+
+The following paragraphs describe the notation used to represent
+keystrokes.
+</P><P>
+
+The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
+produced when the <KBD>k</KBD> key is pressed while the Control key
+is depressed.
+</P><P>
+
+The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
+key is pressed.
+The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
+On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
+the space bar), the <KBD>ALT</KBD> on the left side is generally set to
+work as a Meta key.
+The <KBD>ALT</KBD> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+</P><P>
+
+If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
+<EM>first</EM>, and then typing <KBD>k</KBD>.
+Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
+</P><P>
+
+The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
+character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
+</P><P>
+
+In addition, several keys have their own names. Specifically,
+<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
+stand for themselves when seen in this text, or in an init file
+(see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
+If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
+produce the desired character.
+The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
+some keyboards.

+<!--docid::SEC3::-->
+<P>
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled. The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line. Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections. Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>. You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+In order to enter characters into the line, simply type them. The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right. If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+</P><P>
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters. In

+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text

+other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>,

+You can pass numeric arguments to Readline commands. Sometimes the
+argument acts as a repeat count, other times it is the <I>sign</I> of the
+argument that is significant. If you pass a negative argument to a

+act in a backward direction. For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+</P><P>
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command. If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative. Once

+the remainder of the digits, and then the command. For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<!--docid::SEC8::-->
+<P>
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes: <EM>incremental</EM> and <EM>non-incremental</EM>.
+</P><P>
+
+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
+<KBD>C-r</KBD>. Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> 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.
+</P><P>
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry 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 <KBD>RET</KBD> 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.
+</P><P>
+
+Readline remembers the last incremental search string. If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+</P><P>
+
+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.

+<!--docid::SEC9::-->
+<P>
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an <EM>inputrc</EM> file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>. If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>. If that
+file does not exist or cannot be read, the ultimate default is
+<TT>`/etc/inputrc'</TT>.
+</P><P>
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+</P><P>
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+the terminal's bell.
+<P>
+
+<DT><CODE>bind-tty-special-chars</CODE>
+<DD><A NAME="IDX6"></A>

+Readline equivalents.
+<P>
+
+<DT><CODE>blink-matching-paren</CODE>
+<DD><A NAME="IDX7"></A>

+<P>
+
+<DT><CODE>colored-completion-prefix</CODE>
+<DD><A NAME="IDX8"></A>
+If set to <SAMP>`on'</SAMP>, when listing completions, Readline displays the

+<DT><CODE>completion-display-width</CODE>
+<DD><A NAME="IDX11"></A>
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+<P>
+
+<DT><CODE>completion-ignore-case</CODE>
+<DD><A NAME="IDX12"></A>
+If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion

+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>completion-map-case</CODE>
+<DD><A NAME="IDX13"></A>
+If set to <SAMP>`on'</SAMP>, and <VAR>completion-ignore-case</VAR> is enabled, Readline
+treats hyphens (<SAMP>`-'</SAMP>) and underscores (<SAMP>`_'</SAMP>) as equivalent when
+performing case-insensitive filename matching and completion.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>completion-prefix-display-length</CODE>
+<DD><A NAME="IDX14"></A>
+The length in characters of the common prefix of a list of possible

+replaced with an ellipsis when displaying possible completions.
+<P>
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX15"></A>
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than or equal to this value,
+Readline will ask whether or not the user wishes to view them;
+otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+A negative value means Readline should never ask.
+The default limit is <CODE>100</CODE>.
+<P>
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX16"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence. The default value is <SAMP>`on'</SAMP>, but

+eight-bit characters.
+<P>
+
+<DT><CODE>disable-completion</CODE>
+<DD><A NAME="IDX17"></A>
+If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.

+<P>
+
+<DT><CODE>echo-control-characters</CODE>
+<DD><A NAME="IDX18"></A>
+When set to <SAMP>`on'</SAMP>, on operating systems that indicate they support it,

+keyboard. The default is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>editing-mode</CODE>
+<DD><A NAME="IDX19"></A>
+The <CODE>editing-mode</CODE> variable controls which default set of
+key bindings is used. By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs. This variable can be
+set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
+<P>
+
+<DT><CODE>emacs-mode-string</CODE>
+<DD><A NAME="IDX20"></A>
+If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when emacs editing mode is active. The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is <SAMP>`@'</SAMP>.
+<P>
+
+<DT><CODE>enable-bracketed-paste</CODE>
+<DD><A NAME="IDX21"></A>
+When set to <SAMP>`On'</SAMP>, Readline will configure the terminal in a way
+that will enable it to insert each paste into the editing buffer as a
+single string of characters, instead of treating each character as if
+it had been read from the keyboard. This can prevent pasted characters
+from being interpreted as editing commands. The default is <SAMP>`On'</SAMP>.
+<P>
+
+<DT><CODE>enable-keypad</CODE>
+<DD><A NAME="IDX22"></A>
+When set to <SAMP>`on'</SAMP>, Readline will try to enable the application

+arrow keys. The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>enable-meta-key</CODE>
+<DD>When set to <SAMP>`on'</SAMP>, Readline will try to enable any meta modifier
+key the terminal claims to support when it is called. On many terminals,

+<P>
+
+<DT><CODE>expand-tilde</CODE>
+<DD><A NAME="IDX23"></A>
+If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline

+or <CODE>next-history</CODE>. The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>history-size</CODE>
+<DD><A NAME="IDX25"></A>
+Set the maximum number of history entries saved in the history list.
+If set to zero, any existing history entries are deleted and no new entries
+are saved.
+If set to a value less than zero, the number of history entries is not
+limited.
+By default, the number of history entries is not limited.
+If an attempt is made to set <VAR>history-size</VAR> to a non-numeric value,
+the maximum number of history entries will be set to 500.
+<P>
+
+<DT><CODE>horizontal-scroll-mode</CODE>
+<DD><A NAME="IDX26"></A>
+This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>. Setting it
+to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.
+This variable is automatically set to <SAMP>`on'</SAMP> for terminals of height 1.
+By default, this variable is set to <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>input-meta</CODE>
+<DD><A NAME="IDX27"></A>
+<A NAME="IDX28"></A>
+If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support. The
+default value is <SAMP>`off'</SAMP>, but Readline will set it to <SAMP>`on'</SAMP> if the
+locale contains eight-bit characters.
+The name <CODE>meta-flag</CODE> is a synonym for this variable.
+<P>
+
+<DT><CODE>isearch-terminators</CODE>
+<DD><A NAME="IDX29"></A>
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (see section <A HREF="readline.html#SEC8">1.2.5 Searching for Commands in the History</A>).
+If this variable has not been given a value, the characters <KBD>ESC</KBD> and
+<KBD>C-J</KBD> will terminate an incremental search.
+<P>
+
+<DT><CODE>keymap</CODE>
+<DD><A NAME="IDX30"></A>
+Sets Readline's idea of the current keymap for key binding commands.
+Built-in <CODE>keymap</CODE> names are
+<CODE>emacs</CODE>,
+<CODE>emacs-standard</CODE>,
+<CODE>emacs-meta</CODE>,
+<CODE>emacs-ctlx</CODE>,
+<CODE>vi</CODE>,
+<CODE>vi-move</CODE>,
+<CODE>vi-command</CODE>, and
+<CODE>vi-insert</CODE>.
+<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE> (<CODE>vi-move</CODE> is also a
+synonym); <CODE>emacs</CODE> is equivalent to <CODE>emacs-standard</CODE>.
+Applications may add additional names.
+The default value is <CODE>emacs</CODE>.
+The value of the <CODE>editing-mode</CODE> variable also affects the
+default keymap.
+<P>
+
+<DT><CODE>keyseq-timeout</CODE>
+<DD>Specifies the duration Readline will wait for a character when reading an
+ambiguous key sequence (one that can form a complete key sequence using
+the input read so far, or can take additional input to complete a longer
+key sequence).
+If no input is received within the timeout, Readline will use the shorter
+but complete key sequence.
+Readline uses this value to determine whether or not input is
+available on the current input source (<CODE>rl_instream</CODE> by default).
+The value is specified in milliseconds, so a value of 1000 means that
+Readline will wait one second for additional input.
+If this variable is set to a value less than or equal to zero, or to a
+non-numeric value, Readline will wait until another key is pressed to
+decide which key sequence to complete.
+The default value is <CODE>500</CODE>.
+<P>
+
+<DT><CODE>mark-directories</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, completed directory names have a slash
+appended. The default is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>mark-modified-lines</CODE>
+<DD><A NAME="IDX31"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an

+This variable is <SAMP>`off'</SAMP> by default.
+<P>
+
+<DT><CODE>mark-symlinked-directories</CODE>
+<DD><A NAME="IDX32"></A>
+If set to <SAMP>`on'</SAMP>, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+<CODE>mark-directories</CODE>).
+The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>match-hidden-files</CODE>
+<DD><A NAME="IDX33"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose
+names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename
+completion.
+If set to <SAMP>`off'</SAMP>, the leading <SAMP>`.'</SAMP> must be
+supplied by the user in the filename to be completed.
+This variable is <SAMP>`on'</SAMP> by default.
+<P>
+
+<DT><CODE>menu-complete-display-prefix</CODE>
+<DD><A NAME="IDX34"></A>
+If set to <SAMP>`on'</SAMP>, menu completion displays the common prefix of the

+the list. The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>output-meta</CODE>
+<DD><A NAME="IDX35"></A>
+If set to <SAMP>`on'</SAMP>, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+The default is <SAMP>`off'</SAMP>, but Readline will set it to <SAMP>`on'</SAMP> if the
+locale contains eight-bit characters.
+<P>
+
+<DT><CODE>page-completions</CODE>
+<DD><A NAME="IDX36"></A>
+If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager
+to display a screenful of possible completions at a time.
+This variable is <SAMP>`on'</SAMP> by default.
+<P>
+
+<DT><CODE>print-completions-horizontally</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches

+<P>
+
+<DT><CODE>revert-all-at-newline</CODE>
+<DD><A NAME="IDX37"></A>
+If set to <SAMP>`on'</SAMP>, Readline will undo all changes to history lines
+before returning when <CODE>accept-line</CODE> is executed. By default,
+history lines may be modified and retain individual undo lists across
+calls to <CODE>readline</CODE>. The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>show-all-if-ambiguous</CODE>
+<DD><A NAME="IDX38"></A>
+This alters the default behavior of the completion functions. If

+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is
+simple. First you need to find the name of the command that you
+want to change. The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+<P>
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.
+There can be no space between the key name and the colon -- that will be
+interpreted as part of the key name.
+The name of the key can be expressed in different ways, depending on
+what you find most comfortable.
+</P><P>

+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a <VAR>macro</VAR>).
+</P><P>
+
+<DL COMPACT>
+<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyname</VAR> is the name of a key spelled out in English. For example:

+Meta-Rubout: backward-kill-word
+Control-o: "&#62; output"
+</pre></td></tr></table><P>
+
+In the example above, <KBD>C-u</KBD> is bound to the function
+<CODE>universal-argument</CODE>,
+<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
+<KBD>C-o</KBD> is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+<SAMP>`&#62; output'</SAMP> into the line).

+<!--docid::SEC11::-->
+<P>
+
+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.
+</P><P>
+
+<DL COMPACT>
+<DT><CODE>$if</CODE>
+<DD>The <CODE>$if</CODE> 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, after any comparison operator,
+extends to the end of the line;
+unless otherwise noted, no characters are required to isolate it.
+<P>
+
+<DL COMPACT>
+<DT><CODE>mode</CODE>
+<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
+whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
+This may be used in conjunction
+with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
+the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
+Readline is starting out in <CODE>emacs</CODE> mode.
+<P>
+
+<DT><CODE>term</CODE>
+<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys. The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>. This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+<P>
+
+<DT><CODE>version</CODE>
+<DD>The <CODE>version</CODE> test may be used to perform comparisons against
+specific Readline versions.
+The <CODE>version</CODE> expands to the current Readline version.
+The set of comparison operators includes
+<SAMP>`='</SAMP> (and <SAMP>`=='</SAMP>), <SAMP>`!='</SAMP>, <SAMP>`&#60;='</SAMP>, <SAMP>`&#62;='</SAMP>, <SAMP>`&#60;'</SAMP>,
+and <SAMP>`&#62;'</SAMP>.
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., <SAMP>`7.1'</SAMP>). If the minor version is omitted, it
+is assumed to be <SAMP>`0'</SAMP>.
+The operator may be separated from the string <CODE>version</CODE> and
+from the version number argument by whitespace.
+The following example sets a variable if the Readline version being used
+is 7.0 or newer:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if version &#62;= 7.0
+set show-mode-in-prompt on
+$endif
+</pre></td></tr></table><P>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings. Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value.
+This could be used to bind key sequences to functions useful for
+a specific program. For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table><P>
+
+<DT><CODE>variable</CODE>
+<DD>The <VAR>variable</VAR> construct provides simple equality tests for Readline
+variables and values.
+The permitted comparison operators are <SAMP>`='</SAMP>, <SAMP>`=='</SAMP>, and <SAMP>`!='</SAMP>.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values <VAR>on</VAR> and <VAR>off</VAR>.
+The following example is equivalent to the <CODE>mode=emacs</CODE> test described
+above:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if editing-mode == emacs
+set show-mode-in-prompt on
+$endif
+</pre></td></tr></table></DL>
+<P>
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+<P>
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+<P>
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
+</pre></td></tr></table></DL>

+Insert the first argument to the previous command (usually
+the second word on the previous line) at point.
+With an argument <VAR>n</VAR>,
+insert the <VAR>n</VAR>th word from the previous command (the words
+in the previous command begin with word 0). A negative argument
+inserts the <VAR>n</VAR>th word from the end of the previous command.

+<DL COMPACT>
+
+<A NAME="IDX99"></A>
+<DT><CODE><I>end-of-file</I> (usually C-d)</CODE>
+<DD><A NAME="IDX100"></A>
+The character indicating end-of-file as set, for example, by
+<CODE>stty</CODE>. If this character is read when there are no characters
+on the line, and point is at the beginning of the line, Readline
+interprets it as the end of input and returns EOF.
+<P>
+
+<A NAME="IDX101"></A>
+<DT><CODE>delete-char (C-d)</CODE>
+<DD><A NAME="IDX102"></A>
+Delete the character at point. If this function is bound to the
+same character as the tty EOF character, as <KBD>C-d</KBD>
+commonly is, see above for the effects.
+<P>
+
+<A NAME="IDX103"></A>
+<DT><CODE>backward-delete-char (Rubout)</CODE>
+<DD><A NAME="IDX104"></A>
+Delete the character behind the cursor. A numeric argument means
+to kill the characters instead of deleting them.
+<P>
+
+<A NAME="IDX105"></A>
+<DT><CODE>forward-backward-delete-char ()</CODE>
+<DD><A NAME="IDX106"></A>
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted. By default, this is not bound to a key.
+<P>
+
+<A NAME="IDX107"></A>
+<DT><CODE>quoted-insert (C-q or C-v)</CODE>
+<DD><A NAME="IDX108"></A>
+Add the next character typed to the line verbatim. This is
+how to insert key sequences like <KBD>C-q</KBD>, for example.
+<P>
+
+<A NAME="IDX109"></A>
+<DT><CODE>tab-insert (M-<KBD>TAB</KBD>)</CODE>
+<DD><A NAME="IDX110"></A>
+Insert a tab character.
+<P>
+
+<A NAME="IDX111"></A>
+<DT><CODE>self-insert (a, b, A, 1, !, <small>...</small>)</CODE>
+<DD><A NAME="IDX112"></A>
+Insert yourself.
+<P>
+
+<A NAME="IDX113"></A>
+<DT><CODE>bracketed-paste-begin ()</CODE>
+<DD><A NAME="IDX114"></A>
+This function is intended to be bound to the "bracketed paste" escape
+sequence sent by some terminals, and such a binding is assigned by default.
+It allows Readline to insert the pasted text as a single unit without treating
+each character as if it had been read from the keyboard. The characters
+are inserted as if each one was bound to <CODE>self-insert</CODE> instead of
+executing any editing commands.
+<P>
+
+Bracketed paste sets the region (the characters between point and the mark)
+to the inserted text. It uses the concept of an <EM>active mark</EM>: when the
+mark is active, Readline redisplay uses the terminal's standout mode to
+denote the region.
+</P><P>
+
+<A NAME="IDX115"></A>
+<DT><CODE>transpose-chars (C-t)</CODE>
+<DD><A NAME="IDX116"></A>
+Drag the character before the cursor forward over
+the character at the cursor, moving the
+cursor forward as well. If the insertion point
+is at the end of the line, then this
+transposes the last two characters of the line.
+Negative arguments have no effect.
+<P>
+
+<A NAME="IDX117"></A>
+<DT><CODE>transpose-words (M-t)</CODE>
+<DD><A NAME="IDX118"></A>
+Drag the word before point past the word after point,
+moving point past that word as well.
+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+<P>
+
+<A NAME="IDX119"></A>
+<DT><CODE>upcase-word (M-u)</CODE>
+<DD><A NAME="IDX120"></A>
+Uppercase the current (or following) word. With a negative argument,
+uppercase the previous word, but do not move the cursor.
+<P>
+
+<A NAME="IDX121"></A>
+<DT><CODE>downcase-word (M-l)</CODE>
+<DD><A NAME="IDX122"></A>
+Lowercase the current (or following) word. With a negative argument,
+lowercase the previous word, but do not move the cursor.
+<P>
+
+<A NAME="IDX123"></A>
+<DT><CODE>capitalize-word (M-c)</CODE>
+<DD><A NAME="IDX124"></A>
+Capitalize the current (or following) word. With a negative argument,
+capitalize the previous word, but do not move the cursor.
+<P>
+
+<A NAME="IDX125"></A>
+<DT><CODE>overwrite-mode ()</CODE>
+<DD><A NAME="IDX126"></A>
+Toggle overwrite mode. With an explicit positive numeric argument,
+switches to overwrite mode. With an explicit non-positive numeric
+argument, switches to insert mode. This command affects only
+<CODE>emacs</CODE> mode; <CODE>vi</CODE> mode does overwrite differently.
+Each call to <CODE>readline()</CODE> starts in insert mode.
+<P>
+
+In overwrite mode, characters bound to <CODE>self-insert</CODE> replace
+the text at point rather than pushing the text to the right.
+Characters bound to <CODE>backward-delete-char</CODE> replace the character
+before point with a space.

+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 <CODE>universal-argument</CODE>
+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 nor minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the
+first time makes the argument count four, a second time makes the
+argument count sixteen, and so on.
+By default, this is not bound to a key.

+<H2> 2.1 Basic Behavior </H2>
+<!--docid::SEC24::-->
+<P>
+
+Many programs provide a command line interface, such as <CODE>mail</CODE>,
+<CODE>ftp</CODE>, and <CODE>sh</CODE>. For such programs, the default behaviour of
+Readline is sufficient. This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+<CODE>gets()</CODE> or <CODE>fgets()</CODE>.
+</P><P>
+
+<A NAME="IDX219"></A>
+<A NAME="IDX220"></A>
+</P><P>
+
+The function <CODE>readline()</CODE> prints a prompt <VAR>prompt</VAR>
+and then reads and returns a single line of text from the user.
+If <VAR>prompt</VAR> is <CODE>NULL</CODE> or the empty string, no prompt is displayed.
+The line <CODE>readline</CODE> returns is allocated with <CODE>malloc()</CODE>;
+the caller should <CODE>free()</CODE> the line when it has finished with it.
+The declaration for <CODE>readline</CODE> in ANSI C is
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *readline (const char *<VAR>prompt</VAR>);</CODE>
+</pre></td></tr></table></P><P>
+
+So, one might say
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *line = readline ("Enter a line: ");</CODE>
+</pre></td></tr></table>in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+</P><P>
+
+If <CODE>readline</CODE> encounters an <CODE>EOF</CODE> while reading the line, and the
+line is empty at that point, then <CODE>(char *)NULL</CODE> is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+</P><P>
+
+Readline performs some expansion on the <VAR>prompt</VAR> before it is
+displayed on the screen. See the description of <CODE>rl_expand_prompt</CODE>
+(see section <A HREF="readline.html#SEC35">2.4.6 Redisplay</A>) for additional details, especially if <VAR>prompt</VAR>
+will contain characters that do not consume physical screen space when
+displayed.
+</P><P>
+
+If you want the user to be able to get at the line later, (with
+<KBD>C-p</KBD> for example), you must call <CODE>add_history()</CODE> to save the
+line away in a <EM>history</EM> list of such lines.
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>add_history (line)</CODE>;

+a function which usefully replaces the standard <CODE>gets()</CODE> library
+function, and has the advantage of no static buffer to overflow:

+This function gives the user the default behaviour of <KBD>TAB</KBD>
+completion: completion on file names. If you do not want Readline to
+complete on filenames, you can change the binding of the <KBD>TAB</KBD> key

+
+<CODE>rl_bind_key()</CODE> takes two arguments: <VAR>key</VAR> is the character that
+you want to bind, and <VAR>function</VAR> is the address of the function to
+call when <VAR>key</VAR> is pressed. Binding <KBD>TAB</KBD> to <CODE>rl_insert()</CODE>
+makes <KBD>TAB</KBD> insert itself.
+<CODE>rl_bind_key()</CODE> returns non-zero if <VAR>key</VAR> is not a valid
+ASCII character code (between 0 and 255).

+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs. This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+</P><P>
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file <CODE>&#60;readline/readline.h&#62;</CODE>
+in any file that uses Readline's features. Since some of the definitions
+in <CODE>readline.h</CODE> use the <CODE>stdio</CODE> library, the file
+<CODE>&#60;stdio.h&#62;</CODE> should be included before <CODE>readline.h</CODE>.
+</P><P>
+
+<CODE>readline.h</CODE> defines a C preprocessor variable that should
+be treated as an integer, <CODE>RL_READLINE_VERSION</CODE>, which may
+be used to conditionally compile application code depending on
+the installed Readline version. The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x<VAR>MMmm</VAR>. <VAR>MM</VAR> is the two-digit major
+version number; <VAR>mm</VAR> is the two-digit minor version number.
+For Readline 4.2, for example, the value of
+<CODE>RL_READLINE_VERSION</CODE> would be <CODE>0x0402</CODE>.

+<H3> 2.2.2 Writing a New Function </H3>
+<!--docid::SEC27::-->
+<P>
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+</P><P>
+
+The calling sequence for a command <CODE>foo</CODE> looks like
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int foo (int count, int key)</CODE>
+</pre></td></tr></table></P><P>
+
+where <VAR>count</VAR> is the numeric argument (or 1 if defaulted) and
+<VAR>key</VAR> is the key that invoked this function.
+</P><P>
+
+It is completely up to the function as to what should be done with the
+numeric argument. Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example). Some choose to
+ignore it. In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+</P><P>
+
+A command function should return 0 if its action completes successfully,
+and a value greater than zero if some error occurs.
+This is the convention obeyed by all of the builtin Readline bindable
+command functions.

+If your function simply inserts text once, or deletes text once, and

+undoing is already done for you automatically.
+</P><P>
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with <CODE>rl_begin_undo_group()</CODE> and

+<H2> 2.5 Readline Signal Handling </H2>
+<!--docid::SEC44::-->
+<P>
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process. They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken. There is a class of signals that can
+be sent to the process currently reading input from the keyboard. Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually.
+</P><P>
+
+Readline contains an internal signal handler that is installed for a
+number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
+<CODE>SIGHUP</CODE>,
+<CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+<CODE>readline()</CODE> was called, reset the signal handling to what it was
+before <CODE>readline()</CODE> was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a <CODE>SIGINT</CODE> is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of <CODE>rl_free_line_state()</CODE> below).
+</P><P>
+
+There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an <CODE>xterm</CODE>). The Readline <CODE>SIGWINCH</CODE>
+handler updates Readline's internal screen size information, and then calls
+any <CODE>SIGWINCH</CODE> signal handler the calling application has installed.
+Readline calls the application's <CODE>SIGWINCH</CODE> signal handler without
+resetting the terminal to its original state. If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a <CODE>longjmp</CODE> back to a main processing loop), it <EM>must</EM>
+call <CODE>rl_cleanup_after_signal()</CODE> (described below), to restore the
+terminal state.
+</P><P>
+
+When an application is using the callback interface
+(see section <A HREF="readline.html#SEC41">2.4.12 Alternate Interface</A>), Readline installs signal handlers only for
+the duration of the call to <CODE>rl_callback_read_char</CODE>. Applications
+using the callback interface should be prepared to clean up Readline's
+state if they wish to handle the signal before the line handler completes
+and restores the terminal state.
+</P><P>
+
+If an application using the callback interface wishes to have Readline
+install its signal handlers at the time the application calls
+<CODE>rl_callback_handler_install</CODE> and remove them only when a complete
+line of input has been read, it should set the
+<CODE>rl_persistent_signal_handlers</CODE> variable to a non-zero value.
+This allows an application to defer all of the handling of the signals
+Readline catches to Readline.
+Applications should use this variable with care; it can result in Readline
+catching signals and not acting on them (or allowing the application to react
+to them) until the application calls <CODE>rl_callback_read_char</CODE>. This
+can result in an application becoming less responsive to keyboard signals
+like SIGINT.
+If an application does not want or need to perform any signal handling, or
+does not need to do any processing between calls to <CODE>rl_callback_read_char</CODE>,
+setting this variable may be desirable.
+</P><P>
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received. It is important that applications change the
+values of these variables only when calling <CODE>readline()</CODE>, not in
+a signal handler, so Readline's internal signal state is not corrupted.

+<H3> 2.6.1 How Completing Works </H3>
+<!--docid::SEC46::-->
+<P>
+
+In order to complete some text, the full list of possible completions
+must be available. That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context. The Readline library provides
+the user interface to completion, and two of the most common
+completion functions: filename and username. For completing other types
+of text, you must write your own completion function. This section
+describes exactly what such functions must do, and provides an example.
+</P><P>
+
+There are three major functions used to perform completion:
+</P><P>
+
+<OL>
+<LI>
+The user-interface function <CODE>rl_complete()</CODE>. This function is
+called with the same arguments as other bindable Readline functions:
+<VAR>count</VAR> and <VAR>invoking_key</VAR>.
+It isolates the word to be completed and calls
+<CODE>rl_completion_matches()</CODE> to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+<P>
+
+<LI>
+The internal function <CODE>rl_completion_matches()</CODE> uses an
+application-supplied <EM>generator</EM> function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+<CODE>rl_completion_entry_function</CODE>.
+<P>
+
+<LI>
+The generator function is called repeatedly from
+<CODE>rl_completion_matches()</CODE>, returning a string each time. The
+arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
+<VAR>text</VAR> is the partial word to be completed. <VAR>state</VAR> is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call. The generator function returns
+<CODE>(char *)NULL</CODE> to inform <CODE>rl_completion_matches()</CODE> that there are
+no more possibilities left. Usually the generator function computes the
+list of possible completions when <VAR>state</VAR> is zero, and returns them
+one at a time on subsequent calls. Each string the generator function
+returns as a match must be allocated with <CODE>malloc()</CODE>; Readline
+frees the strings when it has finished with them.
+Such a generator function is referred to as an
+<EM>application-specific completion function</EM>.

+PREAMBLE
+<P>
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document <EM>free</EM> in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+</P><P>
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+</P><P>
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+</P><P>
+
+<LI>
+APPLICABILITY AND DEFINITIONS
+<P>
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The "Document", below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as "you". You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+</P><P>
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+</P><P>
+
+A "Secondary Section" is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+</P><P>
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+</P><P>
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+</P><P>
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called "Opaque".
+</P><P>
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input
+format, <FONT SIZE="-1">SGML</FONT> or <FONT SIZE="-1">XML</FONT> using a publicly available
+<FONT SIZE="-1">DTD</FONT>, and standard-conforming simple <FONT SIZE="-1">HTML</FONT>,
+PostScript or <FONT SIZE="-1">PDF</FONT> designed for human modification. Examples
+of transparent image formats include <FONT SIZE="-1">PNG</FONT>, <FONT SIZE="-1">XCF</FONT> and
+<FONT SIZE="-1">JPG</FONT>. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, <FONT SIZE="-1">SGML</FONT> or
+<FONT SIZE="-1">XML</FONT> for which the <FONT SIZE="-1">DTD</FONT> and/or processing tools are
+not generally available, and the machine-generated <FONT SIZE="-1">HTML</FONT>,
+PostScript or <FONT SIZE="-1">PDF</FONT> produced by some word processors for
+output purposes only.
+</P><P>
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+</P><P>
+
+The "publisher" means any person or entity that distributes copies
+of the Document to the public.
+</P><P>
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".) To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+</P><P>
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+</P><P>
+
+<LI>
+VERBATIM COPYING
+<P>
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+</P><P>
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+</P><P>
+
+<LI>
+COPYING IN QUANTITY
+<P>
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+</P><P>
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+</P><P>
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+</P><P>
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+</P><P>
+
+<LI>
+MODIFICATIONS
+<P>
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+</P><P>
+
+<OL>
+<LI>
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+<P>
+
+<LI>
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+<P>
+
+<LI>
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+<P>
+
+<LI>
+Preserve all the copyright notices of the Document.
+<P>
+
+<LI>
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+<P>
+
+<LI>
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+<P>
+
+<LI>
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+<P>
+
+<LI>
+Include an unaltered copy of this License.
+<P>
+
+<LI>
+Preserve the section Entitled "History", Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled "History" in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+<P>
+
+<LI>
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the "History" section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+<P>
+
+<LI>
+For any section Entitled "Acknowledgements" or "Dedications", Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+<P>
+
+<LI>
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+<P>
+
+<LI>
+Delete any section Entitled "Endorsements". Such a section
+may not be included in the Modified Version.
+<P>
+
+<LI>
+Do not retitle any existing section to be Entitled "Endorsements" or
+to conflict in title with any Invariant Section.
+<P>
+
+<LI>
+Preserve any Warranty Disclaimers.
+</OL>
+<P>
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+</P><P>
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+</P><P>
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+</P><P>
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+</P><P>
+
+<LI>
+COMBINING DOCUMENTS
+<P>
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+</P><P>
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+</P><P>
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all
+sections Entitled "Endorsements."
+</P><P>
+
+<LI>
+COLLECTIONS OF DOCUMENTS
+<P>
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+</P><P>
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+</P><P>
+
+<LI>
+AGGREGATION WITH INDEPENDENT WORKS
+<P>
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+</P><P>
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+</P><P>
+
+<LI>
+TRANSLATION
+<P>
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+</P><P>
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+</P><P>
+
+<LI>
+TERMINATION
+<P>
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+</P><P>
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+</P><P>
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+</P><P>
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+</P><P>
+
+<LI>
+FUTURE REVISIONS OF THIS LICENSE
+<P>
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation 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. See
+<A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.
+</P><P>
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation. If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+</P><P>
+
+<LI>
+RELICENSING
+<P>
+
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works. A
+public wiki that anybody can edit is an example of such a server. A
+"Massive Multiauthor Collaboration" (or "MMC") contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+</P><P>
+
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+</P><P>
+
+"Incorporate" means to publish or republish a Document, in whole or
+in part, as part of another Document.
+</P><P>
+
+An MMC is "eligible for relicensing" if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+</P><P>
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+<H2> ADDENDUM: How to use this License for your documents </H2>
+<!--docid::SEC51::-->
+<P>
+
+To use this License in a document you have written, include a copy of
