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.

347
3485. The Speakup Sys System
349
350The Speakup screen reader also creates a speakup subdirectory as a part
351of the sys system.
352
353As a convenience, run as root
354
355ln -s /sys/accessibility/speakup /speakup
356
357to directly access speakup parameters from /speakup.
358You can see these entries by typing the command:
359
360ls -1 /speakup/*
361
362If you issue the above ls command, you will get back something like
363this:
364
365/speakup/attrib_bleep
366/speakup/bell_pos
367/speakup/bleep_time
368/speakup/bleeps
369/speakup/cursor_time

414vol
415
416Notice the two subdirectories of /speakup: /speakup/i18n and
417/speakup/soft.
418The i18n subdirectory is described in a later section.
419The files under /speakup/soft represent settings that are specific to the
420driver for the software synthesizer. If you use the LiteTalk, your
421synthesizer-specific settings would be found in /speakup/ltlk. In other words,
422a subdirectory named /speakup/KWD is created to hold parameters specific
423to the device whose keyword is KWD.
424These parameters include volume, rate, pitch, and others.
425
426In addition to using the Speakup hot keys to change such things as
427volume, pitch, and rate, you can also echo values to the appropriate
428entry in the /speakup directory. This is very useful, since it
429lets you control Speakup parameters from within a script. How you
430would write such scripts is somewhat beyond the scope of this manual,
431but I will include a couple of simple examples here to give you a
432general idea of what such scripts can do.
433
434Suppose for example, that you wanted to control both the punctuation
435level and the reading punctuation level at the same time. For
436simplicity, we'll call them punc0, punc1, punc2, and punc3. The scripts
437might look something like this:
438
439#!/bin/bash
440# punc0
441# set punc and reading punc levels to 0
442echo 0 >/speakup/punc_level
443echo 0 >/speakup/reading_punc
444echo Punctuation level set to 0.
445
446#!/bin/bash
447# punc1
448# set punc and reading punc levels to 1
449echo 1 >/speakup/punc_level
450echo 1 >/speakup/reading_punc
451echo Punctuation level set to 1.
452
453#!/bin/bash
454# punc2
455# set punc and reading punc levels to 2
456echo 2 >/speakup/punc_level
457echo 2 >/speakup/reading_punc
458echo Punctuation level set to 2.
459
460#!/bin/bash
461# punc3
462# set punc and reading punc levels to 3
463echo 3 >/speakup/punc_level
464echo 3 >/speakup/reading_punc
465echo Punctuation level set to 3.
466
467If you were to store these four small scripts in a directory in your
468path, perhaps /usr/local/bin, and set the permissions to 755 with the
469chmod command, then you could change the default reading punc and
470punctuation levels at the same time by issuing just one command. For
471example, if you were to execute the punc3 command at your shell prompt,
472then the reading punc and punc level would both get set to 3.
473
474I should note that the above scripts were written to work with bash, but
475regardless of which shell you use, you should be able to do something
476similar.
477
478The Speakup sys system also has another interesting use. You can echo
479Speakup parameters into the sys system in a script during system
480startup, and speakup will return to your preferred parameters every time
481the system is rebooted.
482
483Most of the Speakup sys parameters can be manipulated by a regular user
484on the system. However, there are a few parameters that are dangerous
485enough that they should only be manipulated by the root user on your
486system. There are even some parameters that are read only, and cannot
487be written to at all. For example, the version entry in the Speakup
488sys system is read only. This is because there is no reason for a user
489to tamper with the version number which is reported by Speakup. Doing
490an ls -l on /speakup/version will return this:
491
492-r--r--r-- 1 root root 0 Mar 21 13:46 /speakup/version
493
494As you can see, the version entry in the Speakup sys system is read
495only, is owned by root, and belongs to the root group. Doing a cat of
496/speakup/version will display the Speakup version number, like
497this:
498
499cat /speakup/version
500Speakup v-2.00 CVS: Thu Oct 21 10:38:21 EDT 2004
501synth dtlk version 1.1
502
503The display shows the Speakup version number, along with the version
504number of the driver for the current synthesizer.
505
506Looking at entries in the Speakup sys system can be useful in many
507ways. For example, you might wish to know what level your volume is set
508at. You could type:
509
510cat /speakup/KWD/vol
511# Replace KWD with the keyword for your synthesizer, E.G., ltlk for LiteTalk.
5125
513
514The number five which comes back is the level at which the synthesizer
515volume is set at.
516
517All the entries in the Speakup sys system are readable, some are
518writable by root only, and some are writable by everyone. Unless you
519know what you are doing, you should probably leave the ones that are
520writable by root only alone. Most of the names are self explanatory.
521Vol for controlling volume, pitch for pitch, rate for controlling speaking
522rate, etc. If you find one you aren't sure about, you can post a query
523on the Speakup list.
524
5256. Changing Synthesizers
526
527It is possible to change to a different synthesizer while speakup is
528running. In other words, it is not necessary to reboot the system
529in order to use a different synthesizer. You can simply echo the
530synthesizer keyword to the /speakup/synth sys entry.
531Depending on your situation, you may wish to echo none to the synth
532sys entry, to disable speech while one synthesizer is disconnected and
533a second one is connected in its place. Then echo the keyword for the
534new synthesizer into the synth sys entry in order to start speech
535with the newly connected synthesizer. See the list of synthesizer
536keywords in section 1 to find the keyword which matches your synth.
537
5387. Loading modules
539
540As mentioned earlier, Speakup can either be completely compiled into the
541kernel, with the exception of the help module, or it can be compiled as
542a series of modules. When compiled as modules, Speakup will only be
543able to speak some of the bootup messages if your system administrator
544has configured the system to load the modules at boo time. The modules
545can be loaded after the file systems have been checked and mounted, or
546from an initrd. There is a third possibility. Speakup can be compiled
547with some components built into the kernel, and others as modules. As
548we'll see in the next section, this is particularly useful when you are
549working with software synthesizers.
550
551If Speakup is completely compiled as modules, then you must use the
552modprobe command to load Speakup. You do this by loading the module for
553the synthesizer driver you wish to use. The driver modules are all
554named speakup_<keyword>, where <keyword> is the keyword for the
555synthesizer you want. So, in order to load the driver for the DecTalk
556Express, you would type the following command:
557
558modprobe speakup_dectlk
559
560Issuing this command would load the DecTalk Express driver and all other
561related Speakup modules necessary to get Speakup up and running.
562
563To completely unload Speakup, again presuming that it is entirely built
564as modules, you would give the command:
565
566modprobe -r speakup_dectlk
567
568The above command assumes you were running a DecTalk Express. If you
569were using a different synth, then you would substitute its keyword in
570place of dectlk.
571
572If you have multiple drivers loaded, you need to unload all of them, in
573order to completely unload Speakup.
574For example, if you have loaded both the dectlk and ltlk drivers, use the
575command:
576modprobe -r speakup_dectlk speakup_ltlk
577
578You cannot unload the driver for software synthesizers when a user-space
579daemon is using /dev/softsynth. First, kill the daemon. Next, remove
580the driver with the command:
581modprobe -r speakup_soft
582
583Now, suppose we have a situation where the main Speakup component
584is built into the kernel, and some or all of the drivers are built as
585modules. Since the main part of Speakup is compiled into the kernel, a
586partial Speakup sys system has been created which we can take advantage
587of by simply echoing the synthesizer keyword into the
588/speakup/synth sys entry. This will cause the kernel to
589automatically load the appropriate driver module, and start Speakup
590talking. To switch to another synth, just echo a new keyword to the
591synth sys entry. For example, to load the DoubleTalk LT driver,
592you would type:
593
594echo ltlk >/speakup/synth
595
596You can use the modprobe -r command to unload driver modules, regardless
597of whether the main part of Speakup has been built into the kernel or
598not.
599
6008. Using Software Synthesizers
601
602Using a software synthesizer requires that some other software be
603installed and running on your system. For this reason, software
604synthesizers are not available for use at bootup, or during a system
605installation process.
606There are two freely-available solutions for software speech: Espeakup and
607Speech Dispatcher.
608These are described in subsections 8.1 and 8.2, respectively.
609
610During the rest of this section, we assume that speakup_soft is either
611built in to your kernel, or loaded as a module.
612
613If your system does not have udev installed , before you can use a
614software synthesizer, you must have created the /dev/softsynth device.
615If you have not already done so, issue the following commands as root:
616
617cd /dev
618mknod softsynth c 10 26
619
620While we are at it, we might just as well create the /dev/synth device,
621which can be used to let user space programs send information to your
622synthesizer. To create /dev/synth, change to the /dev directory, and
623issue the following command as root:
624
625mknod synth c 10 25
626
627of both.
628
6298.1. Espeakup
630
631Espeakup is a connector between Speakup and the eSpeak software synthesizer.
632Espeakup may already be available as a package for your distribution
633of Linux. If it is not packaged, you need to install it manually.
634You can find it in the contrib/ subdirectory of the Speakup sources.
635The filename is espeakup-$VERSION.tar.bz2, where $VERSION
636depends on the current release of Espeakup. The Speakup 3.1.2 source
637ships with version 0.71 of Espeakup.
638The README file included with the Espeakup sources describes the process
639of manual installation.
640
641Assuming that Espeakup is installed, either by the user or by the distributor,
642follow these steps to use it.
643
644Tell Speakup to use the "soft driver:
645echo soft > /speakup/synth
646
647Finally, start the espeakup program. There are two ways to do it.
648Both require root privileges.
649
650If Espeakup was installed as a package for your Linux distribution,
651you probably have a distribution-specific script that controls the operation
652of the daemon. Look for a file named espeakup under /etc/init.d or
653/etc/rc.d. Execute the following command with root privileges:
654/etc/init.d/espeakup start
655Replace init.d with rc.d, if your distribution uses scripts located under
656/etc/rc.d.
657Your distribution will also have a procedure for starting daemons at
658boot-time, so it is possible to have software speech as soon as user-space
659daemons are started by the bootup scripts.
660These procedures are not described in this document.
661
662If you built Espeakup manually, the "make install" step placed the binary
663under /usr/bin.
664Run the following command as root:
665/usr/bin/espeakup
666Espeakup should start speaking.
667
6688.2. Speech Dispatcher
669
670For this option, you must have a package called
671Speech Dispatcher running on your system, and it must be configured to
672work with one of its supported software synthesizers.
673
674Two open source synthesizers you might use are Flite and Festival. You
675might also choose to purchase the Software DecTalk from Fonix Sales Inc.
676If you run a google search for Fonix, you'll find their web site.
677
678You can obtain a copy of Speech Dispatcher from free(b)soft at
679http://www.freebsoft.org/. Follow the installation instructions that
680come with Speech Dispatcher in order to install and configure Speech
681Dispatcher. You can check out the web site for your Linux distribution
682in order to get a copy of either Flite or Festival. Your Linux
683distribution may also have a precompiled Speech Dispatcher package.
684
685Once you've installed, configured, and tested Speech Dispatcher with your
686chosen software synthesizer, you still need one more piece of software
687in order to make things work. You need a package called speechd-up.
688You get it from the free(b)soft web site mentioned above. After you've
689compiled and installed speechd-up, you are almost ready to begin using
690your software synthesizer.
691
692Now you can begin using your software synthesizer. In order to do so,
693echo the soft keyword to the synth sys entry like this:
694
695echo soft >/speakup/synth
696
697Next run the speechd_up command like this:
698
699speechd_up &
700
701Your synth should now start talking, and you should be able to adjust
702the pitch, rate, etc.
703
7049. Using The DecTalk PC Card
705
706The DecTalk PC card is an ISA card that is inserted into one of the ISA
707slots in your computer. It requires that the DecTalk PC software be
708installed on your computer, and that the software be loaded onto the
709Dectalk PC card before it can be used.
710
711You can get the dec_pc.tgz file from the linux-speakup.org site. The
712dec_pc.tgz file is in the ~ftp/pub/linux/speakup directory.
713
714After you have downloaded the dec_pc.tgz file, untar it in your home
715directory, and read the Readme file in the newly created dec_pc
716directory.
717
718The easiest way to get the software working is to copy the entire dec_pc
719directory into /user/local/lib. To do this, su to root in your home
720directory, and issue the command:
721
722cp dec_pc /usr/local/lib
723
724You will need to copy the dtload command from the dec_pc directory to a
725directory in your path. Either /usr/bin or /usr/local/bin is a good
726choice.
727
728You can now run the dtload command in order to load the DecTalk PC
729software onto the card. After you have done this, echo the decpc
730keyword to the synth entry in the sys system like this:
731
732echo decpc >/speakup/synth
733
734Your DecTalk PC should start talking, and then you can adjust the pitch,
735rate, volume, voice, etc. The voice entry in the Speakup sys system
736will accept a number from 0 through 7 for the DecTalk PC synthesizer,
737which will give you access to some of the DecTalk voices.
738
73910. Using Cursor Tracking
740
741In Speakup version 2.0 and later, cursor tracking is turned on by
742default. This means that when you are using an editor, Speakup will
743automatically speak characters as you move left and right with the
744cursor keys, and lines as you move up and down with the cursor keys.
745This is the traditional sort of cursor tracking.
746Recent versions of Speakup provide two additional ways to control the
747text that is spoken when the cursor is moved:
748"highlight tracking" and "read window."
749They are described later in this section.
750Sometimes, these modes get in your way, so you can disable cursor tracking
751altogether.
752
753You may select among the various forms of cursor tracking using the keypad
754asterisk key.
755Each time you press this key, a new mode is selected, and Speakup speaks
756the name of the new mode. The names for the four possible states of cursor
757tracking are: "cursoring on", "highlight tracking", "read window",
758and "cursoring off." The keypad asterisk key moves through the list of
759modes in a circular fashion.
760
761If highlight tracking is enabled, Speakup tracks highlighted text,
762rather than the cursor itself. When you move the cursor with the arrow keys,
763Speakup speaks the currently highlighted information.
764This is useful when moving through various menus and dialog boxes.
765If cursor tracking isn't helping you while navigating a menu,
766try highlight tracking.
767
768With the "read window" variety of cursor tracking, you can limit the text
769that Speakup speaks by specifying a window of interest on the screen.
770See section 15 for a description of the process of defining windows.
771When you move the cursor via the arrow keys, Speakup only speaks
772the contents of the window. This is especially helpful when you are hearing
773superfluous speech. Consider the following example.
774
775Suppose that you are at a shell prompt. You use bash, and you want to
776explore your command history using the up and down arrow keys. If you
777have enabled cursor tracking, you will hear two pieces of information.
778Speakup speaks both your shell prompt and the current entry from the
779command history. You may not want to hear the prompt repeated
780each time you move, so you can silence it by specifying a window. Find
781the last line of text on the screen. Clear the current window by pressing
782the key combination speakup f3. Use the review cursor to find the first
783character that follows your shell prompt. Press speakup + f2 twice, to
784define a one-line window. The boundaries of the window are the
785character following the shell prompt and the end of the line. Now, cycle
786through the cursor tracking modes using keypad asterisk, until Speakup
787says "read window." Move through your history using your arrow keys.
788You will notice that Speakup no longer speaks the redundant prompt.
789
790Some folks like to turn cursor tracking off while they are using the
791lynx web browser. You definitely want to turn cursor tracking off when
792you are using the alsamixer application. Otherwise, you won't be able
793to hear your mixer settings while you are using the arrow keys.
794
79511. Cut and Paste
796
797One of Speakup's more useful features is the ability to cut and paste
798text on the screen. This means that you can capture information from a
799program, and paste that captured text into a different place in the
800program, or into an entirely different program, which may even be
801running on a different console.
802
803For example, in this manual, we have made references to several web
804sites. It would be nice if you could cut and paste these urls into your
805web browser. Speakup does this quite nicely. Suppose you wanted to
806past the following url into your browser:
807
808http://linux-speakup.org/
809
810Use the speakup review keys to position the reading cursor on the first
811character of the above url. When the reading cursor is in position,
812press the keypad slash key once. Speakup will say, "mark". Next,
813position the reading cursor on the rightmost character of the above
814url. Press the keypad slash key once again to actually cut the text
815from the screen. Speakup will say, "cut". Although we call this
816cutting, Speakup does not actually delete the cut text from the screen.
817It makes a copy of the text in a special buffer for later pasting.
818
819Now that you have the url cut from the screen, you can paste it into
820your browser, or even paste the url on a command line as an argument to
821your browser.
822
823Suppose you want to start lynx and go to the Speakup site.
824
825You can switch to a different console with the alt left and right
826arrows, or you can switch to a specific console by typing alt and a
827function key. These are not Speakup commands, just standard Linux
828console capabilities.
829
830Once you've changed to an appropriate console, and are at a shell prompt,
831type the word lynx, followed by a space. Now press and hold the speakup
832key, while you type the keypad slash character. The url will be pasted
833onto the command line, just as though you had typed it in. Press the
834enter key to execute the command.
835
836The paste buffer will continue to hold the cut information, until a new
837mark and cut operation is carried out. This means you can paste the cut
838information as many times as you like before doing another cut
839operation.
840
841You are not limited to cutting and pasting only one line on the screen.
842You can also cut and paste rectangular regions of the screen. Just
843position the reading cursor at the top left corner of the text to be
844cut, mark it with the keypad slash key, then position the reading cursor
845at the bottom right corner of the region to be cut, and cut it with the
846keypad slash key.
847
84812. Changing the Pronunciation of Characters
849
850Through the /speakup/i18n/characters sys entry, Speakup gives you the
851ability to change how Speakup pronounces a given character. You could,
852for example, change how some punctuation characters are spoken. You can
853even change how Speakup will pronounce certain letters.
854
855You may, for example, wish to change how Speakup pronounces the z
856character. The author of Speakup, Kirk Reiser, is Canadian, and thus
857believes that the z should be pronounced zed. If you are an American,
858you might wish to use the zee pronunciation instead of zed. You can
859change the pronunciation of both the upper and lower case z with the
860following two commands:
861
862echo 90 zee >/speakup/characters
863echo 122 zee >/speakup/characters
864
865Let's examine the parts of the two previous commands. They are issued
866at the shell prompt, and could be placed in a startup script.
867
868The word echo tells the shell that you want to have it display the
869string of characters that follow the word echo. If you were to just
870type:
871
872echo hello.
873
874You would get the word hello printed on your screen as soon as you
875pressed the enter key. In this case, we are echoing strings that we
876want to be redirected into the sys system.
877
878The numbers 90 and 122 in the above echo commands are the ascii numeric
879values for the upper and lower case z, the characters we wish to change.
880
881The string zee is the pronunciation that we want Speakup to use for the
882upper and lower case z.
883
884The > symbol redirects the output of the echo command to a file, just
885like in DOS, or at the Windows command prompt.
886
887And finally, /speakup/i18n/characters is the file entry in the sys system
888where we want the output to be directed. Speakup looks at the numeric
889value of the character we want to change, and inserts the pronunciation
890string into an internal table.
891
892You can look at the whole table with the following command:
893
894cat /speakup/i18n/characters
895
896Speakup will then print out the entire character pronunciation table. I
897won't display it here, but leave you to look at it at your convenience.
898
89913. Mapping Keys
900
901Speakup has the capability of allowing you to assign or "map" keys to
902internal Speakup commands. This section necessarily assumes you have a
903Linux kernel source tree installed, and that it has been patched and
904configured with Speakup. How you do this is beyond the scope of this
905manual. For this information, visit the Speakup web site at
906http://linux-speakup.org/. The reason you'll need the kernel source
907tree patched with Speakup is that the genmap utility you'll need for
908processing keymaps is in the
909/usr/src/linux-<version_number>/drivers/char/speakup directory. The
910<version_number> in the above directory path is the version number of
911the Linux source tree you are working with.
912
913So ok, you've gone off and gotten your kernel source tree, and patched
914and configured it. Now you can start manipulating keymaps.
915
916You can either use the
917/usr/src/linux-<version_number>/drivers/char/speakup/speakupmap.map file
918included with the Speakup source, or you can cut and paste the copy in
919section 4 into a separate file. If you use the one in the Speakup
920source tree, make sure you make a backup of it before you start making
921changes. You have been warned!
922
923Suppose that you want to swap the key assignments for the Speakup
924say_last_char and the Speakup say_first_char commands. The
925speakupmap.map lists the key mappings for these two commands as follows:
926
927spk key_pageup = say_first_char
928spk key_pagedown = say_last_char
929
930You can edit your copy of the speakupmap.map file and swap the command
931names on the right side of the = (equals) sign. You did make a backup,
932right? The new keymap lines would look like this:
933
934spk key_pageup = say_last_char
935spk key_pagedown = say_first_char
936
937After you edit your copy of the speakupmap.map file, save it under a new
938file name, perhaps newmap.map. Then exit your editor and return to the
939shell prompt.
940
941You are now ready to load your keymap with your swapped key assignments.
942 Assuming that you saved your new keymap as the file newmap.map, you
943would load your keymap into the sys system like this:
944
945/usr/src/linux-<version_number>/drivers/char/speakup/genmap newmap.map
946>/speakup/keymap
947
948Remember to substitute your kernel version number for the
949<version_number> in the above command. Also note that although the
950above command wrapped onto two lines in this document, you should type
951it all on one line.
952
953Your say first and say last characters should now be swapped. Pressing
954speakup pagedown should read you the first non-whitespace character on
955the line your reading cursor is in, and pressing speakup pageup should
956read you the last character on the line your reading cursor is in.
957
958You should note that these new mappings will only stay in effect until
959you reboot, or until you load another keymap.
960
961One final warning. If you try to load a partial map, you will quickly
962find that all the mappings you didn't include in your file got deleted
963from the working map. Be extremely careful, and always make a backup!
964You have been warned!
965
96614. Internationalizing Speakup
967
968Speakup indicates various conditions to the user by speaking messages.
969For instance, when you move to the left edge of the screen with the
970review keys, Speakup says, "left."
971Prior to version 3.1.0 of Speakup, all of these messages were in English,
972and they could not be changed. If you used a non-English synthesizer,
973you still heard English messages, such as "left" and "cursoring on."
974In version 3.1.0 or higher, one may load translations for the various
975messages via the /sys filesystem.
976
977The directory /speakup/i18n contains several collections of messages.
978Each group of messages is stored in its own file.
979The following section lists all of these files, along with a brief description
980of each.
981
98214.1. Files Under the i18n Subdirectory
983
984* announcements:
985This file contains various general announcements, most of which cannot
986be categorized. You will find messages such as "You killed Speakup",
987"I'm alive", "leaving help", "parked", "unparked", and others.
988You will also find the names of the screen edges and cursor tracking modes
989here.
990
991* characters:
992See section 12 for a description of this file.
993
994* chartab:
995See section 12. Unlike the rest of the files in the i18n subdirectory,
996this one does not contain messages to be spoken.
997
998* colors:
999When you use the "say attributes" function, Speakup says the name of the
1000foreground and background colors. These names come from the i18n/colors
1001file.
1002
1003* ctl_keys:
1004Here, you will find names of control keys. These are used with Speakup's
1005say_control feature.
1006
1007* formatted:
1008This group of messages contains embedded formatting codes, to specify
1009the type and width of displayed data. If you change these, you must
1010preserve all of the formatting codes, and they must appear in the order
1011used by the default messages.
1012
1013* function_names:
1014Here, you will find a list of names for Speakup functions. These are used
1015by the help system. For example, suppose that you have activated help mode,
1016and you pressed keypad 3. Speakup says:
1017"keypad 3 is character, say next."
1018The message "character, say next" names a Speakup function, and it
1019comes from this function_names file.
1020
1021* key_names:
1022Again, key_names is used by Speakup's help system. In the previous
1023example, Speakup said that you pressed "keypad 3."
1024This name came from the key_names file.
1025
1026* states:
1027This file contains names for key states.
1028Again, these are part of the help system. For instance, if you had pressed
1029speakup + keypad 3, you would hear:
1030"speakup keypad 3 is go to bottom edge."
1031The speakup key is depressed, so the name of the key state is speakup.
1032This part of the message comes from the states collection.
1033
103414.2. Loading Your Own Messages
1035
1036The files under the i18n subdirectory all follow the same format.
1037They consist of lines, with one message per line.
1038Each message is represented by a number, followed by the text of the message.
1039The number is the position of the message in the given collection.
1040For example, if you view the file /speakup/i18n/colors, you will see the
1041following list:
1042
10430 black
10441 blue
10452 green
10463 cyan
10474 red
10485 magenta
10496 yellow
10507 white
10518 grey
1052
1053You can change one message, or you can change a whole group.
1054To load a whole collection of messages from a new source, simply use
1055the cp command:
1056cp ~/my_colors /speakup/i18n/colors
1057You can change an individual message with the echo command,
1058as shown in the following example.
1059
1060The Spanish name for the color blue is azul.
1061Looking at the colors file, we see that the name "blue" is at position 1
1062within the colors group. Let's change blue to azul:
1063echo '1 azul' > /speakup/i18n/colors
1064The next time that Speakup says message 1 from the colors group, it will
1065say "azul", rather than "blue."
1066
1067In the future, translations into various languages will be made available,
1068and most users will just load the files necessary for their language.
1069
107014.3. No Support for Non-Western-European Languages
1071
1072As of the current release, Speakup only supports Western European languages.
1073Support for the extended characters used by languages outside of the Western
1074European family of languages is a work in progress.
1075
107615. Using Speakup's Windowing Capability
1077
1078Speakup has the capability of defining and manipulating windows on the
1079screen. Speakup uses the term "Window", to mean a user defined area of
1080the screen. The key strokes for defining and manipulating Speakup
1081windows are as follows:
1082
1083speakup + f2 -- Set the bounds of the window.
1084Speakup + f3 -- clear the current window definition.
1085speakup + f4 -- Toggle window silence on and off.
1086speakup + keypad plus -- Say the currently defined window.
1087
1088These capabilities are useful for tracking a certain part of the screen
1089without rereading the whole screen, or for silencing a part of the
1090screen that is constantly changing, such as a clock or status line.
1091
1092There is no way to save these window settings, and you can only have one
1093window defined for each virtual console. There is also no way to have
25985edc 1094windows automatically defined for specific applications.
c6e3fd22
WH
1095
1096In order to define a window, use the review keys to move your reading
1097cursor to the beginning of the area you want to define. Then press
1098speakup + f2. Speakup will tell you that the window starts at the
1099indicated row and column position. Then move the reading cursor to the
1100end of the area to be defined as a window, and press speakup + f2 again.
1101 If there is more than one line in the window, Speakup will tell you
1102that the window ends at the indicated row and column position. If there
1103is only one line in the window, then Speakup will tell you that the
1104window is the specified line on the screen. If you are only defining a
1105one line window, you can just press speakup + f2 twice after placing the
1106reading cursor on the line you want to define as a window. It is not
1107necessary to position the reading cursor at the end of the line in order
1108to define the whole line as a window.
1109
111016. Tools for Controlling Speakup
1111
1112The speakup distribution includes extra tools (in the tools directory)
1113which were written to make speakup easier to use. This section will
1114briefly describe the use of these tools.
1115
111616.1. Speakupconf
1117
1118speakupconf began life as a contribution from Steve Holmes, a member of
1119the speakup community. We would like to thank him for his work on the
1120early versions of this project.
1121
1122This script may be installed as part of your linux distribution, but if
1123it isn't, the recommended places to put it are /usr/local/bin or
1124/usr/bin. This script can be run by any user, so it does not require
1125root privileges.
1126
1127Speakupconf allows you to save and load your Speakup settings. It works
1128by reading and writing the /sys files described above.
1129
1130The directory that speakupconf uses to store your settings depends on
1131whether it is run from the root account. If you execute speakupconf as
1132root, it uses the directory /etc/speakup. Otherwise, it uses the directory
1133~/.speakup, where ~ is your home directory.
1134Anyone who needs to use Speakup from your console can load his own custom
1135settings with this script.
1136
1137speakupconf takes one required argument: load or save.
1138Use the command
1139speakupconf save
1140to save your Speakup settings, and
1141speakupconf load
1142to load them into Speakup.
1143A second argument may be specified to use an alternate directory to
1144load or save the speakup parameters.
1145
114616.2. Talkwith
1147
1148Charles Hallenbeck, another member of the speakup community, wrote the
1149initial versions of this script, and we would also like to thank him for
1150his work on it.
1151
1152This script needs root privileges to run, so if it is not installed as
1153part of your linux distribution, the recommended places to install it
1154are /usr/local/sbin or /usr/sbin.
1155
1156Talkwith allows you to switch synthesizers on the fly. It takes a synthesizer
1157name as an argument. For instance,
1158talkwith dectlk
1159causes Speakup to use the DecTalk Express. If you wish to switch to a
1160software synthesizer, you must also indicate which daemon you wish to
1161use. There are two possible choices:
1162spd and espeakup. spd is an abbreviation for speechd-up.
1163If you wish to use espeakup for software synthesis, give the command
1164talkwith soft espeakup
1165To use speechd-up, type:
1166talkwith soft spd
1167Any arguments that follow the name of the daemon are passed to the daemon
1168when it is invoked. For instance:
1169talkwith espeakup --default-voice=fr
1170causes espeakup to use the French voice.
1171Note that talkwith must always be executed with root privileges.
1172
1173Talkwith does not attempt to load your settings after the new
1174synthesizer is activated. You can use speakupconf to load your settings
1175if desired.

1183 Everyone is permitted to copy and distribute verbatim copies
1184 of this license document, but changing it is not allowed.
1185
1186
11870. PREAMBLE
1188
1189The purpose of this License is to make a manual, textbook, or other
1190functional and useful document "free" in the sense of freedom: to
1191assure everyone the effective freedom to copy and redistribute it,
1192with or without modifying it, either commercially or noncommercially.
1193Secondarily, this License preserves for the author and publisher a way
1194to get credit for their work, while not being considered responsible
1195for modifications made by others.
1196
1197This License is a kind of "copyleft", which means that derivative
1198works of the document must themselves be free in the same sense. It
1199complements the GNU General Public License, which is a copyleft
1200license designed for free software.
1201
1202We have designed this License in order to use it for manuals for free
1203software, because free software needs free documentation: a free
1204program should come with manuals providing the same freedoms that the
1205software does. But this License is not limited to software manuals;
1206it can be used for any textual work, regardless of subject matter or
1207whether it is published as a printed book. We recommend this License
1208principally for works whose purpose is instruction or reference.
1209
1210
12111. APPLICABILITY AND DEFINITIONS
1212
1213This License applies to any manual or other work, in any medium, that
1214contains a notice placed by the copyright holder saying it can be
1215distributed under the terms of this License. Such a notice grants a
1216world-wide, royalty-free license, unlimited in duration, to use that
1217work under the conditions stated herein. The "Document", below,
1218refers to any such manual or work. Any member of the public is a
1219licensee, and is addressed as "you". You accept the license if you
1220copy, modify or distribute the work in a way requiring permission
1221under copyright law.
1222
1223A "Modified Version" of the Document means any work containing the
1224Document or a portion of it, either copied verbatim, or with
1225modifications and/or translated into another language.
1226
1227A "Secondary Section" is a named appendix or a front-matter section of
1228the Document that deals exclusively with the relationship of the
1229publishers or authors of the Document to the Document's overall subject
1230(or to related matters) and contains nothing that could fall directly
1231within that overall subject. (Thus, if the Document is in part a
1232textbook of mathematics, a Secondary Section may not explain any
1233mathematics.) The relationship could be a matter of historical
1234connection with the subject or with related matters, or of legal,
1235commercial, philosophical, ethical or political position regarding
1236them.
1237
1238The "Invariant Sections" are certain Secondary Sections whose titles
1239are designated, as being those of Invariant Sections, in the notice
1240that says that the Document is released under this License. If a
1241section does not fit the above definition of Secondary then it is not
1242allowed to be designated as Invariant. The Document may contain zero
1243Invariant Sections. If the Document does not identify any Invariant
1244Sections then there are none.
1245
1246The "Cover Texts" are certain short passages of text that are listed,
1247as Front-Cover Texts or Back-Cover Texts, in the notice that says that
1248the Document is released under this License. A Front-Cover Text may
1249be at most 5 words, and a Back-Cover Text may be at most 25 words.
1250
1251A "Transparent" copy of the Document means a machine-readable copy,
1252represented in a format whose specification is available to the
1253general public, that is suitable for revising the document
1254straightforwardly with generic text editors or (for images composed of
1255pixels) generic paint programs or (for drawings) some widely available
1256drawing editor, and that is suitable for input to text formatters or
1257for automatic translation to a variety of formats suitable for input
1258to text formatters. A copy made in an otherwise Transparent file
1259format whose markup, or absence of markup, has been arranged to thwart
1260or discourage subsequent modification by readers is not Transparent.
1261An image format is not Transparent if used for any substantial amount
1262of text. A copy that is not "Transparent" is called "Opaque".
1263
1264Examples of suitable formats for Transparent copies include plain
1265ASCII without markup, Texinfo input format, LaTeX input format, SGML
1266or XML using a publicly available DTD, and standard-conforming simple
1267HTML, PostScript or PDF designed for human modification. Examples of
1268transparent image formats include PNG, XCF and JPG. Opaque formats
1269include proprietary formats that can be read and edited only by
1270proprietary word processors, SGML or XML for which the DTD and/or
1271processing tools are not generally available, and the
1272machine-generated HTML, PostScript or PDF produced by some word
1273processors for output purposes only.
1274
1275The "Title Page" means, for a printed book, the title page itself,
1276plus such following pages as are needed to hold, legibly, the material
1277this License requires to appear in the title page. For works in
1278formats which do not have any title page as such, "Title Page" means
1279the text near the most prominent appearance of the work's title,
1280preceding the beginning of the body of the text.
1281
1282A section "Entitled XYZ" means a named subunit of the Document whose
1283title either is precisely XYZ or contains XYZ in parentheses following
1284text that translates XYZ in another language. (Here XYZ stands for a
1285specific section name mentioned below, such as "Acknowledgements",
1286"Dedications", "Endorsements", or "History".) To "Preserve the Title"
1287of such a section when you modify the Document means that it remains a
1288section "Entitled XYZ" according to this definition.
1289
1290The Document may include Warranty Disclaimers next to the notice which
1291states that this License applies to the Document. These Warranty
1292Disclaimers are considered to be included by reference in this
1293License, but only as regards disclaiming warranties: any other
1294implication that these Warranty Disclaimers may have is void and has
1295no effect on the meaning of this License.
1296
1297
12982. VERBATIM COPYING
1299
1300You may copy and distribute the Document in any medium, either
1301commercially or noncommercially, provided that this License, the
1302copyright notices, and the license notice saying this License applies
1303to the Document are reproduced in all copies, and that you add no other
1304conditions whatsoever to those of this License. You may not use
1305technical measures to obstruct or control the reading or further
1306copying of the copies you make or distribute. However, you may accept
1307compensation in exchange for copies. If you distribute a large enough
1308number of copies you must also follow the conditions in section 3.
1309
1310You may also lend copies, under the same conditions stated above, and
1311you may publicly display copies.
1312
1313
13143. COPYING IN QUANTITY
1315
1316If you publish printed copies (or copies in media that commonly have
1317printed covers) of the Document, numbering more than 100, and the
1318Document's license notice requires Cover Texts, you must enclose the
1319copies in covers that carry, clearly and legibly, all these Cover
1320Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
1321the back cover. Both covers must also clearly and legibly identify
1322you as the publisher of these copies. The front cover must present
1323the full title with all words of the title equally prominent and
1324visible. You may add other material on the covers in addition.
1325Copying with changes limited to the covers, as long as they preserve
1326the title of the Document and satisfy these conditions, can be treated
1327as verbatim copying in other respects.
1328
1329If the required texts for either cover are too voluminous to fit
1330legibly, you should put the first ones listed (as many as fit
1331reasonably) on the actual cover, and continue the rest onto adjacent
1332pages.
1333
1334If you publish or distribute Opaque copies of the Document numbering
1335more than 100, you must either include a machine-readable Transparent
1336copy along with each Opaque copy, or state in or with each Opaque copy
1337a computer-network location from which the general network-using
1338public has access to download using public-standard network protocols
1339a complete Transparent copy of the Document, free of added material.
1340If you use the latter option, you must take reasonably prudent steps,
1341when you begin distribution of Opaque copies in quantity, to ensure
1342that this Transparent copy will remain thus accessible at the stated
1343location until at least one year after the last time you distribute an
1344Opaque copy (directly or through your agents or retailers) of that
1345edition to the public.
1346
1347It is requested, but not required, that you contact the authors of the
1348Document well before redistributing any large number of copies, to give
1349them a chance to provide you with an updated version of the Document.
1350
1351
13524. MODIFICATIONS
1353
1354You may copy and distribute a Modified Version of the Document under
1355the conditions of sections 2 and 3 above, provided that you release
1356the Modified Version under precisely this License, with the Modified
1357Version filling the role of the Document, thus licensing distribution
1358and modification of the Modified Version to whoever possesses a copy
1359of it. In addition, you must do these things in the Modified Version:
1360
1361A. Use in the Title Page (and on the covers, if any) a title distinct
1362 from that of the Document, and from those of previous versions
1363 (which should, if there were any, be listed in the History section
1364 of the Document). You may use the same title as a previous version
1365 if the original publisher of that version gives permission.
1366B. List on the Title Page, as authors, one or more persons or entities
1367 responsible for authorship of the modifications in the Modified
1368 Version, together with at least five of the principal authors of the
1369 Document (all of its principal authors, if it has fewer than five),
1370 unless they release you from this requirement.
1371C. State on the Title page the name of the publisher of the
1372 Modified Version, as the publisher.
1373D. Preserve all the copyright notices of the Document.
1374E. Add an appropriate copyright notice for your modifications
1375 adjacent to the other copyright notices.
1376F. Include, immediately after the copyright notices, a license notice
1377 giving the public permission to use the Modified Version under the
1378 terms of this License, in the form shown in the Addendum below.
1379G. Preserve in that license notice the full lists of Invariant Sections
1380 and required Cover Texts given in the Document's license notice.
1381H. Include an unaltered copy of this License.
1382I. Preserve the section Entitled "History", Preserve its Title, and add
1383 to it an item stating at least the title, year, new authors, and
1384 publisher of the Modified Version as given on the Title Page. If
1385 there is no section Entitled "History" in the Document, create one
1386 stating the title, year, authors, and publisher of the Document as
1387 given on its Title Page, then add an item describing the Modified
1388 Version as stated in the previous sentence.
1389J. Preserve the network location, if any, given in the Document for
1390 public access to a Transparent copy of the Document, and likewise
1391 the network locations given in the Document for previous versions
1392 it was based on. These may be placed in the "History" section.
1393 You may omit a network location for a work that was published at
1394 least four years before the Document itself, or if the original
1395 publisher of the version it refers to gives permission.
1396K. For any section Entitled "Acknowledgements" or "Dedications",
1397 Preserve the Title of the section, and preserve in the section all
1398 the substance and tone of each of the contributor acknowledgements
1399 and/or dedications given therein.
1400L. Preserve all the Invariant Sections of the Document,
1401 unaltered in their text and in their titles. Section numbers
1402 or the equivalent are not considered part of the section titles.
1403M. Delete any section Entitled "Endorsements". Such a section
1404 may not be included in the Modified Version.
1405N. Do not retitle any existing section to be Entitled "Endorsements"
1406 or to conflict in title with any Invariant Section.
1407O. Preserve any Warranty Disclaimers.
1408
1409If the Modified Version includes new front-matter sections or
1410appendices that qualify as Secondary Sections and contain no material
1411copied from the Document, you may at your option designate some or all
1412of these sections as invariant. To do this, add their titles to the
1413list of Invariant Sections in the Modified Version's license notice.
1414These titles must be distinct from any other section titles.
1415
1416You may add a section Entitled "Endorsements", provided it contains
1417nothing but endorsements of your Modified Version by various
1418parties--for example, statements of peer review or that the text has
1419been approved by an organization as the authoritative definition of a
1420standard.
1421
1422You may add a passage of up to five words as a Front-Cover Text, and a
1423passage of up to 25 words as a Back-Cover Text, to the end of the list
1424of Cover Texts in the Modified Version. Only one passage of
1425Front-Cover Text and one of Back-Cover Text may be added by (or
1426through arrangements made by) any one entity. If the Document already
1427includes a cover text for the same cover, previously added by you or
1428by arrangement made by the same entity you are acting on behalf of,
1429you may not add another; but you may replace the old one, on explicit
1430permission from the previous publisher that added the old one.
1431
1432The author(s) and publisher(s) of the Document do not by this License
1433give permission to use their names for publicity for or to assert or
1434imply endorsement of any Modified Version.
1435
1436
14375. COMBINING DOCUMENTS
1438
1439You may combine the Document with other documents released under this
1440License, under the terms defined in section 4 above for modified
1441versions, provided that you include in the combination all of the
1442Invariant Sections of all of the original documents, unmodified, and
1443list them all as Invariant Sections of your combined work in its
1444license notice, and that you preserve all their Warranty Disclaimers.
1445
1446The combined work need only contain one copy of this License, and
1447multiple identical Invariant Sections may be replaced with a single
1448copy. If there are multiple Invariant Sections with the same name but
1449different contents, make the title of each such section unique by
1450adding at the end of it, in parentheses, the name of the original
1451author or publisher of that section if known, or else a unique number.
1452Make the same adjustment to the section titles in the list of
1453Invariant Sections in the license notice of the combined work.
1454
1455In the combination, you must combine any sections Entitled "History"
1456in the various original documents, forming one section Entitled
1457"History"; likewise combine any sections Entitled "Acknowledgements",
1458and any sections Entitled "Dedications". You must delete all sections
1459Entitled "Endorsements".
1460
1461
14626. COLLECTIONS OF DOCUMENTS
1463
1464You may make a collection consisting of the Document and other documents
1465released under this License, and replace the individual copies of this
1466License in the various documents with a single copy that is included in
1467the collection, provided that you follow the rules of this License for
1468verbatim copying of each of the documents in all other respects.
1469
1470You may extract a single document from such a collection, and distribute
1471it individually under this License, provided you insert a copy of this
1472License into the extracted document, and follow this License in all
1473other respects regarding verbatim copying of that document.
1474
1475
14767. AGGREGATION WITH INDEPENDENT WORKS
1477
1478A compilation of the Document or its derivatives with other separate
1479and independent documents or works, in or on a volume of a storage or
1480distribution medium, is called an "aggregate" if the copyright
1481resulting from the compilation is not used to limit the legal rights
1482of the compilation's users beyond what the individual works permit.
1483When the Document is included in an aggregate, this License does not
1484apply to the other works in the aggregate which are not themselves
1485derivative works of the Document.
1486
1487If the Cover Text requirement of section 3 is applicable to these
1488copies of the Document, then if the Document is less than one half of
1489the entire aggregate, the Document's Cover Texts may be placed on
1490covers that bracket the Document within the aggregate, or the
1491electronic equivalent of covers if the Document is in electronic form.
1492Otherwise they must appear on printed covers that bracket the whole
1493aggregate.
1494
1495
14968. TRANSLATION
1497
1498Translation is considered a kind of modification, so you may
1499distribute translations of the Document under the terms of section 4.
1500Replacing Invariant Sections with translations requires special
1501permission from their copyright holders, but you may include
1502translations of some or all Invariant Sections in addition to the
1503original versions of these Invariant Sections. You may include a
1504translation of this License, and all the license notices in the
1505Document, and any Warranty Disclaimers, provided that you also include
1506the original English version of this License and the original versions
1507of those notices and disclaimers. In case of a disagreement between
1508the translation and the original version of this License or a notice
1509or disclaimer, the original version will prevail.
1510
1511If a section in the Document is Entitled "Acknowledgements",
1512"Dedications", or "History", the requirement (section 4) to Preserve
1513its Title (section 1) will typically require changing the actual
1514title.
1515
1516
15179. TERMINATION
1518
1519You may not copy, modify, sublicense, or distribute the Document except
1520as expressly provided for under this License. Any other attempt to
1521copy, modify, sublicense or distribute the Document is void, and will
1522automatically terminate your rights under this License. However,
1523parties who have received copies, or rights, from you under this
1524License will not have their licenses terminated so long as such
1525parties remain in full compliance.
1526
1527
152810. FUTURE REVISIONS OF THIS LICENSE
1529
1530The Free Software Foundation may publish new, revised versions
1531of the GNU Free Documentation License from time to time. Such new

1535
1536Each version of the License is given a distinguishing version number.
1537If the Document specifies that a particular numbered version of this

1539following the terms and conditions either of that specified version or
1540of any later version that has been published (not as a draft) by the
1541Free Software Foundation. If the Document does not specify a version
1542number of this License, you may choose any version ever published (not

1551
1552 Copyright (c) YEAR YOUR NAME.
1553 Permission is granted to copy, distribute and/or modify this document
1554 under the terms of the GNU Free Documentation License, Version 1.2

1559
1560If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
1561replace the "with...Texts." line with this:

1565
1566If you have Invariant Sections without Cover Texts, or some other
1567combination of the three, merge those two alternatives to suit the
