-This document details the changes between this version, readline-5.2,
-and the previous version, readline-5.1.
-
-1.  Changes to Readline
-
-a.  Fixed a problem that caused segmentation faults when using readline in
-    callback mode and typing consecutive DEL characters on an empty line.
-
-b.  Fixed several redisplay problems with multibyte characters, all having to
-    do with the different code paths and variable meanings between single-byte
-    and multibyte character redisplay.
-
-c.  Fixed a problem with key sequence translation when presented with the
-    sequence \M-\C-x.
-
-d.  Fixed a problem that prevented the `a' command in vi mode from being
-    undone and redone properly.
-
-e.  Fixed a problem that prevented empty inserts in vi mode from being undone
-    properly.
-
-f.  Fixed a problem that caused readline to initialize with an incorrect idea
-    of whether or not the terminal can autowrap.
-
-g.  Fixed output of key bindings (like bash `bind -p') to honor the setting of
-    convert-meta and use \e where appropriate.
-
-h.  Changed the default filename completion function to call the filename
-    dequoting function if the directory completion hook isn't set.  This means
-    that any directory completion hooks need to dequote the directory name,
-    since application-specific hooks need to know how the word was quoted,
-    even if no other changes are made.
-
-i.  Fixed a bug with creating the prompt for a non-interactive search string
-    when there are non-printing characters in the primary prompt.
-
-j.  Fixed a bug that caused prompts with invisible characters to be redrawn
-    multiple times in a multibyte locale.
-
-k.  Fixed a bug that could cause the key sequence scanning code to return the
-    wrong function.
-
-l.  Fixed a problem with the callback interface that caused it to fail when
-    using multi-character keyboard macros.
-
-m.  Fixed a bug that could cause a core dump when an edited history entry was
-    re-executed under certain conditions.
-
-n.  Fixed a bug that caused readline to reference freed memory when attmpting
-    to display a portion of the prompt.
-
-o.  Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
-    the prompt and input line multiple times.
-
-p.  Fixed history expansion to not be confused by here-string redirection.
-
-q.  Readline no longer treats read errors by converting them to newlines, as
-    it does with EOF.  This caused partial lines to be returned from readline().
-
-r.  Fixed a redisplay bug that occurred in multibyte-capable locales when the
-    prompt was one character longer than the screen width.
-
-2.  New Features in Readline
-
-a.  Calling applications can now set the keyboard timeout to 0, allowing
-    poll-like behavior.
-
-b.  The value of SYS_INPUTRC (configurable at compilation time) is now used as
-    the default last-ditch startup file.
-
-c.  The history file reading functions now allow windows-like \r\n line
-    terminators.
-
--------------------------------------------------------------------------------
-This document details the changes between this version, readline-5.1,
-and the previous version, readline-5.0.
-
-1.  Changes to Readline
-
-a.  Fixed a bug that caused multiliine prompts to be wrapped and displayed
-    incorrectly.
-
-b.  Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
-    line correctly.
-
-c.  Fixed a problem in computing the number of invisible characters on the first
-    line of a prompt whose length exceeds the screen width.
-
-d.  Fixed vi-mode searching so that failure preserves the current line rather
-    than the last line in the history list.
-
-e.  Fixed the vi-mode `~' command (change-case) to have the correct behavior at
-    end-of-line when manipulating multibyte characters.
-
-f.  Fixed the vi-mode `r' command (change-char) to have the correct behavior at
-    end-of-line when manipulating multibyte characters.
-
-g.  Fixed multiple bugs in the redisplay of multibyte characters:  displaying
-    prompts longer than the screen width containing multibyte characters,
-
-h.  Fix the calculation of the number of physical characters in the prompt
-    string when it contains multibyte characters.
-
-i.  A non-zero value for the `rl_complete_suppress_append' variable now causes
-    no `/' to be appended to a directory name.
-
-j.  Fixed forward-word and backward-word to work when words contained
-    multibyte characters.
-
-k.  Fixed a bug in finding the delimiter of a `?' substring when performing
-    history expansion in a locale that supports multibyte characters.
-
-l.  Fixed a memory leak caused by not freeing the timestamp in a history entry.
-
-m.  Fixed a bug that caused "\M-x" style key bindings to not obey the setting
-    of the `convert-meta' variable.
-
-n.  Fixed saving and restoring primary prompt when prompting for incremental   
-    and non-incremental searches; search prompts now display multibyte
-    characters correctly.
-
-o.  Fixed a bug that caused keys originally bound to self-insert but shadowed
-    by a multi-character key sequence to not be inserted.
-
-p.  Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
-    dereferenced if NULL (matching the documentation).
-
-q.  Extensive changes to readline to add enough state so that commands
-    requiring additional characters (searches, multi-key sequences, numeric
-    arguments, commands requiring an additional specifier character like
-    vi-mode change-char, etc.) work without synchronously waiting for
-    additional input.
-
-r.  Lots of changes so readline builds and runs on MinGW.
-
-s.  Readline no longer tries to modify the terminal settings when running in
-    callback mode.
-
-t.  The Readline display code no longer sets the location of the last invisible
-    character in the prompt if the \[\] sequence is empty.
-
-u.  The `change-case' command now correctly changes the case of multibyte
-    characters.
-
-v.  Changes to the shared library construction scripts to deal with Windows
-    DLL naming conventions for Cygwin.
-
-w.  Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
-    SIGWINCH.
-
-x.  Fixed the non-incremental search code in vi mode to dispose of any current
-    undo list when copying a line from the history into the current editing
-    buffer.
-
-y.  Fixed a bug that caused reversing the incremental search direction to
-    not work correctly.  
-    
-z.  Fixed the vi-mode `U' command to only undo up to the first time insert mode
-    was entered, as Posix specifies.
-
-aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
-    place.
-
-bb. Fixed a redisplay bug caused by moving the cursor vertically to a line
-    with invisible characters in the prompt in a multibyte locale.
-
-cc. Fixed a bug that could cause the terminal special chars to be bound in the
-    wrong keymap in vi mode.
-
-2.  New Features in Readline
-
-a.  The key sequence sent by the keypad `delete' key is now automatically   
-    bound to delete-char.
-
-b.  A negative argument to menu-complete now cycles backward through the
-    completion list.
-
-c.  A new bindable readline variable:  bind-tty-special-chars.  If non-zero,
-    readline will bind the terminal special characters to their readline
-    equivalents when it's called (on by default).
-
-d.  New bindable command: vi-rubout.  Saves deleted text for possible  
-    reinsertion, as with any vi-mode `text modification' command; `X' is bound
-    to this in vi command mode.
-
-e.  If the rl_completion_query_items is set to a value < 0, readline never
-    asks the user whether or not to view the possible completions.
-
-f.  The `C-w' binding in incremental search now understands multibyte
-    characters.
-
-g.  New application-callable auxiliary function, rl_variable_value, returns 
-    a string corresponding to a readline variable's value.
-
-h.  When parsing inputrc files and variable binding commands, the parser
-    strips trailing whitespace from values assigned to boolean variables
-    before checking them.
-
-i.  A new external application-controllable variable that allows the LINES   
-    and COLUMNS environment variables to set the window size regardless of
-    what the kernel returns.
-
--------------------------------------------------------------------------------
-This document details the changes between this version, readline-5.0,
-and the previous version, readline-4.3.
-
-1.  Changes to Readline
-
-a.  Fixes to avoid core dumps because of null pointer references in the
-    multibyte character code.
-
-b.  Fix to avoid infinite recursion caused by certain key combinations.
-
-c.  Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
-
-d.  Readline no longer tries to read ahead more than one line of input, even
-    when more is available.
-
-e.  Fixed the code that adjusts the point to not mishandle null wide
-    characters.
-
-f.  Fixed a bug in the history expansion `g' modifier that caused it to skip
-    every other match.
-
-g.  Fixed a bug that caused the prompt to overwrite previous output when the
-    output doesn't contain a newline and the locale supports multibyte
-    characters.  This same change fixes the problem of readline redisplay
-    slowing down dramatically as the line gets longer in multibyte locales.
-
-h.  History traversal with arrow keys in vi insertion mode causes the cursor
-    to be placed at the end of the new line, like in emacs mode.
-
-i.  The locale initialization code does a better job of using the right
-    precedence and defaulting when checking the appropriate environment
-    variables.
-
-j.  Fixed the history word tokenizer to handle <( and >( better when used as
-    part of bash.
-
-k.  The overwrite mode code received several bug fixes to improve undo.
-
-l.  Many speedups to the multibyte character redisplay code.
-
-m.  The callback character reading interface should not hang waiting to read
-    keyboard input.
-
-n.  Fixed a bug with redoing vi-mode `s' command.
-
-o.  The code that initializes the terminal tracks changes made to the terminal
-    special characters with stty(1) (or equivalent), so that these changes
-    are reflected in the readline bindings.  New application-callable function
-    to make it work:  rl_tty_unset_default_bindings().
-
-p.  Fixed a bug that could cause garbage to be inserted in the buffer when
-    changing character case in vi mode when using a multibyte locale.
-
-q.  Fixed a bug in the redisplay code that caused problems on systems
-    supporting multibyte characters when moving between history lines when the
-    new line has more glyphs but fewer bytes.
-
-r.  Undo and redo now work better after exiting vi insertion mode.
-
-s.  Make sure system calls are restarted after a SIGWINCH is received using
-    SA_RESTART.
-
-t.  Improvements to the code that displays possible completions when using
-    multibyte characters.
-
-u.  Fixed a problem when parsing nested if statements in inputrc files.
-
-v.  The completer now takes multibyte characters into account when looking for
-    quoted substrings on which to perform completion.
-
-w.  The history search functions now perform better bounds checking on the
-    history list.
-
-x.  Change to history expansion functions to treat `^' as equivalent to word 
-    one, as the documention states.
-
-y.  Some changes to the display code to improve display and redisplay of
-    multibyte characters.
-
-z.  Changes to speed up the multibyte character redisplay code.
-
-aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the
-    last character of a word if invoked while point was on the word's
-    next-to-last character.
-
-bb. Fixed a bug that could cause incorrect filename quoting when
-    case-insensitive completion was enabled and the word being completed
-    contained backslashes quoting word break characters.
-
-cc. Fixed a bug in redisplay triggered when the prompt string contains
-    invisible characters.
-
-dd. Fixed some display (and other) bugs encountered in multibyte locales
-    when a non-ascii character was the last character on a line.
-
-ee. Fixed some display bugs caused by multibyte characters in prompt strings.
-
-ff. Fixed a problem with history expansion caused by non-whitespace characters
-    used as history word delimiters.
-
-gg. Fixed a problem that could cause readline to refer to freed memory when
-    moving between history lines while doing searches.
-
-hh. Improvements to the code that expands and displays prompt strings
-    containing multibyte characters.
-
-ii. Fixed a problem with vi-mode not correctly remembering the numeric argument
-    to the last `c'hange command for later use with `.'.
-
-jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work   
-    incorrectly.
-
-kk. Fixed a problem in vi-mode that caused the last text modification command
-    to not be remembered across different command lines.
-
-ll. Fixed problems with changing characters and changing case at the end of
-    the line.
-
-mm. Fixed a problem with readline saving the contents of the current line
-    before beginning a non-interactive search.
-
-nn. Fixed a problem with EOF detection when using rl_event_hook.
-
-oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
-    arguments.
-
-2.  New Features in Readline
-
-a.  History expansion has a new `a' modifier equivalent to the `g' modifier
-    for compatibility with the BSD csh.
-
-b.  History expansion has a new `G' modifier equivalent to the BSD csh `g'
-    modifier, which performs a substitution once per word.
-
-c.  All non-incremental search operations may now undo the operation of
-    replacing the current line with the history line.
-
-d.  The text inserted by an `a' command in vi mode can be reinserted with
-    `.'.
-
-e.  New bindable variable, `show-all-if-unmodified'.  If set, the readline
-    completer will list possible completions immediately if there is more
-    than one completion and partial completion cannot be performed.
-
-f.  There is a new application-callable `free_history_entry()' function.
-
-g.  History list entries now contain timestamp information; the history file
-    functions know how to read and write timestamp information associated
-    with each entry.
-
-h.  Four new key binding functions have been added:
-
-	rl_bind_key_if_unbound()
-	rl_bind_key_if_unbound_in_map()
-	rl_bind_keyseq_if_unbound()
-	rl_bind_keyseq_if_unbound_in_map()
-
-i.  New application variable, rl_completion_quote_character, set to any
-    quote character readline finds before it calls the application completion
-    function.
-
-j.  New application variable, rl_completion_suppress_quote, settable by an   
-    application completion function.  If set to non-zero, readline does not
-    attempt to append a closing quote to a completed word.
-    
-k.  New application variable, rl_completion_found_quote, set to a non-zero
-    value if readline determines that the word to be completed is quoted.
-    Set before readline calls any application completion function.
-
-l.  New function hook, rl_completion_word_break_hook, called when readline
-    needs to break a line into words when completion is attempted.  Allows
-    the word break characters to vary based on position in the line.
-
-m.  New bindable command: unix-filename-rubout.  Does the same thing as
-    unix-word-rubout, but adds `/' to the set of word delimiters.
-
-n.  When listing completions, directories have a `/' appended if the
-    `mark-directories' option has been enabled.
-
--------------------------------------------------------------------------------
-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.
-
--------------------------------------------------------------------------------
-This document details the changes between this version, readline-4.2,
-and the previous version, readline-4.1.
-
-1.  Changes to Readline
-
-a.  When setting the terminal attributes on systems using `struct termio',
-    readline waits for output to drain before changing the attributes.
-
-b.  A fix was made to the history word tokenization code to avoid attempts to
-    dereference a null pointer.
-
-c.  Readline now defaults rl_terminal_name to $TERM if the calling application
-    has left it unset, and tries to initialize with the resultant value.
-
-d.  Instead of calling (*rl_getc_function)() directly to get input in certain
-    places, readline now calls rl_read_key() consistently.
-
-e.  Fixed a bug in the completion code that allowed a backslash to quote a
-    single quote inside a single-quoted string.
-
-f.  rl_prompt is no longer assigned directly from the argument to readline(),
-    but uses memory allocated by readline.  This allows constant strings to
-    be passed to readline without problems arising when the prompt processing
-    code wants to modify the string.
-
-g.  Fixed a bug that caused non-interactive history searches to return the
-    wrong line when performing multiple searches backward for the same string.
-
-h.  Many variables, function arguments, and function return values are now
-    declared `const' where appropriate, to improve behavior when linking with
-    C++ code.
-
-i.  The control character detection code now works better on systems where
-    `char' is unsigned by default.
-
-j.  The vi-mode numeric argument is now capped at 999999, just like emacs mode.
-
-k.  The Function, CPFunction, CPPFunction, and VFunction typedefs have been
-    replaced with a set of specific prototyped typedefs, though they are
-    still in the readline header files for backwards compatibility.
-
-m.  Nearly all of the (undocumented) internal global variables in the library
-    now have an _rl_ prefix -- there were a number that did not, like
-    screenheight, screenwidth, alphabetic, etc.
-
-n.  The ding() convenience function has been renamed to rl_ding(), though the
-    old function is still defined for backwards compatibility.
-
-o.  The completion convenience functions filename_completion_function,
-    username_completion_function, and completion_matches now have an rl_
-    prefix, though the old names are still defined for backwards compatibility.
-
-p.  The functions shared by readline and bash (linkage is satisfied from bash
-    when compiling with bash, and internally otherwise) now have an sh_ prefix.
-
-q.  Changed the shared library creation procedure on Linux and BSD/OS 4.x so
-    that the `soname' contains only the major version number rather than the
-    major and minor numbers.
-
-r.  Fixed a redisplay bug that occurred when the prompt spanned more than one
-    physical line and contained invisible characters.
-
-s.  Added a missing `includedir' variable to the Makefile.
-
-t.  When installing the shared libraries, make sure symbolic links are relative.
-
-u.  Added configure test so that it can set `${MAKE}' appropriately.
-
-v.  Fixed a bug in rl_forward that could cause the point to be set to before
-    the beginning of the line in vi mode.
-
-w.  Fixed a bug in the callback read-char interface to make it work when a
-    readline function pushes some input onto the input stream with
-    rl_execute_next (like the incremental search functions).
-
-x.  Fixed a file descriptor leak in the history file manipulation code that
-    was tripped when attempting to truncate a non-regular file (like
-    /dev/null).
-
-y.  Changes to make all of the exported readline functions declared in
-    readline.h have an rl_ prefix (rltty_set_default_bindings is now
-    rl_tty_set_default_bindings, crlf is now rl_crlf, etc.)
-
-z.  The formatted documentation included in the base readline distribution
-    is no longer removed on a `make distclean'.
-
-aa. Some changes were made to avoid gcc warnings with -Wall.
-
-bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so
-    `set keymap EMACS' works.
-
-cc. The history file writing and truncation functions now return a useful
-    status on error.
-
-dd. Fixed a bug that could cause applications to dereference a NULL pointer
-    if a NULL second argument was passed to history_expand().
-
-ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
-    value, rl_read_key() now immediately returns '\n' (which is assumed to   
-    be bound to accept-line).
-
-2.  New Features in Readline
-
-a.  The blink timeout for paren matching is now settable by applications,
-    via the rl_set_paren_blink_timeout() function.
-
-b.  _rl_executing_macro has been renamed to rl_executing_macro, which means
-    it's now part of the public interface.
-
-c.  Readline has a new variable, rl_readline_state, which is a bitmap that
-    encapsulates the current state of the library; intended for use by
-    callbacks and hook functions.
-
-d.  rlfe has a new -l option to log input and output (-a appends to logfile),
-    a new -n option to set the readline application name, and -v and -h
-    options for version and help information.
-
-e.  rlfe can now perform filename completion for the inferior process if the
-    OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the
-    inferior's current working directory.
-
-f.  A new file, rltypedefs.h, contains the new typedefs for function pointers
-    and is installed by `make install'.
-
-g.  New application-callable function rl_set_prompt(const char *prompt):
-    expands its prompt string argument and sets rl_prompt to the result.
-
-h.  New application-callable function rl_set_screen_size(int rows, int cols):
-    public method for applications to set readline's idea of the screen
-    dimensions.
-
-i.  The history example program (examples/histexamp.c) is now built as one
-    of the examples.
-
-j.  The documentation has been updated to cover nearly all of the public
-    functions and variables declared in readline.h.
-
-k.  New function, rl_get_screen_size (int *rows, int *columns), returns
-    readline's idea of the screen dimensions.
-
-l.  The timeout in rl_gather_tyi (readline keyboard input polling function)
-    is now settable via a function (rl_set_keyboard_input_timeout()).
-
-m.  Renamed the max_input_history variable to history_max_entries; the old
-    variable is maintained for backwards compatibility.
-
-n.  The list of characters that separate words for the history tokenizer is
-    now settable with a variable:  history_word_delimiters.  The default
-    value is as before.
-
-o.  There is a new history.3 manual page documenting the history library.
-
--------------------------------------------------------------------------------
-This document details the changes between this version, readline-4.1,
-and the previous version, readline-4.0.
-
-1.  Changes to Readline
-
-a.  Changed the HTML documents so that the table-of-contents is no longer
-    a separate file.
-
-b.  Changes to the shared object configuration for: Irix 5.x, Irix 6.x,
-    OSF/1.
-
-c.  The shared library major and minor versions are now constructed
-    automatically by configure and substituted into the makefiles.
-
-d.  It's now possible to install the shared libraries separately from the
-    static libraries.
-
-e.  The history library tries to truncate the history file only if it is a
-    regular file.
-
-f.  A bug that caused _rl_dispatch to address negative array indices on
-    systems with signed chars was fixed.
-
-g.  rl-yank-nth-arg now leaves the history position the same as when it was
-    called.
-
-h.  Changes to the completion code to handle MS-DOS drive-letter:pathname
-    filenames.
-
-i.  Completion is now case-insensitive by default on MS-DOS.
-
-j.  Fixes to the history file manipulation code for MS-DOS.
-
-k.  Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS.
-
-l.  Some fixes were made to the redisplay code for better operation on MS-DOS.
-
-m.  The quoted-insert code will now insert tty special chars like ^C.
-
-n.  A bug was fixed that caused the display code to reference memory before
-    the start of the prompt string.
-
-o.  More support for __EMX__ (OS/2).
-
-p.  A bug was fixed in readline's signal handling that could cause infinite
-    recursion in signal handlers.
-
-q.  A bug was fixed that caused the point to be less than zero when rl_forward
-    was given a very large numeric argument.
-
-r.  The vi-mode code now gets characters via the application-settable value
-    of rl_getc_function rather than calling rl_getc directly.
-
-s.  The history file code now uses O_BINARY mode when reading and writing
-    the history file on cygwin32.
-
-t.  Fixed a bug in the redisplay code for lines with more than 256 line
-    breaks.
-
-u.  A bug was fixed which caused invisible character markers to not be
-    stripped from the prompt string if the terminal was in no-echo mode.
-    
-v.  Readline no longer tries to get the variables it needs for redisplay 
-    from the termcap entry if the calling application has specified its
-    own redisplay function.  Readline treats the terminal as `dumb' in
-    this case.
-
-w.  Fixes to the SIGWINCH code so that a multiple-line prompt with escape
-    sequences is redrawn correctly.
-
-x.  Changes to the install and install-shared targets so that the libraries
-    and header files are installed separately.
-
-2.  New Features in Readline
-
-a.  A new Readline `user manual' is in doc/rluserman.texinfo.
-
-b.  Parentheses matching is now always compiled into readline, and enabled
-    or disabled when the value of the `blink-matching-paren' variable is
-    changed.
-
-c.  MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
-
-d.  MS-DOS systems now use ~/_history as the default history file.
-
-e.  history-search-{forward,backward} now leave the point at the end of the
-    line when the string to search for is empty, like
-    {reverse,forward}-search-history.
-
-f.  history-search-{forward,backward} now leave the last history line found
-    in the readline buffer if the second or subsequent search fails.
-
-g.  New function for use by applications:  rl_on_new_line_with_prompt, used
-    when an application displays the prompt itself before calling readline().
-
-h.  New variable for use by applications:  rl_already_prompted.  An application
-    that displays the prompt itself before calling readline() must set this to
-    a non-zero value.
-
-i.  A new variable, rl_gnu_readline_p, always 1.  The intent is that an
-    application can verify whether or not it is linked with the `real'
-    readline library or some substitute.
-
-j.  Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program
-    is included in the examples subdirectory, though it is not built
-    by default.
-
--------------------------------------------------------------------------------
-This document details the changes between this version, readline-4.0,
-and the previous version, readline-2.2.
-
-1.  Changes to Readline
-
-a.  The version number is now 4.0, to match the major and minor version
-    numbers on the shared readline and history libraries.  Future
-    releases will maintain the identical numbering.
-
-b.  Fixed a typo in the `make install' recipe that copied libreadline.a
-    to libhistory.old right after installing it.
-
-c.  The readline and history info files are now installed out of the source
-    directory if they are not found in the build directory.
-
-d.  The library no longer exports a function named `savestring' -- backwards
-    compatibility be damned.
-
-e.  There is no longer any #ifdef SHELL code in the source files.
-
-f.  Some changes were made to the key binding code to fix memory leaks and
-    better support Win32 systems.
-
-g.  Fixed a silly typo in the paren matching code -- it's microseconds, not
-    milliseconds.
-
-h.  The readline library should be compilable by C++ compilers.
-
-i.  The readline.h public header file now includes function prototypes for
-    all readline functions, and some changes were made to fix errors in the
-    source files uncovered by the use of prototypes.
-
-j.  The maximum numeric argument is now clamped at 1000000.
-
-k.  Fixes to rl_yank_last_arg to make it behave better.
-
-l.  Fixed a bug in the display code that caused core dumps if the prompt
-    string length exceeded 1024 characters.
-
-m.  The menu completion code was fixed to properly insert a single completion
-    if there is only one match.
-
-n.  A bug was fixed that caused the display code to improperly display tabs
-    after newlines.
-
-o.  A fix was made to the completion code in which a typo caused the wrong
-    value to be passed to the function that computed the longest common
-    prefix of the list of matches.
-
-p.  The completion code now checks the value of rl_filename_completion_desired,
-    which is set by application-supplied completion functions to indicate
-    that filename completion is being performed, to decide whether or not to
-    call an application-supplied `ignore completions' function.
-
-q.  Code was added to the history library to catch history substitutions
-    using `&' without a previous history substitution or search having been
-    performed.
-
-
-2.  New Features in Readline
-
-a.  There is a new script, support/shobj-conf, to do system-specific shared
-    object and library configuration.  It generates variables for configure
-    to substitute into makefiles.  The README file provides a detailed
-    explanation of the shared library creation process.
-
-b.  Shared libraries and objects are now built in the `shlib' subdirectory.
-    There is a shlib/Makefile.in to control the build process.  `make shared'
-    from the top-level directory is still the right way to build shared
-    versions of the libraries.
-
-c.  rlconf.h is now installed, so applications can find out which features
-    have been compiled into the installed readline and history libraries.
-
-d.  rlstdc.h is now an installed header file.
-
-e.  Many changes to the signal handling:
-        o Readline now catches SIGQUIT and cleans up the tty before returning;
-        o A new variable, rl_catch_signals, is available to application writers 
-          to indicate to readline whether or not it should install its own
-          signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
-          SIGTTIN, and SIGTTOU;
-        o A new variable, rl_catch_sigwinch, is available to application
-          writers to indicate to readline whether or not it should install its
-          own signal handler for SIGWINCH, which will chain to the calling
-          applications's SIGWINCH handler, if one is installed;
-        o There is a new function, rl_free_line_state, for application signal
-          handlers to call to free up the state associated with the current
-          line after receiving a signal;
-        o There is a new function, rl_cleanup_after_signal, to clean up the
-          display and terminal state after receiving a signal;
-        o There is a new function, rl_reset_after_signal, to reinitialize the
-          terminal and display state after an application signal handler
-          returns and readline continues
-
-f.  There is a new function, rl_resize_terminal, to reset readline's idea of
-    the screen size after a SIGWINCH.
-
-g.  New public functions: rl_save_prompt and rl_restore_prompt.  These were
-    previously private functions with a `_' prefix.  These functions are
-    used when an application wants to write a message to the `message area'
-    with rl_message and have the prompt restored correctly when the message
-    is erased.
-
-h.  New function hook: rl_pre_input_hook, called just before readline starts
-    reading input, after initialization.
-
-i.  New function hook: rl_display_matches_hook, called when readline would
-    display the list of completion matches.  The new function
-    rl_display_match_list is what readline uses internally, and is available
-    for use by application functions called via this hook.
-
-j.  New bindable function, delete-char-or-list, like tcsh.
-
-k.  A new variable, rl_erase_empty_line, which, if set by an application using
-    readline, will cause readline to erase, prompt and all, lines on which the
-    only thing typed was a newline.
-
-l.  There is a new script, support/shlib-install, to install and uninstall
-    the shared readline and history libraries.
-
-m.  A new bindable variable, `isearch-terminators', which is a string
-    containing the set of characters that should terminate an incremental
-    search without being executed as a command.
-
-n.  A new bindable function, forward-backward-delete-char.
-
--------------------------------------------------------------------------------
-This document details the changes between this version, readline-2.2,
-and the previous version, readline-2.1.
-
-1.  Changes to Readline
-
-a.  Added a missing `extern' to a declaration in readline.h that kept
-    readline from compiling cleanly on some systems.
-
-b.  The history file is now opened with mode 0600 when it is written for
-    better security.
-
-c.  Changes were made to the SIGWINCH handling code so that prompt redisplay
-    is done better.
-
-d.  ^G now interrupts incremental searches correctly.
-
-e.  A bug that caused a core dump when the set of characters to be quoted
-    when completing words was empty was fixed.
-
-f.  Fixed a problem in the readline test program rltest.c that caused a core
-    dump.
-
-g.  The code that handles parser directives in inputrc files now displays
-    more error messages.
-
-h.  The history expansion code was fixed so that the appearance of the
-    history comment character at the beginning of a word inhibits history
-    expansion for that word and the rest of the input line.
-
-i.  The code that prints completion listings now behaves better if one or
-    more of the filenames contains non-printable characters.
-
-j.  The time delay when showing matching parentheses is now 0.5 seconds.
-
-
-2.  New Features in Readline
-
-a.  There is now an option for `iterative' yank-last-arg handline, so a user
-    can keep entering `M-.', yanking the last argument of successive history
-    lines.
-
-b.  New variable, `print-completions-horizontally', which causes completion
-    matches to be displayed across the screen (like `ls -x') rather than up
-    and down the screen (like `ls').
-
-c.  New variable, `completion-ignore-case', which causes filename completion
-    and matching to be performed case-insensitively.
-
-d.  There is a new bindable command, `magic-space', which causes history
-    expansion to be performed on the current readline buffer and a space to
-    be inserted into the result.
-
-e.  There is a new bindable command, `menu-complete', which enables tcsh-like
-    menu completion (successive executions of menu-complete insert a single
-    completion match, cycling through the list of possible completions).
-
-f.  There is a new bindable command, `paste-from-clipboard', for use on Win32
-    systems, to insert the text from the Win32 clipboard into the editing
-    buffer.
-
-g.  The key sequence translation code now understands printf-style backslash
-    escape sequences, including \NNN octal escapes.  These escape sequences
-    may be used in key sequence definitions or macro values.
-
-h.  An `$include' inputrc file parser directive has been added.

-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-Basic Installation
-==================
-
-These are installation instructions for Readline-5.2.
-
-The simplest way to compile readline is:
-
-  1. `cd' to the directory containing the readline source code and type
-     `./configure' to configure readline for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes some time.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile readline and build the static readline
-     and history libraries.  If supported, the shared readline and history
-     libraries will be built also.  See below for instructions on compiling
-     the other parts of the distribution.  Typing `make everything' will
-     cause the static and shared libraries (if supported) and the example
-     programs to be built.
-
-  3. Type `make install' to install the static readline and history
-     libraries, the readline include files, the documentation, and, if
-     supported, the shared readline and history libraries.
-
-  4. You can remove the created libraries and object files from the
-     build directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile readline for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the readline developers, and should be used with care.
-
-The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It
-uses those values to create a `Makefile' in the build directory,
-and Makefiles in the `doc', `shlib', and `examples'
-subdirectories.  It also creates a `config.h' file containing
-system-dependent definitions.  Finally, it creates a shell script
-`config.status' that you can run in the future to recreate the
-current configuration, a file `config.cache' that saves the
-results of its tests to speed up reconfiguring, and a file
-`config.log' containing compiler output (useful mainly for
-debugging `configure'). 
-
-If you need to do unusual things to compile readline, please try
-to figure out how `configure' could check whether to do them, and
-mail diffs or instructions to <bug-readline@gnu.org> so they can
-be considered for the next release.  If at some point
-`config.cache' contains results you don't want to keep, you may
-remove or edit it. 
-
-The file `configure.in' is used to create `configure' by a
-program called `autoconf'.  You only need `configure.in' if you
-want to change it or regenerate `configure' using a newer version
-of `autoconf'.  The readline `configure.in' requires autoconf
-version 2.50 or newer. 
-
-Compilers and Options
-=====================
-
-Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
-
-     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
-
-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
-You can compile readline for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile readline for one architecture at a
-time in the source code directory.  After you have installed
-readline for one architecture, use `make distclean' before
-reconfiguring for another architecture. 
-
-Installation Names
-==================
-
-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
-architecture-specific files and architecture-independent files. 
-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 need to determine by the type of host readline
-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 (e.g., i386-unknown-freebsd4.2). 
-
-See the file `config.sub' for the possible values of each field.
-
-Sharing Defaults
-================
-
-If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: the readline `configure' looks for a site script, but not
-all `configure' scripts do.
-
-Operation Controls
-==================
-
-`configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
-`--help'
-     Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--version'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`configure' also accepts some other, not widely useful, options.
-
-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_LIBPREF	The prefix to use when generating the filename of the shared
-		library.  The default is `lib'; Cygwin uses `cyg'.
-
-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_DLLVERSION The version number for shared libraries that determines API
-		compatibility between readline versions and the underlying
-		system.  Used only on Cygwin.  Defaults to $SHLIB_MAJOR, but
-		can be overridden at configuration time by defining DLLVERSION
-		in the environment.
-
-SHLIB_DOT	The character used to separate the name of the shared library
-		from the suffix and version information.  The default is `.';
-		systems like Cygwin which don't separate version information
-		from the library name should set this to the empty string.
-
-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'.

-This is a terse description of the new features added to readline-5.2 since
-the release of readline-5.1.
-
-1.  New Features in Readline
-
-a.  Calling applications can now set the keyboard timeout to 0, allowing
-    poll-like behavior.
-
-b.  The value of SYS_INPUTRC (configurable at compilation time) is now used as
-    the default last-ditch startup file.
-
-c.  The history file reading functions now allow windows-like \r\n line
-    terminators.

-Introduction
-============
-
-This is the Gnu Readline library, version 5.2.
-
-The Readline library provides a set of functions for use by applications
-that allow users to edit command lines as they are typed in.  Both
-Emacs and vi editing modes are available.  The Readline library includes
-additional functions to maintain a list of previously-entered command
-lines, to recall and perhaps reedit those lines, and perform csh-like
-history expansion on previous commands.
-
-The history facilites are also placed into a separate library, the
-History library, as part of the build process.  The History library
-may be used without Readline in applications which desire its
-capabilities.
-
-The Readline library is free software, distributed under the terms of
-the [GNU] General Public License, version 2.  For more information, see
-the file COPYING.
-
-To build the library, try typing `./configure', then `make'.  The
-configuration process is automated, so no further intervention should
-be necessary.  Readline builds with `gcc' by default if it is
-available.  If you want to use `cc' instead, type
-
-        CC=cc ./configure
-
-if you are using a Bourne-style shell.  If you are not, the following
-may work:
-
-        env CC=cc ./configure
-
-Read the file INSTALL in this directory for more information about how
-to customize and control the build process.
-
-The file rlconf.h contains C preprocessor defines that enable and disable
-certain Readline features.
-
-The special make target `everything' will build the static and shared
-libraries (if the target platform supports them) and the examples.
-
-Examples
-========
-
-There are several example programs that use Readline features in the
-examples directory.  The `rl' program is of particular interest.  It
-is a command-line interface to Readline, suitable for use in shell
-scripts in place of `read'.
-
-Shared Libraries
-================
-
-There is skeletal 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_LIBPREF	The prefix to use when generating the filename of the shared
-		library.  The default is `lib'; Cygwin uses `cyg'.
-
-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_DLLVERSION The version number for shared libraries that determines API
-		compatibility between readline versions and the underlying
-		system.  Used only on Cygwin.  Defaults to $SHLIB_MAJOR, but
-		can be overridden at configuration time by defining DLLVERSION
-		in the environment.
-
-SHLIB_DOT	The character used to separate the name of the shared library
-		from the suffix and version information.  The default is `.';
-		systems like Cygwin which don't separate version information
-		from the library name should set this to the empty string.
-
-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.
-
-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'.  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'. 
-
-Documentation
-=============
-
-The documentation for the Readline and History libraries appears in
-the `doc' subdirectory.  There are three texinfo files and a
-Unix-style manual page describing the facilities available in the
-Readline library.  The texinfo files include both user and
-programmer's manuals.  HTML versions of the manuals appear in the
-`doc' subdirectory as well. 
-
-Reporting Bugs
-==============
-
-Bug reports for Readline should be sent to:
-
-        bug-readline@gnu.org
-
-When reporting a bug, please include the following information:
-
-        * the version number and release status of Readline (e.g., 4.2-release)
-        * the machine and OS that it is running on
-        * a list of the compilation flags or the contents of `config.h', if
-          appropriate
-        * a description of the bug
-        * a recipe for recreating the bug reliably
-        * a fix for the bug if you have one!
-
-If you would like to contact the Readline maintainer directly, send mail
-to bash-maintainers@gnu.org.
-
-Since Readline is developed along with bash, the bug-bash@gnu.org mailing
-list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
-Readline bug reports and fixes.

-Reply-to: rms@gnu.org

-I think Allbery's suggestion is a good one.  So please add this text
-in a suitable place.  Please don't put it in the GPL itself; that
-should be the same as the GPL everywhere else.  Putting it in the
-README and/or the documentation would be a good idea.
-
-
-======================================================================
-Our position on the use of Readline through a shared-library linking
-mechanism is that there is no legal difference between shared-library
-linking and static linking--either kind of linking combines various
-modules into a single larger work.  The conditions for using Readline
-in a larger work are stated in section 3 of the GNU GPL.

-dnl Macro to add for using GNU gettext.
-
-dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
-dnl    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl    implementations (in libc or libintl) without the ngettext() function
-dnl    will be ignored.  If NEEDSYMBOL is specified and is
-dnl    'need-formatstring-macros', then GNU gettext implementations that don't
-dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(top_builddir)/intl/' is used.
-dnl
-dnl The result of the configuration is one of three cases:
-dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
-dnl    and used.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 2) GNU gettext has been found in the system's C library.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 3) No internationalization, always use English msgid.
-dnl    Catalog format: none
-dnl    Catalog extension: none
-dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
-dnl The use of .gmo is historical (it was needed to avoid overwriting the
-dnl GNU format catalogs when building on a platform with an X/Open gettext),
-dnl but we keep it in order not to force irrelevant filename changes on the
-dnl maintainers.

-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
