-.SH COPYRIGHT
-.if t The GNU History Library is Copyright \(co 1989-2001 by the Free Software Foundation, Inc.
-.if n The GNU History Library is Copyright (C) 1989-2001 by the Free Software Foundation, Inc.
-.SH DESCRIPTION
-Many programs read input from the user a line at a time.  The GNU
-History library is able to keep track of those lines, associate arbitrary
-data with each line, and utilize information from previous lines in
-composing new ones. 
-.PP
-.SH "HISTORY EXPANSION"
-.PP
-The history library supports a history expansion feature that
-is identical to the history expansion in
-.BR bash.
-This section describes what syntax features are available.
-.PP
-History expansions introduce words from the history list into
-the input stream, making it easy to repeat commands, insert the
-arguments to a previous command into the current input line, or
-fix errors in previous commands quickly.
-.PP
-History expansion is usually performed immediately after a complete line
-is read.
-It takes place in two parts.
-The first is to determine which line from the history list
-to use during substitution.
-The second is to select portions of that line for inclusion into
-the current one.
-The line selected from the history is the \fIevent\fP,
-and the portions of that line that are acted upon are \fIwords\fP.
-Various \fImodifiers\fP are available to manipulate the selected words.
-The line is broken into words in the same fashion as \fBbash\fP
-does when reading input,
-so that several words that would otherwise be separated 
-are considered one word when surrounded by quotes (see the
-description of \fBhistory_tokenize()\fP below).
-History expansions are introduced by the appearance of the
-history expansion character, which is \^\fB!\fP\^ by default.
-Only backslash (\^\fB\e\fP\^) and single quotes can quote
-the history expansion character.
-.SS Event Designators
-.PP
-An event designator is a reference to a command line entry in the
-history list.
-.PP
-.PD 0
-.TP
-.B !
-Start a history substitution, except when followed by a
-.BR blank ,
-newline, = or (.
-.TP
-.B !\fIn\fR
-Refer to command line
-.IR n .
-.TP
-.B !\-\fIn\fR
-Refer to the current command line minus
-.IR n .
-.TP
-.B !!
-Refer to the previous command.  This is a synonym for `!\-1'.
-.TP
-.B !\fIstring\fR
-Refer to the most recent command starting with 
-.IR string .
-.TP
-.B !?\fIstring\fR\fB[?]\fR
-Refer to the most recent command containing
-.IR string .
-The trailing \fB?\fP may be omitted if
-.I string
-is followed immediately by a newline.
-.TP
-.B \d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u
-Quick substitution.  Repeat the last command, replacing
-.I string1
-with
-.IR string2 .
-Equivalent to
-``!!:s/\fIstring1\fP/\fIstring2\fP/''
-(see \fBModifiers\fP below).
-.TP
-.B !#
-The entire command line typed so far.
-.PD
-.SS Word Designators
-.PP
-Word designators are used to select desired words from the event.
-A 
-.B :
-separates the event specification from the word designator.
-It may be omitted if the word designator begins with a
-.BR ^ ,
-.BR $ ,
-.BR * ,
-.BR \- ,
-or
-.BR % .
-Words are numbered from the beginning of the line,
-with the first word being denoted by 0 (zero).
-Words are inserted into the current line separated by single spaces.
-.PP
-.PD 0
-.TP
-.B 0 (zero)
-The zeroth word.  For the shell, this is the command
-word.
-.TP
-.I n
-The \fIn\fRth word.
-.TP
-.B ^
-The first argument.  That is, word 1.
-.TP
-.B $
-The last argument.
-.TP
-.B %
-The word matched by the most recent `?\fIstring\fR?' search.
-.TP
-.I x\fB\-\fPy
-A range of words; `\-\fIy\fR' abbreviates `0\-\fIy\fR'.
-.TP
-.B *
-All of the words but the zeroth.  This is a synonym
-for `\fI1\-$\fP'.  It is not an error to use
-.B *
-if there is just one
-word in the event; the empty string is returned in that case.
-.TP
-.B x*
-Abbreviates \fIx\-$\fP.
-.TP
-.B x\-
-Abbreviates \fIx\-$\fP like \fBx*\fP, but omits the last word.
-.PD
-.PP
-If a word designator is supplied without an event specification, the
-previous command is used as the event.
-.SS Modifiers
-.PP
-After the optional word designator, there may appear a sequence of
-one or more of the following modifiers, each preceded by a `:'.
-.PP
-.PD 0
-.PP
-.TP
-.B h
-Remove a trailing file name component, leaving only the head.
-.TP
-.B t
-Remove all leading file name components, leaving the tail.
-.TP
-.B r
-Remove a trailing suffix of the form \fI.xxx\fP, leaving the
-basename.
-.TP
-.B e
-Remove all but the trailing suffix.
-.TP
-.B p
-Print the new command but do not execute it.
-.TP
-.B q
-Quote the substituted words, escaping further substitutions.
-.TP
-.B x
-Quote the substituted words as with
-.BR q ,
-but break into words at
-.B blanks
-and newlines.
-.TP
-.B s/\fIold\fP/\fInew\fP/
-Substitute
-.I new
-for the first occurrence of
-.I old
-in the event line.  Any delimiter can be used in place of /.  The
-final delimiter is optional if it is the last character of the
-event line.  The delimiter may be quoted in
-.I old
-and
-.I new
-with a single backslash.  If & appears in
-.IR new ,
-it is replaced by
-.IR old .
-A single backslash will quote the &.  If
-.I old
-is null, it is set to the last
-.I old
-substituted, or, if no previous history substitutions took place,
-the last
-.I string
-in a
-.B !?\fIstring\fR\fB[?]\fR
-search.
-.TP
-.B &
-Repeat the previous substitution.
-.TP
-.B g
-Cause changes to be applied over the entire event line.  This is
-used in conjunction with `\fB:s\fP' (e.g., `\fB:gs/\fIold\fP/\fInew\fP/\fR')
-or `\fB:&\fP'.  If used with
-`\fB:s\fP', any delimiter can be used
-in place of /, and the final delimiter is optional
-if it is the last character of the event line.
-.PD
-.SH "PROGRAMMING WITH HISTORY FUNCTIONS"
-This section describes how to use the History library in other programs.
-.SS Introduction to History
-.PP
-The programmer using the History library has available functions
-for remembering lines on a history list, associating arbitrary data
-with a line, removing lines from the list, searching through the list
-for a line containing an arbitrary text string, and referencing any line
-in the list directly.  In addition, a history \fIexpansion\fP function
-is available which provides for a consistent user interface across
-different programs.
-.PP
-The user using programs written with the History library has the
-benefit of a consistent user interface with a set of well-known
-commands for manipulating the text of previous lines and using that text
-in new commands.  The basic history manipulation commands are
-identical to
-the history substitution provided by \fBbash\fP.
-.PP
-If the programmer desires, he can use the Readline library, which
-includes some history manipulation by default, and has the added
-advantage of command line editing.
-.PP
-Before declaring any functions using any functionality the History
-library provides in other code, an application writer should include
-the file
-.FN <readline/history.h>
-in any file that uses the
-History library's features.  It supplies extern declarations for all
-of the library's public functions and variables, and declares all of
-the public data structures.
-
-.SS History Storage
-.PP
-The history list is an array of history entries.  A history entry is
-declared as follows:
-.PP
-.Vb "typedef void *" histdata_t;
-.PP
-.nf
-typedef struct _hist_entry {
-  char *line;
-  histdata_t data;
-} HIST_ENTRY;
-.fi
-.PP
-The history list itself might therefore be declared as
-.PP
-.Vb "HIST_ENTRY **" the_history_list;
-.PP
-The state of the History library is encapsulated into a single structure:
-.PP
-.nf
-/*
- * A structure used to pass around the current state of the history.
- */
-typedef struct _hist_state {
-  HIST_ENTRY **entries; /* Pointer to the entries themselves. */
-  int offset;           /* The location pointer within this array. */
-  int length;           /* Number of elements within this array. */
-  int size;             /* Number of slots allocated to this array. */
-  int flags;
-} HISTORY_STATE;
-.fi
-.PP
-If the flags member includes \fBHS_STIFLED\fP, the history has been
-stifled.
-.SH "History Functions"
-.PP
-This section describes the calling sequence for the various functions
-exported by the GNU History library.
-.SS Initializing History and State Management
-This section describes functions used to initialize and manage
-the state of the History library when you want to use the history
-functions in your program.
-
-.Fn1 void using_history void
-Begin a session in which the history functions might be used.  This
-initializes the interactive variables.
-
-.Fn1 "HISTORY_STATE *" history_get_history_state void
-Return a structure describing the current state of the input history.
-
-.Fn1 void history_set_history_state "HISTORY_STATE *state"
-Set the state of the history list according to \fIstate\fP.
-
-.SS History List Management
-
-These functions manage individual entries on the history list, or set
-parameters managing the list itself.
-
-.Fn1 void add_history "const char *string"

-field (if any) is set to \fBNULL\fP.
-
-.Fn1 "HIST_ENTRY *" remove_history "int which"
-Remove history entry at offset \fIwhich\fP from the history.  The
-removed element is returned so you can free the line, data,
-and containing structure.
-
-.Fn3 "HIST_ENTRY *" replace_history_entry "int which" "const char *line" "histdata_t data"
-Make the history entry at offset \fIwhich\fP have \fIline\fP and \fIdata\fP.

-of an invalid \fIwhich\fP, a \fBNULL\fP pointer is returned.
-
-.Fn1 void clear_history "void"
-Clear the history list by deleting all the entries.
-
-.Fn1 void stifle_history "int max"
-Stifle the history list, remembering only the last \fImax\fP entries.
-
-.Fn1 int unstifle_history "void"
-Stop stifling the history.  This returns the previous amount the
-history was stifled.  The value is positive if the history was
-stifled, negative if it wasn't.
-
-.Fn1 int history_is_stifled "void"
-Returns non-zero if the history is stifled, zero if it is not.
-
-.SS Information About the History List
-
-These functions return information about the entire history list or
-individual list entries.
-
-.Fn1 "HIST_ENTRY **" history_list "void"
-Return a \fBNULL\fP terminated array of \fIHIST_ENTRY *\fP which is the
-current input history.  Element 0 of this list is the beginning of time.

-
-.Fn1 int where_history "void"
-Returns the offset of the current history element.
-
-.Fn1 "HIST_ENTRY *" current_history "void"

-\fBwhere_history()\fP.  If there is no entry there, return a \fBNULL\fP
-pointer.
-
-.Fn1 "HIST_ENTRY *" history_get "int offset"
-Return the history entry at position \fIoffset\fP, starting from
-\fBhistory_base\fP.
-If there is no entry there, or if \fIoffset\fP
-is greater than the history length, return a \fBNULL\fP pointer.
-
-.Fn1 int history_total_bytes "void"
-Return the number of bytes that the primary history entries are using.
-This function returns the sum of the lengths of all the lines in the
-history.
-
-.SS Moving Around the History List
-
-These functions allow the current index into the history list to be
-set or changed.
-
-.Fn1 int history_set_pos "int pos"
-Set the current history offset to \fIpos\fP, an absolute index
-into the list.
-Returns 1 on success, 0 if \fIpos\fP is less than zero or greater
-than the number of history entries.
-
-.Fn1 "HIST_ENTRY *" previous_history "void"
-Back up the current history offset to the previous history entry, and
-return a pointer to that entry.  If there is no previous entry, return
-a \fBNULL\fP pointer.
-
-.Fn1 "HIST_ENTRY *" next_history "void"
-Move the current history offset forward to the next history entry, and
-return the a pointer to that entry.  If there is no next entry, return
-a \fBNULL\fP pointer.
-
-.SS Searching the History List
-
-These functions allow searching of the history list for entries containing
-a specific string.  Searching may be performed both forward and backward
-from the current history position.  The search may be \fIanchored\fP,
-meaning that the string must match at the beginning of the history entry.
-
-.Fn2 int history_search "const char *string" "int direction"
-Search the history for \fIstring\fP, starting at the current history offset.
-If \fIdirection\fP is less than 0, then the search is through
-previous entries, otherwise through subsequent entries.
-If \fIstring\fP is found, then
-the current history index is set to that history entry, and the value
-returned is the offset in the line of the entry where
-\fIstring\fP was found.  Otherwise, nothing is changed, and a -1 is
-returned.
-
-.Fn2 int history_search_prefix "const char *string" "int direction"
-Search the history for \fIstring\fP, starting at the current history
-offset.  The search is anchored: matching lines must begin with
-\fIstring\fP.  If \fIdirection\fP is less than 0, then the search is
-through previous entries, otherwise through subsequent entries.
-If \fIstring\fP is found, then the
-current history index is set to that entry, and the return value is 0. 
-Otherwise, nothing is changed, and a -1 is returned. 
-
-.Fn3 int history_search_pos "const char *string" "int direction" "int pos"
-Search for \fIstring\fP in the history list, starting at \fIpos\fP, an
-absolute index into the list.  If \fIdirection\fP is negative, the search
-proceeds backward from \fIpos\fP, otherwise forward.  Returns the absolute
-index of the history element where \fIstring\fP was found, or -1 otherwise.
-
-.SS Managing the History File
-The History library can read the history from and write it to a file.
-This section documents the functions for managing a history file.
-
-.Fn1 int read_history "const char *filename"
-Add the contents of \fIfilename\fP to the history list, a line at a time.
-If \fIfilename\fP is \fBNULL\fP, then read from \fI~/.history\fP.
-Returns 0 if successful, or \fBerrno\fP if not.
-
-.Fn3 int read_history_range "const char *filename" "int from" "int to"
-Read a range of lines from \fIfilename\fP, adding them to the history list.
-Start reading at line \fIfrom\fP and end at \fIto\fP.
-If \fIfrom\fP is zero, start at the beginning.  If \fIto\fP is less than
-\fIfrom\fP, then read until the end of the file.  If \fIfilename\fP is
-\fBNULL\fP, then read from \fI~/.history\fP.  Returns 0 if successful,
-or \fBerrno\fP if not.
-
-.Fn1 int write_history "const char *filename"
-Write the current history to \fIfilename\fP, overwriting \fIfilename\fP
-if necessary.
-If \fIfilename\fP is \fBNULL\fP, then write the history list to \fI~/.history\fP.
-Returns 0 on success, or \fBerrno\fP on a read or write error.
-
-
-.Fn2 int append_history "int nelements" "const char *filename"
-Append the last \fInelements\fP of the history list to \fIfilename\fP.
-If \fIfilename\fP is \fBNULL\fP, then append to \fI~/.history\fP.
-Returns 0 on success, or \fBerrno\fP on a read or write error.
-
-.Fn2 int history_truncate_file "const char *filename" "int nlines"
-Truncate the history file \fIfilename\fP, leaving only the last
-\fInlines\fP lines.
-If \fIfilename\fP is \fBNULL\fP, then \fI~/.history\fP is truncated.
-Returns 0 on success, or \fBerrno\fP on failure.
-
-.SS History Expansion
-
-These functions implement history expansion.
-
-.Fn2 int history_expand "char *string" "char **output"
-Expand \fIstring\fP, placing the result into \fIoutput\fP, a pointer
-to a string.  Returns:
-.RS
-.PD 0
-.TP
-0
-If no expansions took place (or, if the only change in
-the text was the removal of escape characters preceding the history expansion
-character);
-.TP
-1
-if expansions did take place;
-.TP
--1
-if there was an error in expansion;
-.TP
-2
-if the returned line should be displayed, but not executed,
-as with the \fB:p\fP modifier.
-.PD
-.RE
-If an error ocurred in expansion, then \fIoutput\fP contains a descriptive
-error message.
-
-.Fn3 "char *" get_history_event "const char *string" "int *cindex" "int qchar"
-Returns the text of the history event beginning at \fIstring\fP +
-\fI*cindex\fP.  \fI*cindex\fP is modified to point to after the event
-specifier.  At function entry, \fIcindex\fP points to the index into
-\fIstring\fP where the history event specification begins.  \fIqchar\fP
-is a character that is allowed to end the event specification in addition
-to the ``normal'' terminating characters.
-
-.Fn1 "char **" history_tokenize "const char *string"
-Return an array of tokens parsed out of \fIstring\fP, much as the
-shell might.
-The tokens are split on the characters in the
-\fBhistory_word_delimiters\fP variable,
-and shell quoting conventions are obeyed.
-
-.Fn3 "char *" history_arg_extract "int first" "int last" "const char *string"
-Extract a string segment consisting of the \fIfirst\fP through \fIlast\fP
-arguments present in \fIstring\fP.  Arguments are split using
-\fBhistory_tokenize()\fP.
-
-.SS History Variables
-
-This section describes the externally-visible variables exported by
-the GNU History Library.
-
-.Vb int history_base
-The logical offset of the first entry in the history list.
-
-.Vb int history_length
-The number of entries currently stored in the history list.
-
-.Vb int history_max_entries
-The maximum number of history entries.  This must be changed using
-\fBstifle_history()\fP.
-
-.Vb char history_expansion_char
-The character that introduces a history event.  The default is \fB!\fP.
-Setting this to 0 inhibits history expansion.
-
-.Vb char history_subst_char
-The character that invokes word substitution if found at the start of
-a line.  The default is \fB^\fP.
-
-.Vb char history_comment_char
-During tokenization, if this character is seen as the first character
-of a word, then it and all subsequent characters up to a newline are
-ignored, suppressing history expansion for the remainder of the line.
-This is disabled by default.
-
-.Vb "char *" history_word_delimiters
-The characters that separate tokens for \fBhistory_tokenize()\fP.
-The default value is \fB"\ \et\en()<>;&|"\fP.
-
-.Vb "char *" history_no_expand_chars
-The list of characters which inhibit history expansion if found immediately
-following \fBhistory_expansion_char\fP.  The default is space, tab, newline,
-\fB\er\fP, and \fB=\fP.
-
-.Vb "char *" history_search_delimiter_chars
-The list of additional characters which can delimit a history search
-string, in addition to space, tab, \fI:\fP and \fI?\fP in the case of
-a substring search.  The default is empty.
-
-.Vb int history_quotes_inhibit_expansion
-If non-zero, single-quoted words are not scanned for the history expansion
-character.  The default value is 0.
-
-.Vb "rl_linebuf_func_t *" history_inhibit_expansion_function
-This should be set to the address of a function that takes two arguments:
-a \fBchar *\fP (\fIstring\fP)
-and an \fBint\fP index into that string (\fIi\fP).
-It should return a non-zero value if the history expansion starting at
-\fIstring[i]\fP should not be performed; zero if the expansion should
-be done.
-It is intended for use by applications like \fBbash\fP that use the history
-expansion character for additional purposes.
-By default, this variable is set to \fBNULL\fP.

-.LP
-.B readline
-will read a line from the terminal
-and return it, using
-.B prompt
-as a prompt.  If 
-.B prompt
-is \fBNULL\fP or the empty string, no prompt is issued.
-The line returned is allocated with

-the caller must free it when finished.  The line returned
-has the final newline removed, so only the text of the line
-remains.
-.LP
-.B readline
-offers editing capabilities while the user is entering the

-By default, the line editing commands
-are similar to those of emacs.
-A vi\-style line editing interface is also available.
-.LP
-This manual page describes only the most basic use of \fBreadline\fP.
-Much more functionality is available; see
-\fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP
-for additional information.
-.SH RETURN VALUE
-.LP
-.B readline
-returns the text of the line read.  A blank line
-returns the empty string.  If
-.B EOF
-is encountered while reading a line, and the line is empty,
-.B NULL
-is returned.  If an
-.B EOF
-is read with a non\-empty line, it is
-treated as a newline.
-.SH NOTATION
-.LP
-An emacs-style notation is used to denote
-keystrokes.  Control keys are denoted by C\-\fIkey\fR, e.g., C\-n
-means Control\-N.  Similarly, 
-.I meta
-keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X.  (On keyboards
-without a 
-.I meta
-key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key
-then the
-.I x
-key.  This makes ESC the \fImeta prefix\fP.
-The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP,
-or press the Escape key
-then hold the Control key while pressing the
-.I x
-key.)
-.PP
-Readline commands may be given numeric
-.IR arguments ,
-which normally act as a repeat count.  Sometimes, however, it is the
-sign of the argument that is significant.  Passing a negative argument
-to a command that acts in the forward direction (e.g., \fBkill\-line\fP)
-causes that command to act in a backward direction.  Commands whose
-behavior with arguments deviates from this are noted.
-.PP
-When a command is described as \fIkilling\fP text, the text
-deleted is saved for possible future retrieval
-(\fIyanking\fP).  The killed text is saved in a
-\fIkill ring\fP.  Consecutive kills cause the text to be
-accumulated into one unit, which can be yanked all at once. 
-Commands which do not kill text separate the chunks of text
-on the kill ring.
-.SH INITIALIZATION FILE
-.LP
-Readline is customized by putting commands in an initialization
-file (the \fIinputrc\fP file).
-The name of this file is taken from the value of the
-.B INPUTRC
-environment variable.  If that variable is unset, the default is
-.IR ~/.inputrc .
-When a program which uses the readline library starts up, the
-init file is read, and the key bindings and variables are set.
-There are only a few basic constructs allowed in the
-readline init file.  Blank lines are ignored.
-Lines beginning with a \fB#\fP are comments.
-Lines beginning with a \fB$\fP indicate conditional constructs.
-Other lines denote key bindings and variable settings.
-Each program using this library may add its own commands
-and bindings.
-.PP
-For example, placing
-.RS
-.PP
-M\-Control\-u: universal\-argument
-.RE
-or
-.RS
-C\-Meta\-u: universal\-argument
-.RE
-.sp
-into the 
-.I inputrc
-would make M\-C\-u execute the readline command
-.IR universal\-argument .
-.PP
-The following symbolic character names are recognized while
-processing key bindings:
-.IR DEL ,
-.IR ESC ,
-.IR ESCAPE ,
-.IR LFD ,
-.IR NEWLINE ,
-.IR RET ,
-.IR RETURN ,
-.IR RUBOUT ,
-.IR SPACE ,
-.IR SPC ,
-and
-.IR TAB .
-.PP
-In addition to command names, readline allows keys to be bound
-to a string that is inserted when the key is pressed (a \fImacro\fP).
-.PP
-.SS Key Bindings
-.PP
-The syntax for controlling key bindings in the
-.I inputrc
-file is simple.  All that is required is the name of the
-command or the text of a macro and a key sequence to which
-it should be bound. The name may be specified in one of two ways:
-as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
-prefixes, or as a key sequence.
-.PP
-When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP,
-.I keyname
-is the name of a key spelled out in English.  For example:
-.sp
-.RS
-Control\-u: universal\-argument
-.br
-Meta\-Rubout: backward\-kill\-word
-.br
-Control\-o: "> output"
-.RE
-.LP
-In the above example,
-.I C\-u
-is bound to the function
-.BR universal\-argument ,
-.I M-DEL
-is bound to the function
-.BR backward\-kill\-word ,
-and
-.I C\-o
-is bound to run the macro
-expressed on the right hand side (that is, to insert the text
-.if t \f(CW> output\fP
-.if n ``> output''
-into the line).
-.PP
-In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
-.B keyseq
-differs from
-.B keyname
-above in that strings denoting
-an entire key sequence may be specified by placing the sequence
-within double quotes.  Some GNU Emacs style key escapes can be
-used, as in the following example, but the symbolic character names
-are not recognized.
-.sp
-.RS
-"\eC\-u": universal\-argument
-.br
-"\eC\-x\eC\-r": re\-read\-init\-file
-.br
-"\ee[11~": "Function Key 1"
-.RE
-.PP
-In this example,
-.I C-u
-is again bound to the function
-.BR universal\-argument .
-.I "C-x C-r"
-is bound to the function
-.BR re\-read\-init\-file ,
-and 
-.I "ESC [ 1 1 ~"
-is bound to insert the text
-.if t \f(CWFunction Key 1\fP.
-.if n ``Function Key 1''.
-.PP

-key sequences is
-.RS

-.B \ex\fInnn\fP
-the character whose ASCII code is the hexadecimal value \fInnn\fP
-(one to three digits)
-.RE
-.PD
-.PP
-When entering the text of a macro, single or double quotes should
-be used to indicate a macro definition.  Unquoted text
-is assumed to be a function name.
-In the macro body, the backslash escapes described above are expanded.
-Backslash will quote any other character in the macro text,
-including " and '.
-.PP
-.B Bash
-allows the current readline key bindings to be displayed or modified
-with the
-.B bind
-builtin command.  The editing mode may be switched during interactive
-use by using the
-.B \-o
-option to the
-.B set
-builtin command.  Other programs using this library provide
-similar mechanisms.  The
-.I inputrc
-file may be edited and re-read if a program does not provide
-any other means to incorporate new bindings.
-.SS Variables
-.PP
-Readline has variables that can be used to further customize its
-behavior.  A variable may be set in the
-.I inputrc
-file with a statement of the form
-.RS
-.PP
-\fBset\fP \fIvariable\-name\fP \fIvalue\fP
-.RE
-.PP
-Except where noted, readline variables can take the values
-.B On
-or
-.B Off
-(without regard to case).
-The variables and their default values are:
-.PP
-.PD 0
-.TP
-.B bell\-style (audible)
-Controls what happens when readline wants to ring the terminal bell.
-If set to \fBnone\fP, readline never rings the bell.  If set to
-\fBvisible\fP, readline uses a visible bell if one is available.
-If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
-.TP
-.B comment\-begin (``#'')
-The string that is inserted in \fBvi\fP mode when the
-.B insert\-comment
-command is executed.
-This command is bound to
-.B M\-#
-in emacs mode and to
-.B #
-in vi command mode.
-.TP 
-.B completion\-ignore\-case (Off)
-If set to \fBOn\fP, readline performs filename matching and completion
-in a case\-insensitive fashion.
-.TP
-.B completion\-query\-items (100)
-This determines when the user is queried about viewing
-the number of possible completions
-generated by the \fBpossible\-completions\fP command.
-It may be set to any integer value greater than or equal to
-zero.  If the number of possible completions is greater than
-or equal to the value of this variable, the user is asked whether
-or not he wishes to view them; otherwise they are simply listed
-on the terminal.
-.TP
-.B convert\-meta (On)
-If set to \fBOn\fP, readline will convert characters with the
-eighth bit set to an ASCII key sequence
-by stripping the eighth bit and prefixing it with an
-escape character (in effect, using escape as the \fImeta prefix\fP).
-.TP
-.B disable\-completion (Off)
-If set to \fBOn\fP, readline will inhibit word completion.  Completion 
-characters will be inserted into the line as if they had been
-mapped to \fBself-insert\fP.
-.TP
-.B editing\-mode (emacs)
-Controls whether readline begins with a set of key bindings similar
-to emacs or vi.
-.B editing\-mode
-can be set to either
-.B emacs
-or
-.BR vi .
-.TP
-.B enable\-keypad (Off)
-When set to \fBOn\fP, readline will try to enable the application
-keypad when it is called.  Some systems need this to enable the
-arrow keys.
-.TP
-.B expand\-tilde (Off)
-If set to \fBon\fP, tilde expansion is performed when readline
-attempts word completion.
-.TP
-.B horizontal\-scroll\-mode (Off)
-When set to \fBOn\fP, makes readline use a single line for display,
-scrolling the input horizontally on a single screen line when it
-becomes longer than the screen width rather than wrapping to a new line.
-.TP
-.B input\-meta (Off)
-If set to \fBOn\fP, readline will enable eight-bit input (that is,
-it will not clear the eighth bit in the characters it reads),
-regardless of what the terminal claims it can support.  The name
-.B meta\-flag
-is a synonym for this variable.
-.TP
-.B isearch\-terminators (``C\-[ C\-J'')
-The string of characters that should terminate an incremental
-search without subsequently executing the character as a command.
-If this variable has not been given a value, the characters
-\fIESC\fP and \fIC\-J\fP will terminate an incremental search.
-.TP
-.B keymap (emacs)
-Set the current readline keymap.  The set of legal keymap names is
-\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
-vi-command\fP, and
-.IR vi-insert .
-\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is
-equivalent to \fIemacs-standard\fP.  The default value is
-.IR emacs .
-The value of
-.B editing\-mode
-also affects the default keymap.
-.TP
-.B mark\-directories (On)
-If set to \fBOn\fP, completed directory names have a slash
-appended.
-.TP
-.B mark\-modified\-lines (Off)
-If set to \fBOn\fP, history lines that have been modified are displayed
-with a preceding asterisk (\fB*\fP).
-.TP
-.B output\-meta (Off)
-If set to \fBOn\fP, readline will display characters with the
-eighth bit set directly rather than as a meta-prefixed escape
-sequence.
-.TP
-.B print\-completions\-horizontally (Off)
-If set to \fBOn\fP, readline will display completions with matches
-sorted horizontally in alphabetical order, rather than down the screen.
-.TP
-.B show\-all\-if\-ambiguous (Off)
-This alters the default behavior of the completion functions.  If
-set to
-.BR on ,
-words which have more than one possible completion cause the
-matches to be listed immediately instead of ringing the bell.
-.TP
-.B visible\-stats (Off)
-If set to \fBOn\fP, a character denoting a file's type as reported  
-by \fIstat\fP(2) is appended to the filename when listing possible
-completions.
-.PD
-.SS Conditional Constructs
-.PP
-Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key
-bindings and variable settings to be performed as the result
-of tests.  There are four parser directives used.
-.IP \fB$if\fP
-The 
-.B $if
-construct allows bindings to be made based on the
-editing mode, the terminal being used, or the application using
-readline.  The text of the test extends to the end of the line;
-no characters are required to isolate it.
-.RS
-.IP \fBmode\fP
-The \fBmode=\fP form of the \fB$if\fP directive is used to test
-whether readline is in emacs or vi mode.
-This may be used in conjunction
-with the \fBset keymap\fP command, for instance, to set bindings in
-the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if
-readline is starting out in emacs mode.
-.IP \fBterm\fP
-The \fBterm=\fP form may be used to include terminal-specific
-key bindings, perhaps to bind the key sequences output by the
-terminal's function keys.  The word on the right side of the
-.B =
-is tested against the full name of the terminal and the portion
-of the terminal name before the first \fB\-\fP.  This allows
-.I sun
-to match both
-.I sun
-and
-.IR sun\-cmd ,
-for instance.
-.IP \fBapplication\fP
-The \fBapplication\fP construct is used to include
-application-specific settings.  Each program using the readline
-library sets the \fIapplication name\fP, and an initialization
-file can test for a particular value.
-This could be used to bind key sequences to functions useful for
-a specific program.  For instance, the following command adds a
-key sequence that quotes the current or previous word in Bash:
-.sp 1
-.RS
-.nf
-\fB$if\fP Bash
-# Quote the current or previous word
-"\eC-xq": "\eeb\e"\eef\e""
-\fB$endif\fP
-.fi
-.RE
-.RE
-.IP \fB$endif\fP
-This command, as seen in the previous example, terminates an
-\fB$if\fP command.
-.IP \fB$else\fP
-Commands in this branch of the \fB$if\fP directive are executed if
-the test fails.
-.IP \fB$include\fP
-This directive takes a single filename as an argument and reads commands
-and bindings from that file.  For example, the following directive
-would read \fI/etc/inputrc\fP:
-.sp 1
-.RS
-.nf
-\fB$include\fP \^ \fI/etc/inputrc\fP
-.fi 
-.RE
-.SH SEARCHING
-.PP
-Readline provides commands for searching through the command history
-for lines containing a specified string.
-There are two search modes:
-.I incremental
-and
-.IR non-incremental .
-.PP
-Incremental searches begin before the user has finished typing the
-search string.
-As each character of the search string is typed, readline displays
-the next entry from the history matching the string typed so far.
-An incremental search requires only as many characters as needed to
-find the desired history entry.
-To search backward in the history for a particular string, type
-\fBC\-r\fP.  Typing \fBC\-s\fP searches forward through the history.
-The characters present in the value of the \fBisearch-terminators\fP
-variable are used to terminate an incremental search.
-If that variable has not been assigned a value the \fIEscape\fP and
-\fBC\-J\fP characters will terminate an incremental search.
-\fBC\-G\fP will abort an incremental search and restore the original
-line.
-When the search is terminated, the history entry containing the
-search string becomes the current line.
-.PP
-To find other matching entries in the history list, type \fBC\-s\fP or
-\fBC\-r\fP as appropriate.
-This will search backward or forward in the history for the next
-line matching the search string typed so far.
-Any other key sequence bound to a readline command will terminate
-the search and execute that command.
-For instance, a newline will terminate the search and accept
-the line, thereby executing the command from the history list.
-A movement command will terminate the search, make the last line found
-the current line, and begin editing.
-.PP
-Non-incremental searches read the entire search string before starting
-to search for matching history lines.  The search string may be
-typed by the user or be part of the contents of the current line.
-.SH EDITING COMMANDS
-.PP
-The following is a list of the names of the commands and the default
-key sequences to which they are bound.
-Command names without an accompanying key sequence are unbound by default.
-.PP
-In the following descriptions, \fIpoint\fP refers to the current cursor
-position, and \fImark\fP refers to a cursor position saved by the
-\fBset\-mark\fP command.
-The text between the point and mark is referred to as the \fIregion\fP.

-.B universal\-argument
-This is another way to specify an argument.
-If this command is followed by one or more digits, optionally with a
-leading minus sign, those digits define the argument.
-If the command is followed by digits, executing
-.B universal\-argument
-again ends the numeric argument, but is otherwise ignored.
-As a special case, if this command is immediately followed by a
-character that is neither a digit or minus sign, the argument count
-for the next command is multiplied by four.

-.B comment\-begin
-makes the current line a shell comment.
-.TP
-.B dump\-functions

-.SH DEFAULT KEY BINDINGS
-.LP
-The following is a list of the default emacs and vi bindings.
-Characters with the eighth bit set are written as M\-<character>, and
-are referred to as
-.I metafied
-characters.
-The printable ASCII characters not mentioned in the list of emacs
-standard bindings are bound to the
-.B self\-insert
-function, which just inserts the given character into the input line.
-In vi insertion mode, all characters not specifically mentioned are
-bound to
-.BR self\-insert .
-Characters assigned to signal generation by
-.IR stty (1)
-or the terminal driver, such as C-Z or C-C,
-retain that function.
-Upper and lower case metafied characters are bound to the same function in
-the emacs mode meta keymap.
-The remaining characters are unbound, which causes readline
-to ring the bell (subject to the setting of the
-.B bell\-style
-variable).
