100: <P>
101:
102: The following paragraphs describe the notation used to represent
103: keystrokes.
104: </P><P>
105:
106: The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
107: produced when the <KBD>k</KBD> key is pressed while the Control key
108: is depressed.
109: </P><P>
110:
111: The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
112: produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
113: key is pressed.
114: The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
115: On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
116: the space bar), the <KBD>ALT</KBD> on the left side is generally set to
117: work as a Meta key.
118: The <KBD>ALT</KBD> key on the right may also be configured to work as a
119: Meta key or may be configured as some other modifier, such as a
120: Compose key for typing accented characters.
121: </P><P>
122:
123: If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
124: a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
125: <EM>first</EM>, and then typing <KBD>k</KBD>.
126: Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
127: </P><P>
128:
129: The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
130: character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
131: </P><P>
132:
133: In addition, several keys have their own names. Specifically,
134: <KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
135: stand for themselves when seen in this text, or in an init file
136: (see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
137: If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
138: produce the desired character.
139: The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
140: some keyboards.

158: <!--docid::SEC3::-->
159: <P>
160:
161: Often during an interactive session you type in a long line of text,
162: only to notice that the first word on the line is misspelled. The
163: Readline library gives you a set of commands for manipulating the text
164: as you type it in, allowing you to just fix your typo, and not forcing
165: you to retype the majority of the line. Using these editing commands,
166: you move the cursor to the place that needs correction, and delete or
167: insert the text of the corrections. Then, when you are satisfied with
168: the line, you simply press <KBD>RET</KBD>. You do not have to be at the
169: end of the line to press <KBD>RET</KBD>; the entire line is accepted
170: regardless of the location of the cursor within the line.

197: <!--docid::SEC4::-->
198: <P>
199:
200: In order to enter characters into the line, simply type them. The typed
201: character appears where the cursor was, and then the cursor moves one
202: space to the right. If you mistype a character, you can use your
203: erase character to back up and delete the mistyped character.
204: </P><P>
205:
206: Sometimes you may mistype a character, and
207: not notice the error until you have typed several other characters. In
208: that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
209: correct your mistake. Afterwards, you can move the cursor to the right
210: with <KBD>C-f</KBD>.
211: </P><P>
212:
213: When you add text in the middle of a line, you will notice that characters
214: to the right of the cursor are `pushed over' to make room for the text
215: that you have inserted. Likewise, when you delete text behind the cursor,
216: characters to the right of the cursor are `pulled back' to fill in the
217: blank space created by the removal of the text. A list of the bare
218: essentials for editing the text of an input line follows.
219: </P><P>
220:
221: <DL COMPACT>
222: <DT><KBD>C-b</KBD>
223: <DD>Move back one character.
224: <DT><KBD>C-f</KBD>

234: empty line.

236: <P>

238: (Depending on your configuration, the <KBD>Backspace</KBD> key be set to
239: delete the character to the left of the cursor and the <KBD>DEL</KBD> key set
240: to delete the character underneath the cursor, like <KBD>C-d</KBD>, rather
241: than the character to the left of the cursor.)

262: The above table describes the most basic keystrokes that you need

388: <!--docid::SEC7::-->
389: <P>
390:
391: You can pass numeric arguments to Readline commands. Sometimes the
392: argument acts as a repeat count, other times it is the <I>sign</I> of the
393: argument that is significant. If you pass a negative argument to a
394: command which normally acts in a forward direction, that command will
395: act in a backward direction. For example, to kill text back to the
396: start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
397: </P><P>
398:
399: The general way to pass numeric arguments to a command is to type meta
400: digits before the command. If the first `digit' typed is a minus
401: sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative. Once
402: you have typed one meta digit to get the argument started, you can type
403: the remainder of the digits, and then the command. For example, to give
404: the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
405: which will delete the next ten characters on the input line.

423: <!--docid::SEC8::-->
424: <P>
425:
426: Readline provides commands for searching through the command history
427: for lines containing a specified string.
428: There are two search modes: <EM>incremental</EM> and <EM>non-incremental</EM>.
429: </P><P>
430:
431: Incremental searches begin before the user has finished typing the
432: search string.
433: As each character of the search string is typed, Readline displays
434: the next entry from the history matching the string typed so far.
435: An incremental search requires only as many characters as needed to
436: find the desired history entry.
437: To search backward in the history for a particular string, type
438: <KBD>C-r</KBD>. Typing <KBD>C-s</KBD> searches forward through the history.
439: The characters present in the value of the <CODE>isearch-terminators</CODE> variable
440: are used to terminate an incremental search.
441: If that variable has not been assigned a value, the <KBD>ESC</KBD> and
442: <KBD>C-J</KBD> characters will terminate an incremental search.
443: <KBD>C-g</KBD> will abort an incremental search and restore the original line.
444: When the search is terminated, the history entry containing the
445: search string becomes the current line.
446: </P><P>
447:
448: To find other matching entries in the history list, type <KBD>C-r</KBD> or
449: <KBD>C-s</KBD> as appropriate.
450: This will search backward or forward in the history for the next
451: entry matching the search string typed so far.
452: Any other key sequence bound to a Readline command will terminate
453: the search and execute that command.
454: For instance, a <KBD>RET</KBD> will terminate the search and accept
455: the line, thereby executing the command from the history list.
456: A movement command will terminate the search, make the last line found
457: the current line, and begin editing.
458: </P><P>
459:
460: Readline remembers the last incremental search string. If two
461: <KBD>C-r</KBD>s are typed without any intervening characters defining a new
462: search string, any remembered search string is used.
463: </P><P>
464:
465: Non-incremental searches read the entire search string before starting
466: to search for matching history lines. The search string may be
467: typed by the user or be part of the contents of the current line.

486: <P>
487:
488: Although the Readline library comes with a set of Emacs-like
489: keybindings installed by default, it is possible to use a different set
490: of keybindings.
491: Any user can customize programs that use Readline by putting
492: commands in an <EM>inputrc</EM> file, conventionally in his home directory.
493: The name of this
494: file is taken from the value of the environment variable <CODE>INPUTRC</CODE>. If
495: that variable is unset, the default is <TT>`~/.inputrc'</TT>. If that
496: file does not exist or cannot be read, the ultimate default is
497: <TT>`/etc/inputrc'</TT>.
498: </P><P>
499:
500: When a program which uses the Readline library starts up, the
501: init file is read, and the key bindings are set.
502: </P><P>

504: In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus

1141: <H3> 1.3.2 Conditional Init Constructs </H3>
1142: <!--docid::SEC11::-->
1143: <P>
1144:
1145: Readline implements a facility similar in spirit to the conditional
1146: compilation features of the C preprocessor which allows key
1147: bindings and variable settings to be performed as the result
1148: of tests. There are four parser directives used.
1149: </P><P>
1150:
1151: <DL COMPACT>
1152: <DT><CODE>$if</CODE>
1153: <DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
1154: editing mode, the terminal being used, or the application using
1.1.1.2 ! misho 1155: Readline. The text of the test, after any comparison operator,
! 1156: extends to the end of the line;
! 1157: unless otherwise noted, no characters are required to isolate it.
1.1 misho 1158: <P>
1159:
1160: <DL COMPACT>
1161: <DT><CODE>mode</CODE>
1162: <DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
1163: whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
1164: This may be used in conjunction
1165: with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
1166: the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
1167: Readline is starting out in <CODE>emacs</CODE> mode.
1168: <P>
1169:
1170: <DT><CODE>term</CODE>
1171: <DD>The <CODE>term=</CODE> form may be used to include terminal-specific
1172: key bindings, perhaps to bind the key sequences output by the
1173: terminal's function keys. The word on the right side of the
1174: <SAMP>`='</SAMP> is tested against both the full name of the terminal and
1175: the portion of the terminal name before the first <SAMP>`-'</SAMP>. This
1176: allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
1177: for instance.
1178: <P>
1179:
1.1.1.2 ! misho 1180: <DT><CODE>version</CODE>
! 1181: <DD>The <CODE>version</CODE> test may be used to perform comparisons against
! 1182: specific Readline versions.
! 1183: The <CODE>version</CODE> expands to the current Readline version.
! 1184: The set of comparison operators includes
! 1185: <SAMP>`='</SAMP> (and <SAMP>`=='</SAMP>), <SAMP>`!='</SAMP>, <SAMP>`<='</SAMP>, <SAMP>`>='</SAMP>, <SAMP>`<'</SAMP>,
! 1186: and <SAMP>`>'</SAMP>.
! 1187: The version number supplied on the right side of the operator consists
! 1188: of a major version number, an optional decimal point, and an optional
! 1189: minor version (e.g., <SAMP>`7.1'</SAMP>). If the minor version is omitted, it
! 1190: is assumed to be <SAMP>`0'</SAMP>.
! 1191: The operator may be separated from the string <CODE>version</CODE> and
! 1192: from the version number argument by whitespace.
! 1193: The following example sets a variable if the Readline version being used
! 1194: is 7.0 or newer:
! 1195: <TABLE><tr><td> </td><td class=example><pre>$if version >= 7.0
! 1196: set show-mode-in-prompt on
! 1197: $endif
! 1198: </pre></td></tr></table><P>
! 1199:
1.1 misho 1200: <DT><CODE>application</CODE>
1201: <DD>The <VAR>application</VAR> construct is used to include
1202: application-specific settings. Each program using the Readline
1203: library sets the <VAR>application name</VAR>, and you can test for
1204: a particular value.
1205: This could be used to bind key sequences to functions useful for
1206: a specific program. For instance, the following command adds a
1207: key sequence that quotes the current or previous word in Bash:
1208: <TABLE><tr><td> </td><td class=example><pre>$if Bash
1209: # Quote the current or previous word
1210: "\C-xq": "\eb\"\ef\""
1211: $endif
1.1.1.2 ! misho 1212: </pre></td></tr></table><P>
! 1213:
! 1214: <DT><CODE>variable</CODE>
! 1215: <DD>The <VAR>variable</VAR> construct provides simple equality tests for Readline
! 1216: variables and values.
! 1217: The permitted comparison operators are <SAMP>`='</SAMP>, <SAMP>`=='</SAMP>, and <SAMP>`!='</SAMP>.
! 1218: The variable name must be separated from the comparison operator by
! 1219: whitespace; the operator may be separated from the value on the right hand
! 1220: side by whitespace.
! 1221: Both string and boolean variables may be tested. Boolean variables must be
! 1222: tested against the values <VAR>on</VAR> and <VAR>off</VAR>.
! 1223: The following example is equivalent to the <CODE>mode=emacs</CODE> test described
! 1224: above:
! 1225: <TABLE><tr><td> </td><td class=example><pre>$if editing-mode == emacs
! 1226: set show-mode-in-prompt on
! 1227: $endif
1.1 misho 1228: </pre></td></tr></table></DL>
1229: <P>
1230:
1231: <DT><CODE>$endif</CODE>
1232: <DD>This command, as seen in the previous example, terminates an
1233: <CODE>$if</CODE> command.
1234: <P>
1235:
1236: <DT><CODE>$else</CODE>
1237: <DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
1238: the test fails.
1239: <P>
1240:
1241: <DT><CODE>$include</CODE>
1242: <DD>This directive takes a single filename as an argument and reads commands
1243: and bindings from that file.
1244: For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
1245: <TABLE><tr><td> </td><td class=example><pre>$include /etc/inputrc
1246: </pre></td></tr></table></DL>

! 1756: <DT><CODE>bracketed-paste-begin ()</CODE>
! 1757: <DD><A NAME="IDX114"></A>
! 1758: This function is intended to be bound to the "bracketed paste" escape
! 1759: sequence sent by some terminals, and such a binding is assigned by default.
! 1760: It allows Readline to insert the pasted text as a single unit without treating
! 1761: each character as if it had been read from the keyboard. The characters
! 1762: are inserted as if each one was bound to <CODE>self-insert</CODE> instead of
! 1763: executing any editing commands.
! 1764: <P>
! 1765:
! 1766: Bracketed paste sets the region (the characters between point and the mark)
! 1767: to the inserted text. It uses the concept of an <EM>active mark</EM>: when the
! 1768: mark is active, Readline redisplay uses the terminal's standout mode to
! 1769: denote the region.

1.1 misho 1775: Drag the character before the cursor forward over
1776: the character at the cursor, moving the
1777: cursor forward as well. If the insertion point
1778: is at the end of the line, then this
1779: transposes the last two characters of the line.

2567: defined within the Readline library which allow a user program to add
2568: customized functionality to Readline.
2569: </P><P>
2570:
2571: Before declaring any functions that customize Readline's behavior, or
2572: using any functionality Readline provides in other code, an
2573: application writer should include the file <CODE><readline/readline.h></CODE>
2574: in any file that uses Readline's features. Since some of the definitions
2575: in <CODE>readline.h</CODE> use the <CODE>stdio</CODE> library, the file
2576: <CODE><stdio.h></CODE> should be included before <CODE>readline.h</CODE>.
2577: </P><P>
2578:
2579: <CODE>readline.h</CODE> defines a C preprocessor variable that should
2580: be treated as an integer, <CODE>RL_READLINE_VERSION</CODE>, which may
2581: be used to conditionally compile application code depending on
2582: the installed Readline version. The value is a hexadecimal
2583: encoding of the major and minor version numbers of the library,
2584: of the form 0x<VAR>MMmm</VAR>. <VAR>MM</VAR> is the two-digit major
2585: version number; <VAR>mm</VAR> is the two-digit minor version number.
2586: For Readline 4.2, for example, the value of
2587: <CODE>RL_READLINE_VERSION</CODE> would be <CODE>0x0402</CODE>.

2711: In order to write new functions for Readline, you need to know the

2724: </P><P>
2725:
2726: It is completely up to the function as to what should be done with the
2727: numeric argument. Some functions use it as a repeat count, some
2728: as a flag, and others to choose alternate behavior (refreshing the current
2729: line as opposed to refreshing the screen, for example). Some choose to
2730: ignore it. In general, if a
2731: function uses the numeric argument as a repeat count, it should be able
2732: to do something useful with both negative and positive arguments.
2733: At the very least, it should be aware that it can be passed a
2734: negative argument.
2735: </P><P>

4764: <H2> 2.5 Readline Signal Handling </H2>
4765: <!--docid::SEC44::-->
4766: <P>
4767:
4768: Signals are asynchronous events sent to a process by the Unix kernel,
4769: sometimes on behalf of another process. They are intended to indicate
4770: exceptional events, like a user pressing the interrupt key on his terminal,
4771: or a network connection being broken. There is a class of signals that can
4772: be sent to the process currently reading input from the keyboard. Since
4773: Readline changes the terminal attributes when it is called, it needs to
4774: perform special processing when such a signal is received in order to
4775: restore the terminal to a sane state, or provide application writers with
4776: functions to do so manually.
4777: </P><P>
4778:
4779: Readline contains an internal signal handler that is installed for a
4780: number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
4781: <CODE>SIGHUP</CODE>,
4782: <CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
4783: When one of these signals is received, the signal handler
4784: will reset the terminal attributes to those that were in effect before
4785: <CODE>readline()</CODE> was called, reset the signal handling to what it was
4786: before <CODE>readline()</CODE> was called, and resend the signal to the calling
4787: application.
4788: If and when the calling application's signal handler returns, Readline
4789: will reinitialize the terminal and continue to accept input.
4790: When a <CODE>SIGINT</CODE> is received, the Readline signal handler performs
4791: some additional work, which will cause any partially-entered line to be
4792: aborted (see the description of <CODE>rl_free_line_state()</CODE> below).
4793: </P><P>
4794:
4795: There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
4796: the kernel sends to a process whenever the terminal's size changes (for
4797: example, if a user resizes an <CODE>xterm</CODE>). The Readline <CODE>SIGWINCH</CODE>
4798: handler updates Readline's internal screen size information, and then calls
4799: any <CODE>SIGWINCH</CODE> signal handler the calling application has installed.
4800: Readline calls the application's <CODE>SIGWINCH</CODE> signal handler without
4801: resetting the terminal to its original state. If the application's signal
4802: handler does more than update its idea of the terminal size and return (for
4803: example, a <CODE>longjmp</CODE> back to a main processing loop), it <EM>must</EM>
4804: call <CODE>rl_cleanup_after_signal()</CODE> (described below), to restore the
1.1.1.2 ! misho 4805: terminal state.
! 4806: </P><P>
! 4807:
! 4808: When an application is using the callback interface
! 4809: (see section <A HREF="readline.html#SEC41">2.4.12 Alternate Interface</A>), Readline installs signal handlers only for
! 4810: the duration of the call to <CODE>rl_callback_read_char</CODE>. Applications
! 4811: using the callback interface should be prepared to clean up Readline's
! 4812: state if they wish to handle the signal before the line handler completes
! 4813: and restores the terminal state.
! 4814: </P><P>
! 4815:
! 4816: If an application using the callback interface wishes to have Readline
! 4817: install its signal handlers at the time the application calls
! 4818: <CODE>rl_callback_handler_install</CODE> and remove them only when a complete
! 4819: line of input has been read, it should set the
! 4820: <CODE>rl_persistent_signal_handlers</CODE> variable to a non-zero value.
! 4821: This allows an application to defer all of the handling of the signals
! 4822: Readline catches to Readline.
! 4823: Applications should use this variable with care; it can result in Readline
! 4824: catching signals and not acting on them (or allowing the application to react
! 4825: to them) until the application calls <CODE>rl_callback_read_char</CODE>. This
! 4826: can result in an application becoming less responsive to keyboard signals
! 4827: like SIGINT.
! 4828: If an application does not want or need to perform any signal handling, or
! 4829: does not need to do any processing between calls to <CODE>rl_callback_read_char</CODE>,
! 4830: setting this variable may be desirable.
1.1 misho 4831: </P><P>
4832:
4833: Readline provides two variables that allow application writers to
4834: control whether or not it will catch certain signals and act on them
4835: when they are received. It is important that applications change the
4836: values of these variables only when calling <CODE>readline()</CODE>, not in
4837: a signal handler, so Readline's internal signal state is not corrupted.

5105: The internal function <CODE>rl_completion_matches()</CODE> uses an
5106: application-supplied <EM>generator</EM> function to generate the list of
5107: possible matches, and then returns the array of these matches.
5108: The caller should place the address of its generator function in
5109: <CODE>rl_completion_entry_function</CODE>.
5110: <P>
5111:
5112: <LI>
5113: The generator function is called repeatedly from
5114: <CODE>rl_completion_matches()</CODE>, returning a string each time. The
5115: arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
5116: <VAR>text</VAR> is the partial word to be completed. <VAR>state</VAR> is zero the
5117: first time the function is called, allowing the generator to perform
5118: any necessary initialization, and a positive non-zero integer for
5119: each subsequent call. The generator function returns
5120: <CODE>(char *)NULL</CODE> to inform <CODE>rl_completion_matches()</CODE> that there are
5121: no more possibilities left. Usually the generator function computes the
5122: list of possible completions when <VAR>state</VAR> is zero, and returns them
5123: one at a time on subsequent calls. Each string the generator function
5124: returns as a match must be allocated with <CODE>malloc()</CODE>; Readline
5125: frees the strings when it has finished with them.
5126: Such a generator function is referred to as an
5127: <EM>application-specific completion function</EM>.

6228: The purpose of this License is to make a manual, textbook, or other

6231: with or without modifying it, either commercially or noncommercially.

6236:
6237: This License is a kind of "copyleft", which means that derivative

6240: license designed for free software.
6241: </P><P>
6242:
6243: We have designed this License in order to use it for manuals for free
6244: software, because free software needs free documentation: a free
6245: program should come with manuals providing the same freedoms that the
6246: software does. But this License is not limited to software manuals;
6247: it can be used for any textual work, regardless of subject matter or
6248: whether it is published as a printed book. We recommend this License
6249: principally for works whose purpose is instruction or reference.

6253: APPLICABILITY AND DEFINITIONS
6254: <P>
6255:
6256: This License applies to any manual or other work, in any medium, that
6257: contains a notice placed by the copyright holder saying it can be
6258: distributed under the terms of this License. Such a notice grants a
6259: world-wide, royalty-free license, unlimited in duration, to use that
6260: work under the conditions stated herein. The "Document", below,
6261: refers to any such manual or work. Any member of the public is a
6262: licensee, and is addressed as "you". You accept the license if you
6263: copy, modify or distribute the work in a way requiring permission
6264: under copyright law.
6265: </P><P>
6266:
6267: A "Modified Version" of the Document means any work containing the
6268: Document or a portion of it, either copied verbatim, or with
6269: modifications and/or translated into another language.
6270: </P><P>
6271:
6272: A "Secondary Section" is a named appendix or a front-matter section
6273: of the Document that deals exclusively with the relationship of the
6274: publishers or authors of the Document to the Document's overall
6275: subject (or to related matters) and contains nothing that could fall
6276: directly within that overall subject. (Thus, if the Document is in
6277: part a textbook of mathematics, a Secondary Section may not explain
6278: any mathematics.) The relationship could be a matter of historical
6279: connection with the subject or with related matters, or of legal,
6280: commercial, philosophical, ethical or political position regarding
6281: them.
6282: </P><P>
6283:
6284: The "Invariant Sections" are certain Secondary Sections whose titles
6285: are designated, as being those of Invariant Sections, in the notice
6286: that says that the Document is released under this License. If a
6287: section does not fit the above definition of Secondary then it is not
6288: allowed to be designated as Invariant. The Document may contain zero
6289: Invariant Sections. If the Document does not identify any Invariant
6290: Sections then there are none.
6291: </P><P>
6292:
6293: The "Cover Texts" are certain short passages of text that are listed,
6294: as Front-Cover Texts or Back-Cover Texts, in the notice that says that
6295: the Document is released under this License. A Front-Cover Text may
6296: be at most 5 words, and a Back-Cover Text may be at most 25 words.
6297: </P><P>
6298:
6299: A "Transparent" copy of the Document means a machine-readable copy,
6300: represented in a format whose specification is available to the
6301: general public, that is suitable for revising the document
6302: straightforwardly with generic text editors or (for images composed of
6303: pixels) generic paint programs or (for drawings) some widely available
6304: drawing editor, and that is suitable for input to text formatters or
6305: for automatic translation to a variety of formats suitable for input
6306: to text formatters. A copy made in an otherwise Transparent file
6307: format whose markup, or absence of markup, has been arranged to thwart
6308: or discourage subsequent modification by readers is not Transparent.
6309: An image format is not Transparent if used for any substantial amount
6310: of text. A copy that is not "Transparent" is called "Opaque".
6311: </P><P>
6312:
6313: Examples of suitable formats for Transparent copies include plain
6314: ASCII without markup, Texinfo input format, LaTeX input
6315: format, <FONT SIZE="-1">SGML</FONT> or <FONT SIZE="-1">XML</FONT> using a publicly available
6316: <FONT SIZE="-1">DTD</FONT>, and standard-conforming simple <FONT SIZE="-1">HTML</FONT>,
6317: PostScript or <FONT SIZE="-1">PDF</FONT> designed for human modification. Examples
6318: of transparent image formats include <FONT SIZE="-1">PNG</FONT>, <FONT SIZE="-1">XCF</FONT> and
6319: <FONT SIZE="-1">JPG</FONT>. Opaque formats include proprietary formats that can be
6320: read and edited only by proprietary word processors, <FONT SIZE="-1">SGML</FONT> or
6321: <FONT SIZE="-1">XML</FONT> for which the <FONT SIZE="-1">DTD</FONT> and/or processing tools are
6322: not generally available, and the machine-generated <FONT SIZE="-1">HTML</FONT>,
6323: PostScript or <FONT SIZE="-1">PDF</FONT> produced by some word processors for
6324: output purposes only.
6325: </P><P>
6326:
6327: The "Title Page" means, for a printed book, the title page itself,
6328: plus such following pages as are needed to hold, legibly, the material
6329: this License requires to appear in the title page. For works in
6330: formats which do not have any title page as such, "Title Page" means
6331: the text near the most prominent appearance of the work's title,
6332: preceding the beginning of the body of the text.
6333: </P><P>
6334:
6335: The "publisher" means any person or entity that distributes copies
6336: of the Document to the public.
6337: </P><P>
6338:
6339: A section "Entitled XYZ" means a named subunit of the Document whose
6340: title either is precisely XYZ or contains XYZ in parentheses following
6341: text that translates XYZ in another language. (Here XYZ stands for a
6342: specific section name mentioned below, such as "Acknowledgements",
6343: "Dedications", "Endorsements", or "History".) To "Preserve the Title"
6344: of such a section when you modify the Document means that it remains a
6345: section "Entitled XYZ" according to this definition.
6346: </P><P>
6347:
6348: The Document may include Warranty Disclaimers next to the notice which
6349: states that this License applies to the Document. These Warranty
6350: Disclaimers are considered to be included by reference in this
6351: License, but only as regards disclaiming warranties: any other
6352: implication that these Warranty Disclaimers may have is void and has
6353: no effect on the meaning of this License.

6357: VERBATIM COPYING
6358: <P>
6359:
6360: You may copy and distribute the Document in any medium, either
6361: commercially or noncommercially, provided that this License, the
6362: copyright notices, and the license notice saying this License applies
6363: to the Document are reproduced in all copies, and that you add no other
6364: conditions whatsoever to those of this License. You may not use
6365: technical measures to obstruct or control the reading or further
6366: copying of the copies you make or distribute. However, you may accept
6367: compensation in exchange for copies. If you distribute a large enough
6368: number of copies you must also follow the conditions in section 3.
6369: </P><P>
6370:
6371: You may also lend copies, under the same conditions stated above, and
6372: you may publicly display copies.

6375: <LI>
6376: COPYING IN QUANTITY
6377: <P>
6378:
6379: If you publish printed copies (or copies in media that commonly have
6380: printed covers) of the Document, numbering more than 100, and the
6381: Document's license notice requires Cover Texts, you must enclose the
6382: copies in covers that carry, clearly and legibly, all these Cover
6383: Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
6384: the back cover. Both covers must also clearly and legibly identify
6385: you as the publisher of these copies. The front cover must present
6386: the full title with all words of the title equally prominent and
6387: visible. You may add other material on the covers in addition.
6388: Copying with changes limited to the covers, as long as they preserve
6389: the title of the Document and satisfy these conditions, can be treated
6390: as verbatim copying in other respects.
6391: </P><P>
6392:
6393: If the required texts for either cover are too voluminous to fit
6394: legibly, you should put the first ones listed (as many as fit
6395: reasonably) on the actual cover, and continue the rest onto adjacent
6396: pages.
6397: </P><P>
6398:
6399: If you publish or distribute Opaque copies of the Document numbering
6400: more than 100, you must either include a machine-readable Transparent
6401: copy along with each Opaque copy, or state in or with each Opaque copy
6402: a computer-network location from which the general network-using
6403: public has access to download using public-standard network protocols
6404: a complete Transparent copy of the Document, free of added material.
6405: If you use the latter option, you must take reasonably prudent steps,
6406: when you begin distribution of Opaque copies in quantity, to ensure
6407: that this Transparent copy will remain thus accessible at the stated
6408: location until at least one year after the last time you distribute an
6409: Opaque copy (directly or through your agents or retailers) of that
6410: edition to the public.
6411: </P><P>
6412:
6413: It is requested, but not required, that you contact the authors of the
6414: Document well before redistributing any large number of copies, to give
6415: them a chance to provide you with an updated version of the Document.

6419: MODIFICATIONS
6420: <P>
6421:
6422: You may copy and distribute a Modified Version of the Document under
6423: the conditions of sections 2 and 3 above, provided that you release
6424: the Modified Version under precisely this License, with the Modified

6566:
6567: The combined work need only contain one copy of this License, and
6568: multiple identical Invariant Sections may be replaced with a single
6569: copy. If there are multiple Invariant Sections with the same name but

6571: adding at the end of it, in parentheses, the name of the original
6572: author or publisher of that section if known, or else a unique number.
6573: Make the same adjustment to the section titles in the list of

6590: License in the various documents with a single copy that is included in
6591: the collection, provided that you follow the rules of this License for
6592: verbatim copying of each of the documents in all other respects.

6602: AGGREGATION WITH INDEPENDENT WORKS
6603: <P>
6604:
6605: A compilation of the Document or its derivatives with other separate
6606: and independent documents or works, in or on a volume of a storage or
6607: distribution medium, is called an "aggregate" if the copyright
6608: resulting from the compilation is not used to limit the legal rights
6609: of the compilation's users beyond what the individual works permit.
6610: When the Document is included in an aggregate, this License does not
6611: apply to the other works in the aggregate which are not themselves
6612: derivative works of the Document.
6613: </P><P>
6614:
6615: If the Cover Text requirement of section 3 is applicable to these
6616: copies of the Document, then if the Document is less than one half of
6617: the entire aggregate, the Document's Cover Texts may be placed on
6618: covers that bracket the Document within the aggregate, or the
6619: electronic equivalent of covers if the Document is in electronic form.
6620: Otherwise they must appear on printed covers that bracket the whole
6621: aggregate.

6625: TRANSLATION
6626: <P>
6627:
6628: Translation is considered a kind of modification, so you may
6629: distribute translations of the Document under the terms of section 4.
6630: Replacing Invariant Sections with translations requires special
6631: permission from their copyright holders, but you may include
6632: translations of some or all Invariant Sections in addition to the
6633: original versions of these Invariant Sections. You may include a
6634: translation of this License, and all the license notices in the
6635: Document, and any Warranty Disclaimers, provided that you also include
6636: the original English version of this License and the original versions
6637: of those notices and disclaimers. In case of a disagreement between
6638: the translation and the original version of this License or a notice
6639: or disclaimer, the original version will prevail.
6640: </P><P>
6641:
6642: If a section in the Document is Entitled "Acknowledgements",
6643: "Dedications", or "History", the requirement (section 4) to Preserve
6644: its Title (section 1) will typically require changing the actual
6645: title.

6649: TERMINATION
6650: <P>

6653: except as expressly provided under this License. Any attempt
6654: otherwise to copy, modify, sublicense, or distribute it is void, and
6655: will automatically terminate your rights under this License.
6656: </P><P>
6657:
6658: However, if you cease all violation of this License, then your license
6659: from a particular copyright holder is reinstated (a) provisionally,
6660: unless and until the copyright holder explicitly and finally
6661: terminates your license, and (b) permanently, if the copyright holder
6662: fails to notify you of the violation by some reasonable means prior to
6663: 60 days after the cessation.
6664: </P><P>
6665:
6666: Moreover, your license from a particular copyright holder is
6667: reinstated permanently if the copyright holder notifies you of the
6668: violation by some reasonable means, this is the first time you have
6669: received notice of violation of this License (for any work) from that
6670: copyright holder, and you cure the violation prior to 30 days after
6671: your receipt of the notice.
6672: </P><P>
6673:
6674: Termination of your rights under this section does not terminate the
6675: licenses of parties who have received copies or rights from you under
6676: this License. If your rights have been terminated and not permanently
6677: reinstated, receipt of a copy of some or all of the same material does
6678: not give you any rights to use it.

6690: </P><P>
6691:
6692: Each version of the License is given a distinguishing version number.
6693: If the Document specifies that a particular numbered version of this
6694: License "or any later version" applies to it, you have the option of
6695: following the terms and conditions either of that specified version or
6696: of any later version that has been published (not as a draft) by the
6697: Free Software Foundation. If the Document does not specify a version
6698: number of this License, you may choose any version ever published (not
6699: as a draft) by the Free Software Foundation. If the Document
6700: specifies that a proxy can decide which future versions of this
6701: License can be used, that proxy's public statement of acceptance of a
6702: version permanently authorizes you to choose that version for the
6703: Document.
