, but does not
+    link with the termcap or curses library itself, allowing applications
+    which link with readline the to choose an appropriate library.
+    This option tells readline to link the example programs with the
+    curses library rather than libtermcap.
+
+`configure' also recognizes two `--enable-FEATURE' options:
+
+`--enable-shared'
+    Build the shared libraries by default on supported platforms.  The
+    default is `yes'.
+
+`--enable-static'
+    Build the static libraries by default.  The default is `yes'.
+ 
+Shared Libraries
+================
+
+There is support for building shared versions of the readline and
+history libraries.  The configure script creates a Makefile in
+the `shlib' subdirectory, and typing `make shared' will cause
+shared versions of the readline and history libraries to be built
+on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile.  If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler.  The script uses
+the value of host_os and ${CC} as determined by configure.  For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables.  They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files.  This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code.  If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.  If
+		shared libraries are not supported, this will be set to
+		`unsupported'.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared' or `make'.  The shared libraries will be created in the
+shlib subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory.  Running `make
+install' in the shlib subdirectory will also work.  If you don't want
+to install any created shared libraries, run `make install-static'.

+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 \`..']

+
+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'.
+
