	<p>The following paragraphs use Emacs style to
	describe the notation used to represent keystrokes.
	</p>
	<p>The text <kbd class="kbd">C-k</kbd> is read as ‘Control-K’ and describes the character
	produced when the <kbd class="key">k</kbd> key is pressed while the Control key
	is depressed.
	</p>
	<p>The text <kbd class="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 class="key">k</kbd>
	key is pressed (a <em class="dfn">meta character</em>), then both are released.
	The Meta key is labeled <kbd class="key">ALT</kbd> or <kbd class="key">Option</kbd> on many keyboards.
	On keyboards with two keys labeled <kbd class="key">ALT</kbd> (usually to either side of
	the space bar), the <kbd class="key">ALT</kbd> on the left side is generally set to
	work as a Meta key.
	One of the <kbd class="key">ALT</kbd> keys may also be configured
	as some other modifier, such as a
	Compose key for typing accented characters.
	</p>
	<p>On some keyboards, the Meta key modifier produces characters with
	the eighth bit (0200) set.
	You can use the <code class="code">enable-meta-key</code> variable
	to control whether or not it does this, if the keyboard allows it.
	On many others, the terminal or terminal emulator converts the metafied
	key to a key sequence beginning with <kbd class="key">ESC</kbd> as described in the
	next paragraph.
	</p>
	<p>If you do not have a Meta or <kbd class="key">ALT</kbd> key, or another key working as
	a Meta key, you can generally achieve the latter effect by typing <kbd class="key">ESC</kbd>
	<em class="emph">first</em>, and then typing <kbd class="key">k</kbd>.
	The <kbd class="key">ESC</kbd> character is known as the <em class="dfn">meta prefix</em>).
	</p>
	<p>Either process is known as <em class="dfn">metafying</em> the <kbd class="key">k</kbd> key.
	</p>
	<p>If your Meta key produces a key sequence with the <kbd class="key">ESC</kbd> meta prefix,
	you can make <kbd class="kbd">M-key</kbd> key bindings you specify
	(see <code class="code">Key Bindings</code> in <a class="ref" href="#Readline-Init-File-Syntax">Readline Init File Syntax</a>)
	do the same thing by setting the <code class="code">force-meta-prefix</code> variable.
	</p>
	<p>The text <kbd class="kbd">M-C-k</kbd> is read as ‘Meta-Control-k’ and describes the
	character produced by metafying <kbd class="kbd">C-k</kbd>.
	</p>
	<p>In addition, several keys have their own names.
	Specifically,
	<kbd class="key">DEL</kbd>, <kbd class="key">ESC</kbd>, <kbd class="key">LFD</kbd>, <kbd class="key">SPC</kbd>, <kbd class="key">RET</kbd>, and <kbd class="key">TAB</kbd> all
	stand for themselves when seen in this text, or in an init file
	(see <a class="pxref" href="#Readline-Init-File">Readline Init File</a>).
	If your keyboard lacks a <kbd class="key">LFD</kbd> key, typing <kbd class="key">C-j</kbd> will
	output the appropriate character.
	The <kbd class="key">RET</kbd> key may be labeled <kbd class="key">Return</kbd> or <kbd class="key">Enter</kbd> on
	some keyboards.

	<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 class="key">RET</kbd>.
	You do not have to be at the
	end of the line to press <kbd class="key">RET</kbd>; the entire line is accepted
	regardless of the location of the cursor within the line.

	<p>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 that case, you can type <kbd class="kbd">C-b</kbd> to move the cursor to the left,
	and then correct your mistake.
	Afterwards, you can move the cursor to the right with <kbd class="kbd">C-f</kbd>.
	</p>
	<p>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
	that you have inserted.
	Likewise, when you delete text behind the cursor,
	characters to the right of the cursor are ‘pulled back’ to fill in the
	blank space created by the removal of the text.
	These are the bare
	essentials for editing the text of an input line:
	</p>
	<dl class="table">
	<dt><kbd class="kbd">C-b</kbd></dt>
	<dd><p>Move back one character.

	You can undo all the way back to an empty line.
	</p></dd>
	</dl>

	<p>Depending on your configuration, the <kbd class="key">Backspace</kbd> key might be set to
	delete the character to the left of the cursor and the <kbd class="key">DEL</kbd> key set
	to delete the character underneath the cursor, like <kbd class="kbd">C-d</kbd>, rather
	than the character to the left of the cursor.

	<p>The above table describes the most basic keystrokes that you need
	in order to do editing of the input line.
	For your convenience, many other commands are available in
	addition to <kbd class="kbd">C-b</kbd>, <kbd class="kbd">C-f</kbd>, <kbd class="kbd">C-d</kbd>, and <kbd class="key">DEL</kbd>.
	Here are some commands for moving more rapidly within the line.
	</p>
	<dl class="table">
	<dt><kbd class="kbd">C-a</kbd></dt>
	<dd><p>Move to the start of the line.
	</p></dd>
	<dt><kbd class="kbd">C-e</kbd></dt>
	<dd><p>Move to the end of the line.
	</p></dd>
	<dt><kbd class="kbd">M-f</kbd></dt>
	<dd><p>Move forward a word, where a word is composed of letters and digits.
	</p></dd>
	<dt><kbd class="kbd">M-b</kbd></dt>
	<dd><p>Move backward a word.
	</p></dd>
	<dt><kbd class="kbd">C-l</kbd></dt>
	<dd><p>Clear the screen, reprinting the current line at the top.
	</p></dd>
	</dl>

	<p>Notice how <kbd class="kbd">C-f</kbd> moves forward a character, while <kbd class="kbd">M-f</kbd> moves
	forward a word.
	It is a loose convention that control keystrokes
	operate on characters while meta keystrokes operate on words.

	<a class="index-entry-id" id="index-killing-text"></a>
	<a class="index-entry-id" id="index-yanking-text"></a>

	<p><em class="dfn">Killing</em> text means to delete the text from the line, but to save
	it away for later use, usually by <em class="dfn">yanking</em> (re-inserting)
	it back into the line.
	(‘Cut’ and ‘paste’ are more recent jargon for ‘kill’ and ‘yank’.)
	</p>
	<p>If the description for a command says that it ‘kills’ text, then you can
	be sure that you can get the text back in a different (or the same)
	place later.
	</p>
	<p>When you use a kill command, the text is saved in a <em class="dfn">kill-ring</em>.
	Any number of consecutive kills save all of the killed text together, so
	that when you yank it back, you get it all.
	The kill ring is not line specific; the text that you killed on a previously
	typed line is available to be yanked back later, when you are typing
	another line.
	<a class="index-entry-id" id="index-kill-ring"></a>
	</p>
	<p>Here is the list of commands for killing text.
	</p>
	<dl class="table">
	<dt><kbd class="kbd">C-k</kbd></dt>
	<dd><p>Kill the text from the current cursor position to the end of the line.
	</p>
	</dd>
	<dt><kbd class="kbd">M-d</kbd></dt>
	<dd><p>Kill from the cursor to the end of the current word, or, if between
	words, to the end of the next word.
	Word boundaries are the same as those used by <kbd class="kbd">M-f</kbd>.
	</p>
	</dd>
	<dt><kbd class="kbd">M-<kbd class="key">DEL</kbd></kbd></dt>
	<dd><p>Kill from the cursor to the start of the current word, or, if between
	words, to the start of the previous word.
	Word boundaries are the same as those used by <kbd class="kbd">M-b</kbd>.
	</p>
	</dd>
	<dt><kbd class="kbd">C-w</kbd></dt>
	<dd><p>Kill from the cursor to the previous whitespace.
	This is different than
	<kbd class="kbd">M-<kbd class="key">DEL</kbd></kbd> because the word boundaries differ.
	</p>
	</dd>
	</dl>

	<p>Here is how to <em class="dfn">yank</em> the text back into the line. Yanking
	means to copy the most-recently-killed text from the kill buffer
	into the line at the current cursor position.
	</p>
	<dl class="table">
	<dt><kbd class="kbd">C-y</kbd></dt>
	<dd><p>Yank the most recently killed text back into the buffer at the cursor.
	</p>
	</dd>
	<dt><kbd class="kbd">M-y</kbd></dt>
	<dd><p>Rotate the kill-ring, and yank the new top.
	You can only do this if the prior command is <kbd class="kbd">C-y</kbd> or <kbd class="kbd">M-y</kbd>.
	</p></dd>
	</dl>

	<h4 class="subsection" id="Readline-Arguments-1"><span>1.2.4 Readline Arguments<a class="copiable-link" href="#Readline-Arguments-1"> ¶</a></span></h4>

	<p>You can pass numeric arguments to Readline commands.
	Sometimes the
	argument acts as a repeat count, other times it is the <i class="i">sign</i> of the
	argument that is significant.
	If you pass a negative argument to a
	command which normally acts in a forward direction, that command will
	act in a backward direction.
	For example, to kill text back to the
	start of the line, you might type ‘<samp class="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 class="samp">-</samp>’), then the sign of the argument will be negative.
	Once you have typed one meta digit to get the argument started, you can
	type the remainder of the digits, and then the command.
	For example, to give
	the <kbd class="kbd">C-d</kbd> command an argument of 10, you could type ‘<samp class="samp">M-1 0 C-d</samp>’,
	which will delete the next ten characters on the input line.

	<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.
	When using emacs editing mode, type <kbd class="kbd">C-r</kbd>
	to search backward in the history for a particular string.
	Typing <kbd class="kbd">C-s</kbd> searches forward through the history.
	The characters present in the value of the <code class="code">isearch-terminators</code> variable
	are used to terminate an incremental search.
	If that variable has not been assigned a value, the <kbd class="key">ESC</kbd> and
	<kbd class="kbd">C-j</kbd> characters terminate an incremental search.
	<kbd class="kbd">C-g</kbd> aborts an incremental search and restores 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 class="kbd">C-r</kbd> or
	<kbd class="kbd">C-s</kbd> as appropriate.
	This searches 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 terminates
	the search and executes that command.
	For instance, a <kbd class="key">RET</kbd> terminates the search and accepts
	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 class="kbd">C-r</kbd>s are typed without any intervening characters defining
	a new search string, Readline uses any remembered search string.
	</p>
	<p>Non-incremental searches read the entire search string before starting
	to search for matching history entries.
	The search string may be typed by the user or be part of the contents of
	the current line.

	<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 class="dfn">inputrc</em> file, conventionally in their home directory.
	The name of this file is taken from the value of the
	environment variable <code class="env">INPUTRC</code>.
	If that variable is unset, the default is <samp class="file">~/.inputrc</samp>.
	If that file does not exist or cannot be read, Readline looks for
	<samp class="file">/etc/inputrc</samp>.
	</p>
	<p>When a program that uses the Readline library starts up, Readline reads
	the init file and sets any variables and key bindings it contains.
	</p>
	<p>In addition, the <code class="code">C-x C-r</code> command re-reads this init file, thus
	incorporating any changes that you might have made to it.

	<dd><p>You can modify the run-time behavior of Readline by
	altering the values of variables in Readline
	using the <code class="code">set</code> command within the init file.
	The syntax is simple:
	</p>
	<div class="example">
	<pre class="example-preformatted">set <var class="var">variable</var> <var class="var">value</var>
	</pre></div>

	<p>Here, for example, is how to

	<code class="code">vi</code> line editing commands:
	</p>
	<div class="example">
	<pre class="example-preformatted">set editing-mode vi
	</pre></div>

	<p>Variable names and values, where appropriate, are recognized without
	regard to case.
	Unrecognized variable names are ignored.
	</p>
	<p>Boolean variables (those that can be set to on or off) are set to on if
	the value is null or empty, <var class="var">on</var> (case-insensitive), or 1.
	Any other value results in the variable being set to off.

	<dt>Key Bindings</dt>
	<dd><p>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>
	<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 class="var">macro</var>).
	The difference between a macro and a command is that a macro is
	enclosed in single or double quotes.

	<dd><p>The <var class="var">application</var> construct is used to include
	application-specific settings.
	Each program using the Readline
	library sets the <var class="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:
	</p><div class="example">
	<pre class="example-preformatted">$if Bash
	# Quote the current or previous word
	"\C-xq": "\eb\"\ef\""

	<dt><code class="code">variable</code></dt>
	<dd><p>The <var class="var">variable</var> construct provides simple equality tests for Readline
	variables and values.
	The permitted comparison operators are ‘<samp class="samp">=</samp>’, ‘<samp class="samp">==</samp>’, and ‘<samp class="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.
	String and boolean variables may be tested.
	Boolean variables must be
	tested against the values <var class="var">on</var> and <var class="var">off</var>.
	The following example is equivalent to the <code class="code">mode=emacs</code> test described
	above:
	</p><div class="example">

	<p>This section describes Readline commands that may be bound to key
	sequences.
	Command names without an accompanying key sequence are unbound by default.
	</p>
	<p>In the following descriptions, <em class="dfn">point</em> refers to the current cursor
	position, and <em class="dfn">mark</em> refers to a cursor position saved by the
	<code class="code">set-mark</code> command.
	The text between the point and mark is referred to as the <em class="dfn">region</em>.
	Readline
	has the concept of an <em class="emph">active region</em>:
	when the region is active,
	Readline redisplay highlights the region using the
	value of the
	<code class="code">active-region-start-color</code>
	variable.
	The <code class="code">enable-active-region</code> variable turns this on and off.
	Several commands set the region to active; those are noted below.

	<li> PREAMBLE

	<p>The purpose of this License is to make a manual, textbook, or other
	functional and useful document <em class="dfn">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>
	</li><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
	<small class="sc">ASCII</small> without markup, Texinfo input format, LaTeX input
	format, <abbr class="acronym">SGML</abbr> or <abbr class="acronym">XML</abbr> using a publicly available
	<abbr class="acronym">DTD</abbr>, and standard-conforming simple <abbr class="acronym">HTML</abbr>,
	PostScript or <abbr class="acronym">PDF</abbr> designed for human modification. Examples
	of transparent image formats include <abbr class="acronym">PNG</abbr>, <abbr class="acronym">XCF</abbr> and
	<abbr class="acronym">JPG</abbr>. Opaque formats include proprietary formats that can be
	read and edited only by proprietary word processors, <abbr class="acronym">SGML</abbr> or
	<abbr class="acronym">XML</abbr> for which the <abbr class="acronym">DTD</abbr> and/or processing tools are
	not generally available, and the machine-generated <abbr class="acronym">HTML</abbr>,
	PostScript or <abbr class="acronym">PDF</abbr> 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>
	</li><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>
	</li><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>
	</li><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>
	<ol class="enumerate" type="A" start="1">
	<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.

	</li><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.

	</li><li> State on the Title page the name of the publisher of the
	Modified Version, as the publisher.

	</li><li> Preserve all the copyright notices of the Document.

	</li><li> Add an appropriate copyright notice for your modifications
	adjacent to the other copyright notices.

	</li><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.

	</li><li> Preserve in that license notice the full lists of Invariant Sections
	and required Cover Texts given in the Document’s license notice.

	</li><li> Include an unaltered copy of this License.

	</li><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.

	</li><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.

	</li><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.

	</li><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.

	</li><li> Delete any section Entitled “Endorsements”. Such a section
	may not be included in the Modified Version.

	</li><li> Do not retitle any existing section to be Entitled “Endorsements” or
	to conflict in title with any Invariant Section.

	</li><li> Preserve any Warranty Disclaimers.
	</li></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>
	</li><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>
	</li><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>
	</li><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>
	</li><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>
	</li><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>
	</li><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 class="uref" 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>
	</li><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.
	</p>

	<p>To use this License in a document you have written, include a copy of
	the License in the document and put the following copyright and
	license notices just after the title page:
	</p>
	<div class="example smallexample">
	<div class="group"><pre class="example-preformatted"> Copyright (C) <var class="var">year</var> <var class="var">your name</var>.
	Permission is granted to copy, distribute and/or modify this document
	under the terms of the GNU Free Documentation License, Version 1.3
	or any later version published by the Free Software Foundation;
	with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
	Texts. A copy of the license is included in the section entitled ``GNU
	Free Documentation License''.
	</pre></div></div>

	<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
	replace the “with…Texts.” line with this:
	</p>
	<div class="example smallexample">
	<div class="group"><pre class="example-preformatted"> with the Invariant Sections being <var class="var">list their titles</var>, with
	the Front-Cover Texts being <var class="var">list</var>, and with the Back-Cover Texts
	being <var class="var">list</var>.
	</pre></div></div>

	<p>If you have Invariant Sections without Cover Texts, or some other
	combination of the three, merge those two alternatives to suit the
	situation.
	</p>
	<p>If your document contains nontrivial examples of program code, we
	recommend releasing these examples in parallel under your choice of
	free software license, such as the GNU General Public License,
	to permit their use in free software.
