20Preface
21
22The purpose of this document is to familiarize users with the user
23interface to Speakup, a Linux Screen Reader.  If you need instructions
24for installing or obtaining Speakup, visit the web site at
25http://linux-speakup.org/.  Speakup is a set of patches to the standard
26Linux kernel source tree.  It can be built as a series of modules, or as
27a part of a monolithic kernel.  These details are beyond the scope of
28this manual, but the user may need to be aware of the module
29capabilities, depending on how your system administrator has installed
30Speakup.  If Speakup is built as a part of a monolithic kernel, and the
31user is using a hardware synthesizer, then Speakup will be able to
32provide speech access from the time the kernel is loaded, until the time
33the system is shutdown.  This means that if you have obtained Linux
34installation media for a distribution which includes Speakup as a part
35of its kernel, you will be able, as a blind person, to install Linux
36with speech access unaided by a sighted person.  Again, these details
37are beyond the scope of this manual, but the user should be aware of
38them.  See the web site mentioned above for further details.
39
401.  Starting Speakup
41
42If your system administrator has installed Speakup to work with your
43specific synthesizer by default, then all you need to do to use Speakup
44is to boot your system, and Speakup should come up talking.  This
45assumes of course  that your synthesizer is a supported hardware
46synthesizer, and that it is either installed in or connected to your
47system, and is if necessary powered on.
48
49It is possible, however, that Speakup may have been compiled into the
50kernel with no default synthesizer.  It is even possible that your
51kernel has been compiled with support for some of the supported
52synthesizers and not others.  If you find that this is the case, and
53your synthesizer is supported but not available, complain to the person
54who compiled and installed your kernel.  Or better yet, go to the web
55site, and learn how to patch Speakup into your own kernel source, and
56build and install your own kernel.
57
58If your kernel has been compiled with Speakup, and has no default
59synthesizer set, or you would like to use a different synthesizer than
60the default one, then you may issue the following command at the boot
61prompt of your boot loader.
62
63linux speakup.synth=ltlk
64
65This command would tell Speakup to look for and use a LiteTalk or
66DoubleTalk LT at boot up.  You may replace the ltlk synthesizer keyword
67with the keyword for whatever synthesizer you wish to use.  The
68speakup.synth parameter will accept the following keywords, provided
69that support for the related synthesizers has been built into the
70kernel.
71
72acntsa -- Accent SA
73acntpc -- Accent PC
74apollo -- Apollo
75audptr -- Audapter
76bns -- Braille 'n Speak
77dectlk -- DecTalk Express (old and new, db9 serial only)
78decext -- DecTalk (old) External
79dtlk -- DoubleTalk PC
80keypc -- Keynote Gold PC
81ltlk -- DoubleTalk LT, LiteTalk, or external Tripletalk (db9 serial only)
82spkout -- Speak Out
83txprt -- Transport
84dummy -- Plain text terminal
85
86Note: Speakup does * NOT * support usb connections!  Speakup also does *
87NOT * support the internal Tripletalk!
88
89Speakup does support two other synthesizers, but because they work in
90conjunction with other software, they must be loaded as modules after
91their related software is loaded, and so are not available at boot up.
92These are as follows:
93
94decpc -- DecTalk PC (not available at boot up)
95soft -- One of several software synthesizers (not available at boot up)
96
97See the sections on loading modules and software synthesizers later in
98this manual for further details.  It should be noted here that the
99speakup.synth boot parameter will have no effect if Speakup has been
100compiled as modules.  In order for Speakup modules to be loaded during
101the boot process, such action must be configured by your system
102administrator.  This will mean that you will hear some, but not all,  of
103the bootup messages.
104
1052.  Basic operation
106
107Once you have booted the system, and if necessary, have supplied the
108proper bootup parameter for your synthesizer, Speakup will begin
109talking as soon as the kernel is loaded.  In fact, it will talk a lot!
110It will speak all the boot up messages that the kernel prints on the
111screen during the boot process.  This is because Speakup is not a
112separate screen reader, but is actually built into the operating
113system.  Since almost all console applications must print text on the
114screen using the kernel, and must get their keyboard input through the
115kernel, they are automatically handled properly by Speakup.  There are a
116few exceptions, but we'll come to those later.
117
118Note:  In this guide I will refer to the numeric keypad as the keypad.
119This is done because the speakupmap.map file referred to later in this
120manual uses the term keypad instead of numeric keypad.  Also I'm lazy
121and would rather only type one word.  So keypad it is.  Got it?  Good.
122
123Most of the Speakup review keys are located on the keypad at the far
124right of the keyboard.  The numlock key should be off, in order for these
125to work.  If you toggle the numlock on, the keypad will produce numbers,
126which is exactly what you want for spreadsheets and such.  For the
127purposes of this guide, you should have the numlock turned off, which is
128its default state at bootup.
129
130You probably won't want to listen to all the bootup messages every time
131you start your system, though it's a good idea to listen to them at
132least once, just so you'll know what kind of information is available to
133you during the boot process.  You can always review these messages after
134bootup with the command:
135
136dmesg | more
137
138In order to speed the boot process, and to silence the speaking of the
139bootup messages, just press the keypad enter key.  This key is located
140in the bottom right corner of the keypad.  Speakup will shut up and stay
141that way, until you press another key.
142
143You can check to see if the boot process has completed by pressing the 8
144key on the keypad, which reads the current line.  This also has the
145effect of starting Speakup talking again, so you can press keypad enter
146to silence it again if the boot process has not completed.
147
148When the boot process is complete, you will arrive at a "login" prompt.
149At this point, you'll need to type in your user id and password, as
150provided by your system administrator.  You will hear Speakup speak the
151letters of your user id as you type it, but not the password.  This is
152because the password is not displayed on the screen for security
153reasons.  This has nothing to do with Speakup, it's a Linux security
154feature.
155
156Once you've logged in, you can run any Linux command or program which is
157allowed by your user id.  Normal users will not be able to run programs
158which require root privileges.
159
160When you are running a program or command, Speakup will automatically
161speak new text as it arrives on the screen.  You can at any time silence
162the speech with keypad enter, or use any of the Speakup review keys.
163
164Here are some basic Speakup review keys, and a short description of what
165they do.
166
167keypad 1 -- read previous character
168keypad 2 -- read current character (pressing keypad 2 twice rapidly will speak
169	the current character phonetically)
170keypad 3 -- read next character
171keypad 4 -- read previous word
172keypad 5 -- read current word (press twice rapidly to spell the current word)
173keypad 6 -- read next word
174keypad 7 -- read previous line
175keypad 8 -- read current line (press twice rapidly to hear how much the
176	text on the current line is indented)
177keypad 9 -- read next line
178keypad period -- speak current cursor position and announce current
179	virtual console
180
181It's also worth noting that the insert key on the keypad is mapped
182as the speakup key.  Instead of pressing and releasing this key, as you
183do under DOS or Windows, you hold it like a shift key, and press other
184keys in combination with it.  For example, repeatedly holding keypad
185insert, from now on called speakup, and keypad enter will toggle the
186speaking of new text on the screen on and off.  This is not the same as
187just pressing keypad enter by itself, which just silences the speech
188until you hit another key.  When you hit speakup plus keypad enter,
189Speakup will say, "You turned me off.", or "Hey, that's better."  When
190Speakup is turned off, no new text on the screen will be spoken.  You
191can still use the reading controls to review the screen however.
192
1933.  Using the Speakup Help System
194
195In order to enter the Speakup help system, press and hold the speakup
196key (remember that this is the keypad insert key), and press the f1 key.
197You will hear the message:
198
199"Press space to leave help, cursor up or down to scroll, or a letter to
200go to commands in list."
201
202When you press the spacebar to leave the help system, you will hear:
203
204"Leaving help."
205
206While you are in the Speakup help system, you can scroll up or down
207through the list of available commands using the cursor keys.  The list
208of commands is arranged in alphabetical order.  If you wish to jump to
209commands in a specific part of the alphabet, you may press the letter of
210the alphabet you wish to jump to.
211
212You can also just explore by typing keyboard keys.  Pressing keys will
213cause Speakup to speak the command associated with that key.  For
214example, if you press the keypad 8 key, you will hear:
215
216"Keypad 8 is line, say current."
217
218You'll notice that some commands do not have keys assigned to them.
219This is because they are very infrequently used commands, and are also
220accessible through the sys system.  We'll discuss the sys system later
221in this manual.
222
223You'll also notice that some commands have two keys assigned to them.
224This is because Speakup has a built in set of alternative key bindings
225for laptop users.  The alternate speakup key is the caps lock key.  You
226can press and hold the caps lock key, while pressing an alternate
227speakup command key to activate the command.  On most laptops, the
228numeric keypad is defined as the keys in the j k l area of the keyboard.
229
230There is usually a function key which turns this keypad function on and
231off, and some other key which controls the numlock state.  Toggling the
232keypad functionality on and off can become a royal pain.  So, Speakup
233gives you a simple way to get at an alternative set of key mappings for
234your laptop.  These are also available by default on desktop systems,
235because Speakup does not know whether it is running on a desktop or
236laptop.  So you may choose which set of Speakup keys to use.  Some
237system administrators may have chosen to compile Speakup for a desktop
238system without this set of alternate key bindings, but these details are
239beyond the scope of this manual.  To use the caps lock for its normal
240purpose, hold the shift key while toggling the caps lock on and off.  We
241should note here, that holding the caps lock key and pressing the z key
242will toggle the alternate j k l keypad on and off.
243
2444.  Keys and Their Assigned Commands
245
246In this section, we'll go through a list of all the speakup keys and
247commands.  You can also get a list of commands and assigned keys from
248the help system.
249
250The following list was taken from the speakupmap.map file.  Key
251assignments are on the left of the equal sign, and the associated
252Speakup commands are on the right.  The designation "spk" means to press
253and hold the speakup key, a.k.a. keypad insert, a.k.a. caps lock, while
254pressing the other specified key.

348
3495.  The Speakup Sys System
350
351The Speakup screen reader also creates a speakup subdirectory as a part
352of the sys system.
353
354As a convenience, run as root
355
356ln -s /sys/accessibility/speakup /speakup
357
358to directly access speakup parameters from /speakup.
359You can see these entries by typing the command:
360
361ls -1 /speakup/*
362
363If you issue the above ls command, you will get back something like
364this:
365
366/speakup/attrib_bleep
367/speakup/bell_pos
368/speakup/bleep_time
369/speakup/bleeps

417
418Notice the two subdirectories of /speakup: /speakup/i18n and
419/speakup/soft.
420The i18n subdirectory is described in a later section.
421The files under /speakup/soft represent settings that are specific to the
422driver for the software synthesizer.  If you use the LiteTalk, your
423synthesizer-specific settings would be found in /speakup/ltlk.  In other words,
424a subdirectory named /speakup/KWD is created to hold parameters specific
425to the device whose keyword is KWD.
426These parameters include volume, rate, pitch, and others.
427
428In addition to using the Speakup hot keys to change such things as
429volume, pitch, and rate, you can also echo values to the appropriate
430entry in the /speakup directory.  This is very useful, since it
431lets you control Speakup parameters from within a script.  How you
432would write such scripts is somewhat beyond the scope of this manual,
433but I will include a couple of simple examples here to give you a
434general idea of what such scripts can do.
435
436Suppose for example, that you wanted to control both the punctuation
437level and the reading punctuation level at the same time.  For
438simplicity, we'll call them punc0, punc1, punc2, and punc3.  The scripts
439might look something like this:
440
441#!/bin/bash
442# punc0
443# set punc and reading punc levels to 0
444echo 0 >/speakup/punc_level
445echo 0 >/speakup/reading_punc
446echo Punctuation level set to 0.
447
448#!/bin/bash
449# punc1
450# set punc and reading punc levels to 1
451echo 1 >/speakup/punc_level
452echo 1 >/speakup/reading_punc
453echo Punctuation level set to 1.
454
455#!/bin/bash
456# punc2
457# set punc and reading punc levels to 2
458echo 2 >/speakup/punc_level
459echo 2 >/speakup/reading_punc
460echo Punctuation level set to 2.
461
462#!/bin/bash
463# punc3
464# set punc and reading punc levels to 3
465echo 3 >/speakup/punc_level
466echo 3 >/speakup/reading_punc
467echo Punctuation level set to 3.
468
469If you were to store these four small scripts in a directory in your
470path, perhaps /usr/local/bin, and set the permissions to 755 with the
471chmod command, then you could change the default reading punc and
472punctuation levels at the same time by issuing just one command.  For
473example, if you were to execute the punc3 command at your shell prompt,
474then the reading punc and punc level would both get set to 3.
475
476I should note that the above scripts were written to work with bash, but
477regardless of which shell you use, you should be able to do something
478similar.
479
480The Speakup sys system also has another interesting use.  You can echo
481Speakup parameters into the sys system in a script during system
482startup, and speakup will return to your preferred parameters every time
483the system is rebooted.
484
485Most of the Speakup sys parameters can be manipulated by a regular user
486on the system.  However, there are a few parameters that are dangerous
487enough that they should only be manipulated by the root user on your
488system.  There are even some parameters that are read only, and cannot
489be written to at all.  For example, the version entry in the Speakup
490sys system is read only.  This is because there is no reason for a user
491to tamper with the version number which is reported by Speakup.  Doing
492an ls -l on /speakup/version will return this:
493
494-r--r--r--    1 root     root            0 Mar 21 13:46 /speakup/version
495
496As you can see, the version entry in the Speakup sys system is read
497only, is owned by root, and belongs to the root group.  Doing a cat of
498/speakup/version will display the Speakup version number, like
499this:
500
501cat /speakup/version
502Speakup v-2.00 CVS: Thu Oct 21 10:38:21 EDT 2004
503synth dtlk version 1.1
504
505The display shows the Speakup version number, along with the version
506number of the driver for the current synthesizer.
507
508Looking at entries in the Speakup sys system can be useful in many
509ways.  For example, you might wish to know what level your volume is set
510at.  You could type:
511
512cat /speakup/KWD/vol
513# Replace KWD with the keyword for your synthesizer, E.G., ltlk for LiteTalk.
5145
515
516The number five which comes back is the level at which the synthesizer
517volume is set at.
518
519All the entries in the Speakup sys system are readable, some are
520writable by root only, and some are writable by everyone.  Unless you
521know what you are doing, you should probably leave the ones that are
522writable by root only alone.  Most of the names are self explanatory.
523Vol for controlling volume, pitch for pitch, inflection for pitch range, rate
524for controlling speaking rate, etc.  If you find one you aren't sure about, you
525can post a query on the Speakup list.
526
5276.  Changing Synthesizers
528
529It is possible to change to a different synthesizer while speakup is
530running.  In other words, it is not necessary to reboot the system
531in order to use a different synthesizer.  You can simply echo the
532synthesizer keyword to the /speakup/synth sys entry.
533Depending on your situation, you may wish to echo none to the synth
534sys entry, to disable speech while one synthesizer is disconnected and
535a second one is connected in its place.  Then echo the keyword for the
536new synthesizer into the synth sys entry in order to start speech
537with the newly connected synthesizer.  See the list of synthesizer
538keywords in section 1 to find the keyword which matches your synth.
539
5407.  Loading modules
541
542As mentioned earlier, Speakup can either be completely compiled into the
543kernel, with the exception of the help module, or it can be compiled as
544a series of modules.   When compiled as modules, Speakup will only be
545able to speak some of the bootup messages if your system administrator
546has configured the system to load the modules at boo time. The modules
547can  be loaded after the file systems have been checked and mounted, or
548from an initrd.  There is a third possibility.  Speakup can be compiled
549with some components built into the kernel, and others as modules.  As
550we'll see in the next section, this is particularly useful when you are
551working with software synthesizers.
552
553If Speakup is completely compiled as modules, then you must use the
554modprobe command to load Speakup.  You do this by loading the module for
555the synthesizer driver you wish to use.  The driver modules are all
556named speakup_<keyword>, where <keyword> is the keyword for the
557synthesizer you want.  So, in order to load the driver for the DecTalk
558Express, you would type the following command:
559
560modprobe speakup_dectlk
561
562Issuing this command would load the DecTalk Express driver and all other
563related Speakup modules necessary to get Speakup up and running.
564
565To completely unload Speakup, again presuming that it is entirely built
566as modules, you would give the command:
567
568modprobe -r speakup_dectlk
569
570The above command assumes you were running a DecTalk Express.  If you
571were using a different synth, then you would substitute its keyword in
572place of dectlk.
573
574If you have multiple drivers loaded, you need to unload all of them, in
575order to completely unload Speakup.
576For example, if you have loaded both the dectlk and ltlk drivers, use the
577command:
578modprobe -r speakup_dectlk speakup_ltlk
579
580You cannot unload the driver for software synthesizers when a user-space
581daemon is using /dev/softsynth.  First, kill the daemon.  Next, remove
582the driver with the command:
583modprobe -r speakup_soft
584
585Now, suppose we have a situation where the main Speakup component
586is built into the kernel, and some or all of the drivers are built as
587modules.  Since the main part of Speakup is compiled into the kernel, a
588partial Speakup sys system has been created which we can take advantage
589of by simply echoing the synthesizer keyword into the
590/speakup/synth sys entry.  This will cause the kernel to
591automatically load the appropriate driver module, and start Speakup
592talking.  To switch to another synth, just echo a new keyword to the
593synth sys entry.  For example, to load the DoubleTalk LT driver,
594you would type:
595
596echo ltlk >/speakup/synth
597
598You can use the modprobe -r command to unload driver modules, regardless
599of whether the main part of Speakup has been built into the kernel or
600not.
601
6028.  Using Software Synthesizers
603
604Using a software synthesizer requires that some other software be
605installed and running on your system.  For this reason, software
606synthesizers are not available for use at bootup, or during a system
607installation process.
608There are two freely-available solutions for software speech: Espeakup and
609Speech Dispatcher.
610These are described in subsections 8.1 and 8.2, respectively.
611
612During the rest of this section, we assume that speakup_soft is either
613built in to your kernel, or loaded as a module.
614
615If your system does not have udev installed , before you can use a
616software synthesizer, you must have created the /dev/softsynth device.
617If you have not already done so, issue the following commands as root:
618
619cd /dev
620mknod softsynth c 10 26
621
622While we are at it, we might just as well create the /dev/synth device,
623which can be used to let user space programs send information to your
624synthesizer.  To create /dev/synth, change to the /dev directory, and
625issue the following command as root:
626
627mknod synth c 10 25
628
629of both.
630
6318.1. Espeakup
632
633Espeakup is a connector between Speakup and the eSpeak software synthesizer.
634Espeakup may already be available as a package for your distribution
635of Linux.  If it is not packaged, you need to install it manually.
636You can find it in the contrib/ subdirectory of the Speakup sources.
637The filename is espeakup-$VERSION.tar.bz2, where $VERSION
638depends on the current release of Espeakup.  The Speakup 3.1.2 source
639ships with version 0.71 of Espeakup.
640The README file included with the Espeakup sources describes the process
641of manual installation.
642
643Assuming that Espeakup is installed, either by the user or by the distributor,
644follow these steps to use it.
645
646Tell Speakup to use the "soft driver:
647echo soft > /speakup/synth
648
649Finally, start the espeakup program.  There are two ways to do it.
650Both require root privileges.
651
652If Espeakup was installed as a package for your Linux distribution,
653you probably have a distribution-specific script that controls the operation
654of the daemon.  Look for a file named espeakup under /etc/init.d or
655/etc/rc.d.  Execute the following command with root privileges:
656/etc/init.d/espeakup start
657Replace init.d with rc.d, if your distribution uses scripts located under
658/etc/rc.d.
659Your distribution will also have a procedure for starting daemons at
660boot-time, so it is possible to have software speech as soon as user-space
661daemons are started by the bootup scripts.
662These procedures are not described in this document.
663
664If you built Espeakup manually, the "make install" step placed the binary
665under /usr/bin.
666Run the following command as root:
667/usr/bin/espeakup
668Espeakup should start speaking.
669
6708.2. Speech Dispatcher
671
672For this option, you must have a package called
673Speech Dispatcher running on your system, and it must be configured to
674work with one of its supported software synthesizers.
675
676Two open source synthesizers you might use are Flite and Festival.  You
677might also choose to purchase the Software DecTalk from Fonix Sales Inc.
678If you run a google search for Fonix, you'll find their web site.
679
680You can obtain a copy of Speech Dispatcher from free(b)soft at
681http://www.freebsoft.org/.  Follow the installation instructions that
682come with Speech Dispatcher in order to install and configure Speech
683Dispatcher.  You can check out the web site for your Linux distribution
684in order to get a copy of either Flite or Festival.  Your Linux
685distribution may also have a precompiled Speech Dispatcher package.
686
687Once you've installed, configured, and tested Speech Dispatcher with your
688chosen software synthesizer, you still need one more piece of software
689in order to make things work.  You need a package called speechd-up.
690You get it from the free(b)soft web site mentioned above.  After you've
691compiled and installed speechd-up, you are almost ready to begin using
692your software synthesizer.
693
694Now you can begin using your software synthesizer.  In order to do so,
695echo the soft keyword to the synth sys entry like this:
696
697echo soft >/speakup/synth
698
699Next run the speechd_up command like this:
700
701speechd_up &
702
703Your synth should now start talking, and you should be able to adjust
704the pitch, rate, etc.
705
7069.  Using The DecTalk PC Card
707
708The DecTalk PC card is an ISA card that is inserted into one of the ISA
709slots in your computer.  It requires that the DecTalk PC software be
710installed on your computer, and that the software be loaded onto the
711Dectalk PC card before it can be used.
712
713You can get the dec_pc.tgz file from the linux-speakup.org site.  The
714dec_pc.tgz file is in the ~ftp/pub/linux/speakup directory.
715
716After you have downloaded the dec_pc.tgz file, untar it in your home
717directory, and read the Readme file in the newly created dec_pc
718directory.
719
720The easiest way to get the software working is to copy the entire dec_pc
721directory into /user/local/lib.  To do this, su to root in your home
722directory, and issue the command:
723
724cp dec_pc /usr/local/lib
725
726You will need to copy the dtload command from the dec_pc directory to a
727directory in your path.  Either /usr/bin or /usr/local/bin is a good
728choice.
729
730You can now run the dtload command in order to load the DecTalk PC
731software onto the card.  After you have done this, echo the decpc
732keyword to the synth entry in the sys system like this:
733
734echo decpc >/speakup/synth
735
736Your DecTalk PC should start talking, and then you can adjust the pitch,
737rate, volume, voice, etc.  The voice entry in the Speakup sys system
738will accept a number from 0 through 7 for the DecTalk PC synthesizer,
739which will give you access to some of the DecTalk voices.
740
74110.  Using Cursor Tracking
742
743In Speakup version 2.0 and later, cursor tracking is turned on by
744default.  This means that when you are using an editor, Speakup will
745automatically speak characters as you move left and right with the
746cursor keys, and lines as you move up and down with the cursor keys.
747This is the traditional sort of cursor tracking.
748Recent versions of Speakup provide two additional ways to control the
749text that is spoken when the cursor is moved:
750"highlight tracking" and "read window."
751They are described later in this section.
752Sometimes, these modes get in your way, so you can disable cursor tracking
753altogether.
754
755You may select among the various forms of cursor tracking using the keypad
756asterisk key.
757Each time you press this key, a new mode is selected, and Speakup speaks
758the name of the new mode.  The names for the four possible states of cursor
759tracking are: "cursoring on", "highlight tracking", "read window",
760and "cursoring off."  The keypad asterisk key moves through the list of
761modes in a circular fashion.
762
763If highlight tracking is enabled, Speakup tracks highlighted text,
764rather than the cursor itself. When you move the cursor with the arrow keys,
765Speakup speaks the currently highlighted information.
766This is useful when moving through various menus and dialog boxes.
767If cursor tracking isn't helping you while navigating a menu,
768try highlight tracking.
769
770With the "read window" variety of cursor tracking, you can limit the text
771that Speakup speaks by specifying a window of interest on the screen.
772See section 15 for a description of the process of defining windows.
773When you move the cursor via the arrow keys, Speakup only speaks
774the contents of the window.  This is especially helpful when you are hearing
775superfluous speech.  Consider the following example.
776
777Suppose that you are at a shell prompt.  You use bash, and you want to
778explore your command history using the up and down arrow keys.  If you
779have enabled cursor tracking, you will hear two pieces of information.
780Speakup speaks both your shell prompt and the current entry from the
781command history.  You may not want to hear the prompt repeated
782each time you move, so you can silence it by specifying a window.  Find
783the last line of text on the screen.  Clear the current window by pressing
784the key combination speakup f3.  Use the review cursor to find the first
785character that follows your shell prompt.  Press speakup + f2 twice, to
786define a one-line window.  The boundaries of the window are the
787character following the shell prompt and the end of the line.  Now, cycle
788through the cursor tracking modes using keypad asterisk, until Speakup
789says "read window."  Move through your history using your arrow keys.
790You will notice that Speakup no longer speaks the redundant prompt.
791
792Some folks like to turn cursor tracking off while they are using the
793lynx web browser.  You definitely want to turn cursor tracking off when
794you are using the alsamixer application.  Otherwise, you won't be able
795to hear your mixer settings while you are using the arrow keys.
796
79711.  Cut and Paste
798
799One of Speakup's more useful features is the ability to cut and paste
800text on the screen.  This means that you can capture information from a
801program, and paste that captured text into a different place in the
802program, or into an entirely different program, which may even be
803running on a different console.
804
805For example, in this manual, we have made references to several web
806sites.  It would be nice if you could cut and paste these urls into your
807web browser.  Speakup does this quite nicely.  Suppose you wanted to
808past the following url into your browser:
809
810http://linux-speakup.org/
811
812Use the speakup review keys to position the reading cursor on the first
813character of the above url.  When the reading cursor is in position,
814press the keypad slash key once.  Speakup will say, "mark".  Next,
815position the reading cursor on the rightmost character of the above
816url. Press the keypad slash key once again to actually cut the text
817from the screen.  Speakup will say, "cut".  Although we call this
818cutting, Speakup does not actually delete the cut text from the screen.
819It makes a copy of the text in a special buffer for later pasting.
820
821Now that you have the url cut from the screen, you can paste it into
822your browser, or even paste the url on a command line as an argument to
823your browser.
824
825Suppose you want to start lynx and go to the Speakup site.
826
827You can switch to a different console with the alt left and right
828arrows, or you can switch to a specific console by typing alt and a
829function key.  These are not Speakup commands, just standard Linux
830console capabilities.
831
832Once you've changed to an appropriate console, and are at a shell prompt,
833type the word lynx, followed by a space.  Now press and hold the speakup
834key, while you type the keypad slash character.  The url will be pasted
835onto the command line, just as though you had typed it in.  Press the
836enter key to execute the command.
837
838The paste buffer will continue to hold the cut information, until a new
839mark and cut operation is carried out.  This means you can paste the cut
840information as many times as you like before doing another cut
841operation.
842
843You are not limited to cutting and pasting only one line on the screen.
844You can also cut and paste rectangular regions of the screen.  Just
845position the reading cursor at the top left corner of the text to be
846cut, mark it with the keypad slash key, then position the reading cursor
847at the bottom right corner of the region to be cut, and cut it with the
848keypad slash key.
849
85012.  Changing the Pronunciation of Characters
851
852Through the /speakup/i18n/characters sys entry, Speakup gives you the
853ability to change how Speakup pronounces a given character.  You could,
854for example, change how some punctuation characters are spoken.  You can
855even change how Speakup will pronounce certain letters.
856
857You may, for example, wish to change how Speakup pronounces the z
858character.  The author of Speakup, Kirk Reiser, is Canadian, and thus
859believes that the z should be pronounced zed.  If you are an American,
860you might wish to use the zee pronunciation instead of zed.  You can
861change the pronunciation of both the upper and lower case z with the
862following two commands:
863
864echo 90 zee >/speakup/characters
865echo 122 zee >/speakup/characters
866
867Let's examine the parts of the two previous commands.  They are issued
868at the shell prompt, and could be placed in a startup script.
869
870The word echo tells the shell that you want to have it display the
871string of characters that follow the word echo.  If you were to just
872type:
873
874echo hello.
875
876You would get the word hello printed on your screen as soon as you
877pressed the enter key.  In this case, we are echoing strings that we
878want to be redirected into the sys system.
879
880The numbers 90 and 122 in the above echo commands are the ascii numeric
881values for the upper and lower case z, the characters we wish to change.
882
883The string zee is the pronunciation that we want Speakup to use for the
884upper and lower case z.
885
886The > symbol redirects the output of the echo command to a file, just
887like in DOS, or at the Windows command prompt.
888
889And finally, /speakup/i18n/characters is the file entry in the sys system
890where we want the output to be directed.  Speakup looks at the numeric
891value of the character we want to change, and inserts the pronunciation
892string into an internal table.
893
894You can look at the whole table with the following command:
895
896cat /speakup/i18n/characters
897
898Speakup will then print out the entire character pronunciation table.  I
899won't display it here, but leave you to look at it at your convenience.
900
90113.  Mapping Keys
902
903Speakup has the capability of allowing you to assign or "map" keys to
904internal Speakup commands.  This section necessarily assumes you have a
905Linux kernel source tree installed, and that it has been patched and
906configured with Speakup.  How you do this is beyond the scope of this
907manual.  For this information, visit the Speakup web site at
908http://linux-speakup.org/.  The reason you'll need the kernel source
909tree patched with Speakup is that the genmap utility you'll need for
910processing keymaps is in the
911/usr/src/linux-<version_number>/drivers/char/speakup directory.  The
912<version_number> in the above directory path is the version number of
913the Linux source tree you are working with.
914
915So ok, you've gone off and gotten your kernel source tree, and patched
916and configured it.  Now you can start manipulating keymaps.
917
918You can either use the
919/usr/src/linux-<version_number>/drivers/char/speakup/speakupmap.map file
920included with the Speakup source, or you can cut and paste the copy in
921section 4 into a separate file.  If you use the one in the Speakup
922source tree, make sure you make a backup of it before you start making
923changes.  You have been warned!
924
925Suppose that you want to swap the key assignments for the Speakup
926say_last_char and the Speakup say_first_char commands.  The
927speakupmap.map lists the key mappings for these two commands as follows:
928
929spk key_pageup = say_first_char
930spk key_pagedown = say_last_char
931
932You can edit your copy of the speakupmap.map file and swap the command
933names on the right side of the = (equals) sign.  You did make a backup,
934right?  The new keymap lines would look like this:
935
936spk key_pageup = say_last_char
937spk key_pagedown = say_first_char
938
939After you edit your copy of the speakupmap.map file, save it under a new
940file name, perhaps newmap.map.  Then exit your editor and return to the
941shell prompt.
942
943You are now ready to load your keymap with your swapped key assignments.
944 Assuming that you saved your new keymap as the file newmap.map, you
945would load your keymap into the sys system like this:
946
947/usr/src/linux-<version_number>/drivers/char/speakup/genmap newmap.map
948>/speakup/keymap
949
950Remember to substitute your kernel version number for the
951<version_number> in the above command.  Also note that although the
952above command wrapped onto two lines in this document, you should type
953it all on one line.
954
955Your say first and say last characters should now be swapped.  Pressing
956speakup pagedown should read you the first non-whitespace character on
957the line your reading cursor is in, and pressing speakup pageup should
958read you the last character on the line your reading cursor is in.
959
960You should note that these new mappings will only stay in effect until
961you reboot, or until you load another keymap.
962
963One final warning.  If you try to load a partial map, you will quickly
964find that all the mappings you didn't include in your file got deleted
965from the working map.  Be extremely careful, and always make a backup!
966You have been warned!
967
96814.  Internationalizing Speakup
969
970Speakup indicates various conditions to the user by speaking messages.
971For instance, when you move to the left edge of the screen with the
972review keys, Speakup says, "left."
973Prior to version 3.1.0 of Speakup, all of these messages were in English,
974and they could not be changed.  If you used a non-English synthesizer,
975you still heard English messages, such as "left" and "cursoring on."
976In version 3.1.0 or higher, one may load translations for the various
977messages via the /sys filesystem.
978
979The directory /speakup/i18n contains several collections of messages.
980Each group of messages is stored in its own file.
981The following section lists all of these files, along with a brief description
982of each.
983
98414.1.  Files Under the i18n Subdirectory
985
986* announcements:
987This file contains various general announcements, most of which cannot
988be categorized.  You will find messages such as "You killed Speakup",
989"I'm alive", "leaving help", "parked", "unparked", and others.
990You will also find the names of the screen edges and cursor tracking modes
991here.
992
993* characters:
994See section 12 for a description of this file.
995
996* chartab:
997See section 12.  Unlike the rest of the files in the i18n subdirectory,
998this one does not contain messages to be spoken.
999
1000* colors:
1001When you use the "say attributes" function, Speakup says the name of the
1002foreground and background colors.  These names come from the i18n/colors
1003file.
1004
1005* ctl_keys:
1006Here, you will find names of control keys.  These are used with Speakup's
1007say_control feature.
1008
1009* formatted:
1010This group of messages contains embedded formatting codes, to specify
1011the type and width of displayed data.  If you change these, you must
1012preserve all of the formatting codes, and they must appear in the order
1013used by the default messages.
1014
1015* function_names:
1016Here, you will find a list of names for Speakup functions.  These are used
1017by the help system.  For example, suppose that you have activated help mode,
1018and you pressed keypad 3.  Speakup says:
1019"keypad 3 is character, say next."
1020The message "character, say next" names a Speakup function, and it
1021comes from this function_names file.
1022
1023* key_names:
1024Again, key_names is used by Speakup's help system.  In the previous
1025example, Speakup said that you pressed "keypad 3."
1026This name came from the key_names file.
1027
1028* states:
1029This file contains names for key states.
1030Again, these are part of the help system.  For instance, if you had pressed
1031speakup + keypad 3, you would hear:
1032"speakup keypad 3 is go to bottom edge."
1033The speakup key is depressed, so the name of the key state is speakup.
1034This part of the message comes from the states collection.
1035

1040The files under the i18n subdirectory all follow the same format.
1041They consist of lines, with one message per line.
1042Each message is represented by a number, followed by the text of the message.
1043The number is the position of the message in the given collection.
1044For example, if you view the file /speakup/i18n/colors, you will see the
1045following list:
1046
10470	black
10481	blue
10492	green
10503	cyan
10514	red
10525	magenta
10536	yellow
10547	white
10558	grey
1056
1057You can change one message, or you can change a whole group.
1058To load a whole collection of messages from a new source, simply use
1059the cp command:
1060cp ~/my_colors /speakup/i18n/colors
1061You can change an individual message with the echo command,
1062as shown in the following example.
1063
1064The Spanish name for the color blue is azul.
1065Looking at the colors file, we see that the name "blue" is at position 1
1066within the colors group.  Let's change blue to azul:
1067echo '1 azul' > /speakup/i18n/colors
1068The next time that Speakup says message 1 from the colors group, it will
1069say "azul", rather than "blue."
1070
107114.2.2. Choose a language
1072
1073In the future, translations into various languages will be made available,
1074and most users will just load the files necessary for their language. So far,
1075only French language is available beyond native Canadian English language.
1076
1077French is only available after you are logged in.
1078
1079Canadian English is the default language. To toggle another language,
1080download the source of Speakup and untar it in your home directory. The
1081following command should let you do this:
1082
1083tar xvjf speakup-<version>.tar.bz2
1084
1085where <version> is the version number of the application.
1086
1087Next, change to the newly created directory, then into the tools/ directory, and
1088run the script speakup_setlocale. You are asked the language that you want to
1089use. Type the number associated to your language (e.g. fr for French) then press
1090Enter. Needed files are copied in the i18n directory.
1091
1092Note: the speakupconf must be installed on your system so that settings are saved.
1093Otherwise, you will have an error: your language will be loaded but you will
1094have to run the script again every time Speakup restarts.
1095See section 16.1. for information about speakupconf.
1096
1097You will have to repeat these steps for any change of locale, i.e. if you wish
1098change the speakup's language or charset (iso-8859-15 ou UTF-8).
1099
1100If you wish store the settings, note that at your next login, you will need to
1101do:
1102
1103speakup load
1104
1105Alternatively, you can add the above line to your file
1106~/.bashrc or ~/.bash_profile.
1107
1108If your system administrator ran himself the script, all the users will be able
1109to change from English to the language choosed by root and do directly
1110speakupconf load (or add this to the ~/.bashrc or
1111~/.bash_profile file). If there are several languages to handle, the
1112administrator (or every user) will have to run the first steps until speakupconf
1113save, choosing the appropriate language, in every user's home directory. Every
1114user will then be able to do speakupconf load, Speakup will load his own settings.
1115
111614.3.  No Support for Non-Western-European Languages
1117
1118As of the current release, Speakup only supports Western European languages.
1119Support for the extended characters used by languages outside of the Western
1120European family of languages is a work in progress.
1121
112215.  Using Speakup's Windowing Capability
1123
1124Speakup has the capability of defining and manipulating windows on the
1125screen.  Speakup uses the term "Window", to mean a user defined area of
1126the screen.  The key strokes for defining and manipulating Speakup
1127windows are as follows:
1128
1129speakup + f2 -- Set the bounds of the window.
1130Speakup + f3 -- clear the current window definition.
1131speakup + f4 -- Toggle window silence on and off.
1132speakup + keypad plus -- Say the currently defined window.
1133
1134These capabilities are useful for tracking a certain part of the screen
1135without rereading the whole screen, or for silencing a part of the
1136screen that is constantly changing, such as a clock or status line.
1137
1138There is no way to save these window settings, and you can only have one
1139window defined for each virtual console.  There is also no way to have
1140windows automatically defined for specific applications.
1141
1142In order to define a window, use the review keys to move your reading
1143cursor to the beginning of the area you want to define.  Then press
1144speakup + f2.  Speakup will tell you that the window starts at the
1145indicated row and column position.  Then move the reading cursor to the
1146end of the area to be defined as a window, and press speakup + f2 again.
1147 If there is more than one line in the window, Speakup will tell you
1148that the window ends at the indicated row and column position.  If there
1149is only one line in the window, then Speakup will tell you that the
1150window is the specified line on the screen.  If you are only defining a
1151one line window, you can just press speakup + f2 twice after placing the
1152reading cursor on the line you want to define as a window.  It is not
1153necessary to position the reading cursor at the end of the line in order
1154to define the whole line as a window.
1155
115616.  Tools for Controlling Speakup
1157
1158The speakup distribution includes extra tools (in the tools directory)
1159which were written to make speakup easier to use.  This section will
1160briefly describe the use of these tools.
1161
116216.1.  Speakupconf
1163
1164speakupconf began life as a contribution from Steve Holmes, a member of
1165the speakup community.  We would like to thank him for his work on the
1166early versions of this project.
1167
1168This script may be installed as part of your linux distribution, but if
1169it isn't, the recommended places to put it are /usr/local/bin or
1170/usr/bin.  This script can be run by any user, so it does not require
1171root privileges.
1172
1173Speakupconf allows you to save and load your Speakup settings.  It works
1174by reading and writing the /sys files described above.
1175
1176The directory that speakupconf uses to store your settings depends on
1177whether it is run from the root account.  If you execute speakupconf as
1178root, it uses the directory /etc/speakup.  Otherwise, it uses the directory
1179~/.speakup, where ~ is your home directory.
1180Anyone who needs to use Speakup from your console can load his own custom
1181settings with this script.
1182
1183speakupconf takes one required argument: load or save.
1184Use the command
1185speakupconf save
1186to save your Speakup settings, and
1187speakupconf load
1188to load them into Speakup.
1189A second argument may be specified to use an alternate directory to
1190load or save the speakup parameters.
1191
119216.2.  Talkwith
1193
1194Charles Hallenbeck, another member of the speakup community, wrote the
1195initial versions of this script, and we would also like to thank him for
1196his work on it.
1197
1198This script needs root privileges to run, so if it is not installed as
1199part of your linux distribution, the recommended places to install it
1200are /usr/local/sbin or /usr/sbin.
1201
1202Talkwith allows you to switch synthesizers on the fly.  It takes a synthesizer
1203name as an argument.  For instance,
1204talkwith dectlk
1205causes Speakup to use the DecTalk Express.  If you wish to switch to a
1206software synthesizer, you must also indicate which daemon you wish to
1207use.  There are two possible choices:
1208spd and espeakup.  spd is an abbreviation for speechd-up.
1209If you wish to use espeakup for software synthesis, give the command
1210talkwith soft espeakup
1211To use speechd-up, type:
1212talkwith soft spd
1213Any arguments that follow the name of the daemon are passed to the daemon
1214when it is invoked.  For instance:
1215talkwith espeakup --default-voice=fr
1216causes espeakup to use the French voice.
1217Note that talkwith must always be executed with root privileges.
1218
1219Talkwith does not attempt to load your settings after the new
1220synthesizer is activated.  You can use speakupconf to load your settings
1221if desired.

1227 Copyright (C) 2000,2001,2002  Free Software Foundation, Inc.
1228 Everyone is permitted to copy and distribute verbatim copies
1229 of this license document, but changing it is not allowed.

1231
12320. PREAMBLE
1233
1234The purpose of this License is to make a manual, textbook, or other
1235functional and useful document "free" in the sense of freedom: to
1236assure everyone the effective freedom to copy and redistribute it,
1237with or without modifying it, either commercially or noncommercially.
1238Secondarily, this License preserves for the author and publisher a way
1239to get credit for their work, while not being considered responsible
1240for modifications made by others.
1241
1242This License is a kind of "copyleft", which means that derivative
1243works of the document must themselves be free in the same sense.  It
1244complements the GNU General Public License, which is a copyleft
1245license designed for free software.
1246
1247We have designed this License in order to use it for manuals for free
1248software, because free software needs free documentation: a free
1249program should come with manuals providing the same freedoms that the
1250software does.  But this License is not limited to software manuals;
1251it can be used for any textual work, regardless of subject matter or
1252whether it is published as a printed book.  We recommend this License
1253principally for works whose purpose is instruction or reference.
1254
1255
12561. APPLICABILITY AND DEFINITIONS
1257
1258This License applies to any manual or other work, in any medium, that
1259contains a notice placed by the copyright holder saying it can be
1260distributed under the terms of this License.  Such a notice grants a
1261world-wide, royalty-free license, unlimited in duration, to use that
1262work under the conditions stated herein.  The "Document", below,
1263refers to any such manual or work.  Any member of the public is a
1264licensee, and is addressed as "you".  You accept the license if you
1265copy, modify or distribute the work in a way requiring permission
1266under copyright law.
1267
1268A "Modified Version" of the Document means any work containing the
1269Document or a portion of it, either copied verbatim, or with
1270modifications and/or translated into another language.
1271
1272A "Secondary Section" is a named appendix or a front-matter section of
1273the Document that deals exclusively with the relationship of the
1274publishers or authors of the Document to the Document's overall subject
1275(or to related matters) and contains nothing that could fall directly
1276within that overall subject.  (Thus, if the Document is in part a
1277textbook of mathematics, a Secondary Section may not explain any
1278mathematics.)  The relationship could be a matter of historical
1279connection with the subject or with related matters, or of legal,
1280commercial, philosophical, ethical or political position regarding
1281them.
1282
1283The "Invariant Sections" are certain Secondary Sections whose titles
1284are designated, as being those of Invariant Sections, in the notice
1285that says that the Document is released under this License.  If a
1286section does not fit the above definition of Secondary then it is not
1287allowed to be designated as Invariant.  The Document may contain zero
1288Invariant Sections.  If the Document does not identify any Invariant
1289Sections then there are none.
1290
1291The "Cover Texts" are certain short passages of text that are listed,
1292as Front-Cover Texts or Back-Cover Texts, in the notice that says that
1293the Document is released under this License.  A Front-Cover Text may
1294be at most 5 words, and a Back-Cover Text may be at most 25 words.
1295
1296A "Transparent" copy of the Document means a machine-readable copy,
1297represented in a format whose specification is available to the
1298general public, that is suitable for revising the document
1299straightforwardly with generic text editors or (for images composed of
1300pixels) generic paint programs or (for drawings) some widely available
1301drawing editor, and that is suitable for input to text formatters or
1302for automatic translation to a variety of formats suitable for input
1303to text formatters.  A copy made in an otherwise Transparent file
1304format whose markup, or absence of markup, has been arranged to thwart
1305or discourage subsequent modification by readers is not Transparent.
1306An image format is not Transparent if used for any substantial amount
1307of text.  A copy that is not "Transparent" is called "Opaque".
1308
1309Examples of suitable formats for Transparent copies include plain
1310ASCII without markup, Texinfo input format, LaTeX input format, SGML
1311or XML using a publicly available DTD, and standard-conforming simple
1312HTML, PostScript or PDF designed for human modification.  Examples of
1313transparent image formats include PNG, XCF and JPG.  Opaque formats
1314include proprietary formats that can be read and edited only by
1315proprietary word processors, SGML or XML for which the DTD and/or
1316processing tools are not generally available, and the
1317machine-generated HTML, PostScript or PDF produced by some word
1318processors for output purposes only.
1319
1320The "Title Page" means, for a printed book, the title page itself,
1321plus such following pages as are needed to hold, legibly, the material
1322this License requires to appear in the title page.  For works in
1323formats which do not have any title page as such, "Title Page" means
1324the text near the most prominent appearance of the work's title,
1325preceding the beginning of the body of the text.
1326
1327A section "Entitled XYZ" means a named subunit of the Document whose
1328title either is precisely XYZ or contains XYZ in parentheses following
1329text that translates XYZ in another language.  (Here XYZ stands for a
1330specific section name mentioned below, such as "Acknowledgements",
1331"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
1332of such a section when you modify the Document means that it remains a
1333section "Entitled XYZ" according to this definition.
1334
1335The Document may include Warranty Disclaimers next to the notice which
1336states that this License applies to the Document.  These Warranty
1337Disclaimers are considered to be included by reference in this
1338License, but only as regards disclaiming warranties: any other
1339implication that these Warranty Disclaimers may have is void and has
1340no effect on the meaning of this License.
1341
1342
13432. VERBATIM COPYING
1344
1345You may copy and distribute the Document in any medium, either
1346commercially or noncommercially, provided that this License, the
1347copyright notices, and the license notice saying this License applies
1348to the Document are reproduced in all copies, and that you add no other
1349conditions whatsoever to those of this License.  You may not use
1350technical measures to obstruct or control the reading or further
1351copying of the copies you make or distribute.  However, you may accept
1352compensation in exchange for copies.  If you distribute a large enough
1353number of copies you must also follow the conditions in section 3.
1354
1355You may also lend copies, under the same conditions stated above, and
1356you may publicly display copies.
1357
1358
13593. COPYING IN QUANTITY
1360
1361If you publish printed copies (or copies in media that commonly have
1362printed covers) of the Document, numbering more than 100, and the
1363Document's license notice requires Cover Texts, you must enclose the
1364copies in covers that carry, clearly and legibly, all these Cover
1365Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
1366the back cover.  Both covers must also clearly and legibly identify
1367you as the publisher of these copies.  The front cover must present
1368the full title with all words of the title equally prominent and
1369visible.  You may add other material on the covers in addition.
1370Copying with changes limited to the covers, as long as they preserve
1371the title of the Document and satisfy these conditions, can be treated
1372as verbatim copying in other respects.
1373
1374If the required texts for either cover are too voluminous to fit
1375legibly, you should put the first ones listed (as many as fit
1376reasonably) on the actual cover, and continue the rest onto adjacent
1377pages.
1378
1379If you publish or distribute Opaque copies of the Document numbering
1380more than 100, you must either include a machine-readable Transparent
1381copy along with each Opaque copy, or state in or with each Opaque copy
1382a computer-network location from which the general network-using
1383public has access to download using public-standard network protocols
1384a complete Transparent copy of the Document, free of added material.
1385If you use the latter option, you must take reasonably prudent steps,
1386when you begin distribution of Opaque copies in quantity, to ensure
1387that this Transparent copy will remain thus accessible at the stated
1388location until at least one year after the last time you distribute an
1389Opaque copy (directly or through your agents or retailers) of that
1390edition to the public.
1391
1392It is requested, but not required, that you contact the authors of the
1393Document well before redistributing any large number of copies, to give
1394them a chance to provide you with an updated version of the Document.
1395
1396
13974. MODIFICATIONS
1398
1399You may copy and distribute a Modified Version of the Document under
1400the conditions of sections 2 and 3 above, provided that you release
1401the Modified Version under precisely this License, with the Modified
1402Version filling the role of the Document, thus licensing distribution
1403and modification of the Modified Version to whoever possesses a copy
1404of it.  In addition, you must do these things in the Modified Version:
1405
1406A. Use in the Title Page (and on the covers, if any) a title distinct
1407   from that of the Document, and from those of previous versions
1408   (which should, if there were any, be listed in the History section
1409   of the Document).  You may use the same title as a previous version
1410   if the original publisher of that version gives permission.
1411B. List on the Title Page, as authors, one or more persons or entities
1412   responsible for authorship of the modifications in the Modified
1413   Version, together with at least five of the principal authors of the
1414   Document (all of its principal authors, if it has fewer than five),
1415   unless they release you from this requirement.
1416C. State on the Title page the name of the publisher of the
1417   Modified Version, as the publisher.
1418D. Preserve all the copyright notices of the Document.
1419E. Add an appropriate copyright notice for your modifications
1420   adjacent to the other copyright notices.
1421F. Include, immediately after the copyright notices, a license notice
1422   giving the public permission to use the Modified Version under the
1423   terms of this License, in the form shown in the Addendum below.
1424G. Preserve in that license notice the full lists of Invariant Sections
1425   and required Cover Texts given in the Document's license notice.
1426H. Include an unaltered copy of this License.
1427I. Preserve the section Entitled "History", Preserve its Title, and add
1428   to it an item stating at least the title, year, new authors, and
1429   publisher of the Modified Version as given on the Title Page.  If
1430   there is no section Entitled "History" in the Document, create one
1431   stating the title, year, authors, and publisher of the Document as
1432   given on its Title Page, then add an item describing the Modified
1433   Version as stated in the previous sentence.
1434J. Preserve the network location, if any, given in the Document for
1435   public access to a Transparent copy of the Document, and likewise
1436   the network locations given in the Document for previous versions
1437   it was based on.  These may be placed in the "History" section.
1438   You may omit a network location for a work that was published at
1439   least four years before the Document itself, or if the original
1440   publisher of the version it refers to gives permission.
1441K. For any section Entitled "Acknowledgements" or "Dedications",
1442   Preserve the Title of the section, and preserve in the section all
1443   the substance and tone of each of the contributor acknowledgements
1444   and/or dedications given therein.
1445L. Preserve all the Invariant Sections of the Document,
1446   unaltered in their text and in their titles.  Section numbers
1447   or the equivalent are not considered part of the section titles.
1448M. Delete any section Entitled "Endorsements".  Such a section
1449   may not be included in the Modified Version.
1450N. Do not retitle any existing section to be Entitled "Endorsements"
1451   or to conflict in title with any Invariant Section.
1452O. Preserve any Warranty Disclaimers.
1453
1454If the Modified Version includes new front-matter sections or
1455appendices that qualify as Secondary Sections and contain no material
1456copied from the Document, you may at your option designate some or all
1457of these sections as invariant.  To do this, add their titles to the
1458list of Invariant Sections in the Modified Version's license notice.
1459These titles must be distinct from any other section titles.
1460
1461You may add a section Entitled "Endorsements", provided it contains
1462nothing but endorsements of your Modified Version by various
1463parties--for example, statements of peer review or that the text has
1464been approved by an organization as the authoritative definition of a
1465standard.
1466
1467You may add a passage of up to five words as a Front-Cover Text, and a
1468passage of up to 25 words as a Back-Cover Text, to the end of the list
1469of Cover Texts in the Modified Version.  Only one passage of
1470Front-Cover Text and one of Back-Cover Text may be added by (or
1471through arrangements made by) any one entity.  If the Document already
1472includes a cover text for the same cover, previously added by you or
1473by arrangement made by the same entity you are acting on behalf of,
1474you may not add another; but you may replace the old one, on explicit
1475permission from the previous publisher that added the old one.
1476
1477The author(s) and publisher(s) of the Document do not by this License
1478give permission to use their names for publicity for or to assert or
1479imply endorsement of any Modified Version.
1480
1481
14825. COMBINING DOCUMENTS
1483
1484You may combine the Document with other documents released under this
1485License, under the terms defined in section 4 above for modified
1486versions, provided that you include in the combination all of the
1487Invariant Sections of all of the original documents, unmodified, and
1488list them all as Invariant Sections of your combined work in its
1489license notice, and that you preserve all their Warranty Disclaimers.
1490
1491The combined work need only contain one copy of this License, and
1492multiple identical Invariant Sections may be replaced with a single
1493copy.  If there are multiple Invariant Sections with the same name but
1494different contents, make the title of each such section unique by
1495adding at the end of it, in parentheses, the name of the original
1496author or publisher of that section if known, or else a unique number.
1497Make the same adjustment to the section titles in the list of
1498Invariant Sections in the license notice of the combined work.
1499
1500In the combination, you must combine any sections Entitled "History"
1501in the various original documents, forming one section Entitled
1502"History"; likewise combine any sections Entitled "Acknowledgements",
1503and any sections Entitled "Dedications".  You must delete all sections
1504Entitled "Endorsements".
1505

1509You may make a collection consisting of the Document and other documents
1510released under this License, and replace the individual copies of this
1511License in the various documents with a single copy that is included in
1512the collection, provided that you follow the rules of this License for
1513verbatim copying of each of the documents in all other respects.
1514
1515You may extract a single document from such a collection, and distribute
1516it individually under this License, provided you insert a copy of this
1517License into the extracted document, and follow this License in all
1518other respects regarding verbatim copying of that document.
1519
1520
15217. AGGREGATION WITH INDEPENDENT WORKS
1522
1523A compilation of the Document or its derivatives with other separate
1524and independent documents or works, in or on a volume of a storage or
1525distribution medium, is called an "aggregate" if the copyright
1526resulting from the compilation is not used to limit the legal rights
1527of the compilation's users beyond what the individual works permit.
1528When the Document is included in an aggregate, this License does not
1529apply to the other works in the aggregate which are not themselves
1530derivative works of the Document.
1531
1532If the Cover Text requirement of section 3 is applicable to these
1533copies of the Document, then if the Document is less than one half of
1534the entire aggregate, the Document's Cover Texts may be placed on
1535covers that bracket the Document within the aggregate, or the
1536electronic equivalent of covers if the Document is in electronic form.
1537Otherwise they must appear on printed covers that bracket the whole
1538aggregate.
1539
1540
15418. TRANSLATION
1542
1543Translation is considered a kind of modification, so you may
1544distribute translations of the Document under the terms of section 4.
1545Replacing Invariant Sections with translations requires special
1546permission from their copyright holders, but you may include
1547translations of some or all Invariant Sections in addition to the
1548original versions of these Invariant Sections.  You may include a
1549translation of this License, and all the license notices in the
1550Document, and any Warranty Disclaimers, provided that you also include
1551the original English version of this License and the original versions
1552of those notices and disclaimers.  In case of a disagreement between
1553the translation and the original version of this License or a notice
1554or disclaimer, the original version will prevail.
1555
1556If a section in the Document is Entitled "Acknowledgements",
1557"Dedications", or "History", the requirement (section 4) to Preserve
1558its Title (section 1) will typically require changing the actual
1559title.
1560
1561
15629. TERMINATION
1563
1564You may not copy, modify, sublicense, or distribute the Document except
1565as expressly provided for under this License.  Any other attempt to
1566copy, modify, sublicense or distribute the Document is void, and will
1567automatically terminate your rights under this License.  However,
1568parties who have received copies, or rights, from you under this
1569License will not have their licenses terminated so long as such
1570parties remain in full compliance.
1571
1572
157310. FUTURE REVISIONS OF THIS LICENSE
1574
1575The Free Software Foundation may publish new, revised versions
1576of the GNU Free Documentation License from time to time.  Such new
1577versions will be similar in spirit to the present version, but may
1578differ in detail to address new problems or concerns.  See
1579https://www.gnu.org/copyleft/.
1580
1581Each version of the License is given a distinguishing version number.
1582If the Document specifies that a particular numbered version of this
1583License "or any later version" applies to it, you have the option of
1584following the terms and conditions either of that specified version or
1585of any later version that has been published (not as a draft) by the
1586Free Software Foundation.  If the Document does not specify a version
1587number of this License, you may choose any version ever published (not
1588as a draft) by the Free Software Foundation.

1591ADDENDUM: How to use this License for your documents
1592
1593To use this License in a document you have written, include a copy of
1594the License in the document and put the following copyright and
1595license notices just after the title page:
1596
1597    Copyright (c)  YEAR  YOUR NAME.
1598    Permission is granted to copy, distribute and/or modify this document
1599    under the terms of the GNU Free Documentation License, Version 1.2
1600    or any later version published by the Free Software Foundation;
1601    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
1602    A copy of the license is included in the section entitled "GNU
1603    Free Documentation License".
1604
1605If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
1606replace the "with...Texts." line with this:
1607
1608    with the Invariant Sections being LIST THEIR TITLES, with the
1609    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
1610
1611If you have Invariant Sections without Cover Texts, or some other
1612combination of the three, merge those two alternatives to suit the
1613situation.
1614
1615If your document contains nontrivial examples of program code, we
1616recommend releasing these examples in parallel under your choice of
1617free software license, such as the GNU General Public License,
1618to permit their use in free software.
1619
1620The End.
