From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

It allows blind users to interact with applications on the +linux console by means of synthetic speech. + +Currently, speakup has several issues we know of. + +The first issue has to do with the way speakup communicates with serial +ports. Currently, we communicate directly with the hardware +ports. This however conflicts with the standard serial port drivers, +which poses various problems. This is also not working for modern hardware +such as PCI-based serial ports. Also, there is not a way we can +communicate with USB devices. The current serial port handling code is +in serialio.c in this directory. + +Some places are currently using in_atomic() because speakup functions +are called in various contexts, and a couple of things can't happen +in these cases. Pushing work to some worker thread would probably help, +as was already done for the serial port driving part. + +There is a duplication of the selection functions in selections.c. These +functions should get exported from drivers/char/selection.c (clear_selection +notably) and used from there instead. + +The kobjects may have to move to a more proper place in /sys. The +discussion on lkml resulted to putting speech synthesizers in the +"speech" class, and the speakup screen reader itself into +/sys/class/vtconsole/vtcon0/speakup, the nasty path being handled by +userland tools. + +Another issue seems to only happen on SMP systems.

A +copy of the license is included in the section entitled "GNU Free +Documentation License". + +Preface + +The purpose of this document is to familiarize users with the user +interface to Speakup, a Linux Screen Reader. If you need instructions +for installing or obtaining Speakup, visit the web site at +http://linux-speakup.org/. Speakup is a set of patches to the standard +Linux kernel source tree. It can be built as a series of modules, or as +a part of a monolithic kernel. These details are beyond the scope of +this manual, but the user may need to be aware of the module +capabilities, depending on how your system administrator has installed +Speakup. If Speakup is built as a part of a monolithic kernel, and the +user is using a hardware synthesizer, then Speakup will be able to +provide speech access from the time the kernel is loaded, until the time +the system is shutdown. This means that if you have obtained Linux +installation media for a distribution which includes Speakup as a part +of its kernel, you will be able, as a blind person, to install Linux +with speech access unaided by a sighted person. Again, these details +are beyond the scope of this manual, but the user should be aware of +them. See the web site mentioned above for further details. + +1. Starting Speakup + +If your system administrator has installed Speakup to work with your +specific synthesizer by default, then all you need to do to use Speakup +is to boot your system, and Speakup should come up talking. This +assumes of course that your synthesizer is a supported hardware +synthesizer, and that it is either installed in or connected to your +system, and is if necessary powered on. + +It is possible, however, that Speakup may have been compiled into the +kernel with no default synthesizer. It is even possible that your +kernel has been compiled with support for some of the supported +synthesizers and not others. If you find that this is the case, and +your synthesizer is supported but not available, complain to the person +who compiled and installed your kernel. Or better yet, go to the web +site, and learn how to patch Speakup into your own kernel source, and +build and install your own kernel. + +If your kernel has been compiled with Speakup, and has no default +synthesizer set, or you would like to use a different synthesizer than +the default one, then you may issue the following command at the boot +prompt of your boot loader. + +linux speakup.synth=ltlk + +This command would tell Speakup to look for and use a LiteTalk or +DoubleTalk LT at boot up. You may replace the ltlk synthesizer keyword +with the keyword for whatever synthesizer you wish to use. The +speakup.synth parameter will accept the following keywords, provided +that support for the related synthesizers has been built into the +kernel. + +acntsa -- Accent SA +acntpc -- Accent PC +apollo -- Apollo +audptr -- Audapter +bns -- Braille 'n Speak +dectlk -- DecTalk Express (old and new, db9 serial only) +decext -- DecTalk (old) External +dtlk -- DoubleTalk PC +keypc -- Keynote Gold PC +ltlk -- DoubleTalk LT, LiteTalk, or external Tripletalk (db9 serial only) +spkout -- Speak Out +txprt -- Transport +dummy -- Plain text terminal + +Note: Speakup does * NOT * support usb connections! Speakup also does * +NOT * support the internal Tripletalk! + +Speakup does support two other synthesizers, but because they work in +conjunction with other software, they must be loaded as modules after +their related software is loaded, and so are not available at boot up. +These are as follows: + +decpc -- DecTalk PC (not available at boot up) +soft -- One of several software synthesizers (not available at boot up) + +See the sections on loading modules and software synthesizers later in +this manual for further details. It should be noted here that the +speakup.synth boot parameter will have no effect if Speakup has been +compiled as modules. In order for Speakup modules to be loaded during +the boot process, such action must be configured by your system +administrator. This will mean that you will hear some, but not all, of +the bootup messages. + +2. Basic operation + +Once you have booted the system, and if necessary, have supplied the +proper bootup parameter for your synthesizer, Speakup will begin +talking as soon as the kernel is loaded. In fact, it will talk a lot! +It will speak all the boot up messages that the kernel prints on the +screen during the boot process. This is because Speakup is not a +separate screen reader, but is actually built into the operating +system. Since almost all console applications must print text on the +screen using the kernel, and must get their keyboard input through the +kernel, they are automatically handled properly by Speakup. There are a +few exceptions, but we'll come to those later. + +Note: In this guide I will refer to the numeric keypad as the keypad. +This is done because the speakupmap.map file referred to later in this +manual uses the term keypad instead of numeric keypad. Also I'm lazy +and would rather only type one word. So keypad it is. Got it? Good. + +Most of the Speakup review keys are located on the keypad at the far +right of the keyboard. The numlock key should be off, in order for these +to work. If you toggle the numlock on, the keypad will produce numbers, +which is exactly what you want for spreadsheets and such. For the +purposes of this guide, you should have the numlock turned off, which is +its default state at bootup. + +You probably won't want to listen to all the bootup messages every time +you start your system, though it's a good idea to listen to them at +least once, just so you'll know what kind of information is available to +you during the boot process. You can always review these messages after +bootup with the command: + +dmesg | more + +In order to speed the boot process, and to silence the speaking of the +bootup messages, just press the keypad enter key. This key is located +in the bottom right corner of the keypad. Speakup will shut up and stay +that way, until you press another key. + +You can check to see if the boot process has completed by pressing the 8 +key on the keypad, which reads the current line. This also has the +effect of starting Speakup talking again, so you can press keypad enter +to silence it again if the boot process has not completed. + +When the boot process is complete, you will arrive at a "login" prompt. +At this point, you'll need to type in your user id and password, as +provided by your system administrator. You will hear Speakup speak the +letters of your user id as you type it, but not the password. This is +because the password is not displayed on the screen for security +reasons. This has nothing to do with Speakup, it's a Linux security +feature. + +Once you've logged in, you can run any Linux command or program which is +allowed by your user id. Normal users will not be able to run programs +which require root privileges. + +When you are running a program or command, Speakup will automatically +speak new text as it arrives on the screen. You can at any time silence +the speech with keypad enter, or use any of the Speakup review keys. + +Here are some basic Speakup review keys, and a short description of what +they do. + +keypad 1 -- read previous character +keypad 2 -- read current character (pressing keypad 2 twice rapidly will speak + the current character phonetically) +keypad 3 -- read next character +keypad 4 -- read previous word +keypad 5 -- read current word (press twice rapidly to spell the current word) +keypad 6 -- read next word +keypad 7 -- read previous line +keypad 8 -- read current line (press twice rapidly to hear how much the + text on the current line is indented) +keypad 9 -- read next line +keypad period -- speak current cursor position and announce current + virtual console + +It's also worth noting that the insert key on the keypad is mapped +as the speakup key. Instead of pressing and releasing this key, as you +do under DOS or Windows, you hold it like a shift key, and press other +keys in combination with it. For example, repeatedly holding keypad +insert, from now on called speakup, and keypad enter will toggle the +speaking of new text on the screen on and off. This is not the same as +just pressing keypad enter by itself, which just silences the speech +until you hit another key. When you hit speakup plus keypad enter, +Speakup will say, "You turned me off.", or "Hey, that's better." When +Speakup is turned off, no new text on the screen will be spoken. You +can still use the reading controls to review the screen however. + +3. Using the Speakup Help System + +In order to enter the Speakup help system, press and hold the speakup +key (remember that this is the keypad insert key), and press the f1 key. +You will hear the message: + +"Press space to leave help, cursor up or down to scroll, or a letter to +go to commands in list." + +When you press the spacebar to leave the help system, you will hear: + +"Leaving help." + +While you are in the Speakup help system, you can scroll up or down +through the list of available commands using the cursor keys. The list +of commands is arranged in alphabetical order. If you wish to jump to +commands in a specific part of the alphabet, you may press the letter of +the alphabet you wish to jump to. + +You can also just explore by typing keyboard keys. Pressing keys will +cause Speakup to speak the command associated with that key. For +example, if you press the keypad 8 key, you will hear: + +"Keypad 8 is line, say current." + +You'll notice that some commands do not have keys assigned to them. +This is because they are very infrequently used commands, and are also +accessible through the sys system. We'll discuss the sys system later +in this manual. + +You'll also notice that some commands have two keys assigned to them. +This is because Speakup has a built in set of alternative key bindings +for laptop users. The alternate speakup key is the caps lock key. You +can press and hold the caps lock key, while pressing an alternate +speakup command key to activate the command. On most laptops, the +numeric keypad is defined as the keys in the j k l area of the keyboard. + +There is usually a function key which turns this keypad function on and +off, and some other key which controls the numlock state. Toggling the +keypad functionality on and off can become a royal pain. So, Speakup +gives you a simple way to get at an alternative set of key mappings for +your laptop. These are also available by default on desktop systems, +because Speakup does not know whether it is running on a desktop or +laptop. So you may choose which set of Speakup keys to use. Some +system administrators may have chosen to compile Speakup for a desktop +system without this set of alternate key bindings, but these details are +beyond the scope of this manual. To use the caps lock for its normal +purpose, hold the shift key while toggling the caps lock on and off. We +should note here, that holding the caps lock key and pressing the z key +will toggle the alternate j k l keypad on and off. + +4. Keys and Their Assigned Commands + +In this section, we'll go through a list of all the speakup keys and +commands. You can also get a list of commands and assigned keys from +the help system. + +The following list was taken from the speakupmap.map file. Key +assignments are on the left of the equal sign, and the associated +Speakup commands are on the right. The designation "spk" means to press +and hold the speakup key, a.k.a. keypad insert, a.k.a. caps lock, while +pressing the other specified key. + +spk key_f9 = punc_level_dec +spk key_f10 = punc_level_inc +spk key_f11 = reading_punc_dec +spk key_f12 = reading_punc_inc +spk key_1 = vol_dec +spk key_2 = vol_inc +spk key_3 = pitch_dec +spk key_4 = pitch_inc +spk key_5 = rate_dec +spk key_6 = rate_inc +key_kpasterisk = toggle_cursoring +spk key_kpasterisk = speakup_goto +spk key_f1 = speakup_help +spk key_f2 = set_win +spk key_f3 = clear_win +spk key_f4 = enable_win +spk key_f5 = edit_some +spk key_f6 = edit_most +spk key_f7 = edit_delim +spk key_f8 = edit_repeat +shift spk key_f9 = edit_exnum + key_kp7 = say_prev_line +spk key_kp7 = left_edge + key_kp8 = say_line +double key_kp8 = say_line_indent +spk key_kp8 = say_from_top + key_kp9 = say_next_line +spk key_kp9 = top_edge + key_kpminus = speakup_parked +spk key_kpminus = say_char_num + key_kp4 = say_prev_word +spk key_kp4 = say_from_left + key_kp5 = say_word +double key_kp5 = spell_word +spk key_kp5 = spell_phonetic + key_kp6 = say_next_word +spk key_kp6 = say_to_right + key_kpplus = say_screen +spk key_kpplus = say_win + key_kp1 = say_prev_char +spk key_kp1 = right_edge + key_kp2 = say_char +spk key_kp2 = say_to_bottom +double key_kp2 = say_phonetic_char + key_kp3 = say_next_char +spk key_kp3 = bottom_edge + key_kp0 = spk_key + key_kpdot = say_position +spk key_kpdot = say_attributes +key_kpenter = speakup_quiet +spk key_kpenter = speakup_off +key_sysrq = speech_kill + key_kpslash = speakup_cut +spk key_kpslash = speakup_paste +spk key_pageup = say_first_char +spk key_pagedown = say_last_char +key_capslock = spk_key + spk key_z = spk_lock +key_leftmeta = spk_key +ctrl spk key_0 = speakup_goto +spk key_u = say_prev_line +spk key_i = say_line +double spk key_i = say_line_indent +spk key_o = say_next_line +spk key_minus = speakup_parked +shift spk key_minus = say_char_num +spk key_j = say_prev_word +spk key_k = say_word +double spk key_k = spell_word +spk key_l = say_next_word +spk key_m = say_prev_char +spk key_comma = say_char +double spk key_comma = say_phonetic_char +spk key_dot = say_next_char +spk key_n = say_position + ctrl spk key_m = left_edge + ctrl spk key_y = top_edge + ctrl spk key_dot = right_edge +ctrl spk key_p = bottom_edge +spk key_apostrophe = say_screen +spk key_h = say_from_left +spk key_y = say_from_top +spk key_semicolon = say_to_right +spk key_p = say_to_bottom +spk key_slash = say_attributes + spk key_enter = speakup_quiet + ctrl spk key_enter = speakup_off + spk key_9 = speakup_cut +spk key_8 = speakup_paste +shift spk key_m = say_first_char + ctrl spk key_semicolon = say_last_char + +5. The Speakup Sys System + +The Speakup screen reader also creates a speakup subdirectory as a part +of the sys system. + +As a convenience, run as root + +ln -s /sys/accessibility/speakup /speakup + +to directly access speakup parameters from /speakup. +You can see these entries by typing the command: + +ls -1 /speakup/* + +If you issue the above ls command, you will get back something like +this: + +/speakup/attrib_bleep +/speakup/bell_pos +/speakup/bleep_time +/speakup/bleeps +/speakup/cursor_time +/speakup/delimiters +/speakup/ex_num +/speakup/key_echo +/speakup/keymap +/speakup/no_interrupt +/speakup/punc_all +/speakup/punc_level +/speakup/punc_most +/speakup/punc_some +/speakup/reading_punc +/speakup/repeats +/speakup/say_control +/speakup/say_word_ctl +/speakup/silent +/speakup/spell_delay +/speakup/synth +/speakup/synth_direct +/speakup/version + +/speakup/i18n: +announcements +characters +chartab +colors +ctl_keys +formatted +function_names +key_names +states + +/speakup/soft: +caps_start +caps_stop +delay_time +direct +freq +full_time +jiffy_delta +pitch +punct +rate +tone +trigger_time +voice +vol + +Notice the two subdirectories of /speakup: /speakup/i18n and +/speakup/soft. +The i18n subdirectory is described in a later section. +The files under /speakup/soft represent settings that are specific to the +driver for the software synthesizer. If you use the LiteTalk, your +synthesizer-specific settings would be found in /speakup/ltlk. In other words, +a subdirectory named /speakup/KWD is created to hold parameters specific +to the device whose keyword is KWD. +These parameters include volume, rate, pitch, and others. + +In addition to using the Speakup hot keys to change such things as +volume, pitch, and rate, you can also echo values to the appropriate +entry in the /speakup directory. This is very useful, since it +lets you control Speakup parameters from within a script. How you +would write such scripts is somewhat beyond the scope of this manual, +but I will include a couple of simple examples here to give you a +general idea of what such scripts can do. + +Suppose for example, that you wanted to control both the punctuation +level and the reading punctuation level at the same time. For +simplicity, we'll call them punc0, punc1, punc2, and punc3. The scripts +might look something like this: + +#!/bin/bash +# punc0 +# set punc and reading punc levels to 0 +echo 0 >/speakup/punc_level +echo 0 >/speakup/reading_punc +echo Punctuation level set to 0. + +#!/bin/bash +# punc1 +# set punc and reading punc levels to 1 +echo 1 >/speakup/punc_level +echo 1 >/speakup/reading_punc +echo Punctuation level set to 1. + +#!/bin/bash +# punc2 +# set punc and reading punc levels to 2 +echo 2 >/speakup/punc_level +echo 2 >/speakup/reading_punc +echo Punctuation level set to 2. + +#!/bin/bash +# punc3 +# set punc and reading punc levels to 3 +echo 3 >/speakup/punc_level +echo 3 >/speakup/reading_punc +echo Punctuation level set to 3. + +If you were to store these four small scripts in a directory in your +path, perhaps /usr/local/bin, and set the permissions to 755 with the +chmod command, then you could change the default reading punc and +punctuation levels at the same time by issuing just one command. For +example, if you were to execute the punc3 command at your shell prompt, +then the reading punc and punc level would both get set to 3. + +I should note that the above scripts were written to work with bash, but +regardless of which shell you use, you should be able to do something +similar. + +The Speakup sys system also has another interesting use. You can echo +Speakup parameters into the sys system in a script during system +startup, and speakup will return to your preferred parameters every time +the system is rebooted. + +Most of the Speakup sys parameters can be manipulated by a regular user +on the system. However, there are a few parameters that are dangerous +enough that they should only be manipulated by the root user on your +system. There are even some parameters that are read only, and cannot +be written to at all. For example, the version entry in the Speakup +sys system is read only. This is because there is no reason for a user +to tamper with the version number which is reported by Speakup. Doing +an ls -l on /speakup/version will return this: + +-r--r--r-- 1 root root 0 Mar 21 13:46 /speakup/version + +As you can see, the version entry in the Speakup sys system is read +only, is owned by root, and belongs to the root group. Doing a cat of +/speakup/version will display the Speakup version number, like +this: + +cat /speakup/version +Speakup v-2.00 CVS: Thu Oct 21 10:38:21 EDT 2004 +synth dtlk version 1.1 + +The display shows the Speakup version number, along with the version +number of the driver for the current synthesizer. + +Looking at entries in the Speakup sys system can be useful in many +ways. For example, you might wish to know what level your volume is set +at. You could type: + +cat /speakup/KWD/vol +# Replace KWD with the keyword for your synthesizer, E.G., ltlk for LiteTalk. +5 + +The number five which comes back is the level at which the synthesizer +volume is set at. + +All the entries in the Speakup sys system are readable, some are +writable by root only, and some are writable by everyone. Unless you +know what you are doing, you should probably leave the ones that are +writable by root only alone. Most of the names are self explanatory. +Vol for controlling volume, pitch for pitch, rate for controlling speaking +rate, etc. If you find one you aren't sure about, you can post a query +on the Speakup list. + +6. Changing Synthesizers + +It is possible to change to a different synthesizer while speakup is +running. In other words, it is not necessary to reboot the system +in order to use a different synthesizer. You can simply echo the +synthesizer keyword to the /speakup/synth sys entry. +Depending on your situation, you may wish to echo none to the synth +sys entry, to disable speech while one synthesizer is disconnected and +a second one is connected in its place. Then echo the keyword for the +new synthesizer into the synth sys entry in order to start speech +with the newly connected synthesizer. See the list of synthesizer +keywords in section 1 to find the keyword which matches your synth. + +7. Loading modules + +As mentioned earlier, Speakup can either be completely compiled into the +kernel, with the exception of the help module, or it can be compiled as +a series of modules. When compiled as modules, Speakup will only be +able to speak some of the bootup messages if your system administrator +has configured the system to load the modules at boo time. The modules +can be loaded after the file systems have been checked and mounted, or +from an initrd. There is a third possibility. Speakup can be compiled +with some components built into the kernel, and others as modules. As +we'll see in the next section, this is particularly useful when you are +working with software synthesizers. + +If Speakup is completely compiled as modules, then you must use the +modprobe command to load Speakup. You do this by loading the module for +the synthesizer driver you wish to use. The driver modules are all +named speakup_, where is the keyword for the +synthesizer you want. So, in order to load the driver for the DecTalk +Express, you would type the following command: + +modprobe speakup_dectlk + +Issuing this command would load the DecTalk Express driver and all other +related Speakup modules necessary to get Speakup up and running. + +To completely unload Speakup, again presuming that it is entirely built +as modules, you would give the command: + +modprobe -r speakup_dectlk + +The above command assumes you were running a DecTalk Express. If you +were using a different synth, then you would substitute its keyword in +place of dectlk. + +If you have multiple drivers loaded, you need to unload all of them, in +order to completely unload Speakup. +For example, if you have loaded both the dectlk and ltlk drivers, use the +command: +modprobe -r speakup_dectlk speakup_ltlk + +You cannot unload the driver for software synthesizers when a user-space +daemon is using /dev/softsynth. First, kill the daemon. Next, remove +the driver with the command: +modprobe -r speakup_soft + +Now, suppose we have a situation where the main Speakup component +is built into the kernel, and some or all of the drivers are built as +modules. Since the main part of Speakup is compiled into the kernel, a +partial Speakup sys system has been created which we can take advantage +of by simply echoing the synthesizer keyword into the +/speakup/synth sys entry. This will cause the kernel to +automatically load the appropriate driver module, and start Speakup +talking. To switch to another synth, just echo a new keyword to the +synth sys entry. For example, to load the DoubleTalk LT driver, +you would type: + +echo ltlk >/speakup/synth + +You can use the modprobe -r command to unload driver modules, regardless +of whether the main part of Speakup has been built into the kernel or +not. + +8. Using Software Synthesizers + +Using a software synthesizer requires that some other software be +installed and running on your system. For this reason, software +synthesizers are not available for use at bootup, or during a system +installation process. +There are two freely-available solutions for software speech: Espeakup and +Speech Dispatcher. +These are described in subsections 8.1 and 8.2, respectively. + +During the rest of this section, we assume that speakup_soft is either +built in to your kernel, or loaded as a module. + +If your system does not have udev installed , before you can use a +software synthesizer, you must have created the /dev/softsynth device. +If you have not already done so, issue the following commands as root: + +cd /dev +mknod softsynth c 10 26 + +While we are at it, we might just as well create the /dev/synth device, +which can be used to let user space programs send information to your +synthesizer. To create /dev/synth, change to the /dev directory, and +issue the following command as root: + +mknod synth c 10 25 + +of both. + +8.1. Espeakup + +Espeakup is a connector between Speakup and the eSpeak software synthesizer. +Espeakup may already be available as a package for your distribution +of Linux. If it is not packaged, you need to install it manually. +You can find it in the contrib/ subdirectory of the Speakup sources. +The filename is espeakup-$VERSION.tar.bz2, where $VERSION +depends on the current release of Espeakup. The Speakup 3.1.2 source +ships with version 0.71 of Espeakup. +The README file included with the Espeakup sources describes the process +of manual installation. + +Assuming that Espeakup is installed, either by the user or by the distributor, +follow these steps to use it. + +Tell Speakup to use the "soft driver: +echo soft > /speakup/synth + +Finally, start the espeakup program. There are two ways to do it. +Both require root privileges. + +If Espeakup was installed as a package for your Linux distribution, +you probably have a distribution-specific script that controls the operation +of the daemon. Look for a file named espeakup under /etc/init.d or +/etc/rc.d. Execute the following command with root privileges: +/etc/init.d/espeakup start +Replace init.d with rc.d, if your distribution uses scripts located under +/etc/rc.d. +Your distribution will also have a procedure for starting daemons at +boot-time, so it is possible to have software speech as soon as user-space +daemons are started by the bootup scripts. +These procedures are not described in this document. + +If you built Espeakup manually, the "make install" step placed the binary +under /usr/bin. +Run the following command as root: +/usr/bin/espeakup +Espeakup should start speaking. + +8.2. Speech Dispatcher + +For this option, you must have a package called +Speech Dispatcher running on your system, and it must be configured to +work with one of its supported software synthesizers. + +Two open source synthesizers you might use are Flite and Festival. You +might also choose to purchase the Software DecTalk from Fonix Sales Inc. +If you run a google search for Fonix, you'll find their web site. + +You can obtain a copy of Speech Dispatcher from free(b)soft at +http://www.freebsoft.org/. Follow the installation instructions that +come with Speech Dispatcher in order to install and configure Speech +Dispatcher. You can check out the web site for your Linux distribution +in order to get a copy of either Flite or Festival. Your Linux +distribution may also have a precompiled Speech Dispatcher package. + +Once you've installed, configured, and tested Speech Dispatcher with your +chosen software synthesizer, you still need one more piece of software +in order to make things work. You need a package called speechd-up. +You get it from the free(b)soft web site mentioned above. After you've +compiled and installed speechd-up, you are almost ready to begin using +your software synthesizer. + +Now you can begin using your software synthesizer. In order to do so, +echo the soft keyword to the synth sys entry like this: + +echo soft >/speakup/synth + +Next run the speechd_up command like this: + +speechd_up & + +Your synth should now start talking, and you should be able to adjust +the pitch, rate, etc. + +9. Using The DecTalk PC Card + +The DecTalk PC card is an ISA card that is inserted into one of the ISA +slots in your computer. It requires that the DecTalk PC software be +installed on your computer, and that the software be loaded onto the +Dectalk PC card before it can be used. + +You can get the dec_pc.tgz file from the linux-speakup.org site. The +dec_pc.tgz file is in the ~ftp/pub/linux/speakup directory. + +After you have downloaded the dec_pc.tgz file, untar it in your home +directory, and read the Readme file in the newly created dec_pc +directory. + +The easiest way to get the software working is to copy the entire dec_pc +directory into /user/local/lib. To do this, su to root in your home +directory, and issue the command: + +cp dec_pc /usr/local/lib + +You will need to copy the dtload command from the dec_pc directory to a +directory in your path. Either /usr/bin or /usr/local/bin is a good +choice. + +You can now run the dtload command in order to load the DecTalk PC +software onto the card. After you have done this, echo the decpc +keyword to the synth entry in the sys system like this: + +echo decpc >/speakup/synth + +Your DecTalk PC should start talking, and then you can adjust the pitch, +rate, volume, voice, etc. The voice entry in the Speakup sys system +will accept a number from 0 through 7 for the DecTalk PC synthesizer, +which will give you access to some of the DecTalk voices. + +10. Using Cursor Tracking + +In Speakup version 2.0 and later, cursor tracking is turned on by +default. This means that when you are using an editor, Speakup will +automatically speak characters as you move left and right with the +cursor keys, and lines as you move up and down with the cursor keys. +This is the traditional sort of cursor tracking. +Recent versions of Speakup provide two additional ways to control the +text that is spoken when the cursor is moved: +"highlight tracking" and "read window." +They are described later in this section. +Sometimes, these modes get in your way, so you can disable cursor tracking +altogether. + +You may select among the various forms of cursor tracking using the keypad +asterisk key. +Each time you press this key, a new mode is selected, and Speakup speaks +the name of the new mode. The names for the four possible states of cursor +tracking are: "cursoring on", "highlight tracking", "read window", +and "cursoring off." The keypad asterisk key moves through the list of +modes in a circular fashion. + +If highlight tracking is enabled, Speakup tracks highlighted text, +rather than the cursor itself. When you move the cursor with the arrow keys, +Speakup speaks the currently highlighted information. +This is useful when moving through various menus and dialog boxes. +If cursor tracking isn't helping you while navigating a menu, +try highlight tracking. + +With the "read window" variety of cursor tracking, you can limit the text +that Speakup speaks by specifying a window of interest on the screen. +See section 15 for a description of the process of defining windows. +When you move the cursor via the arrow keys, Speakup only speaks +the contents of the window. This is especially helpful when you are hearing +superfluous speech. Consider the following example. + +Suppose that you are at a shell prompt. You use bash, and you want to +explore your command history using the up and down arrow keys. If you +have enabled cursor tracking, you will hear two pieces of information. +Speakup speaks both your shell prompt and the current entry from the +command history. You may not want to hear the prompt repeated +each time you move, so you can silence it by specifying a window. Find +the last line of text on the screen. Clear the current window by pressing +the key combination speakup f3. Use the review cursor to find the first +character that follows your shell prompt. Press speakup + f2 twice, to +define a one-line window. The boundaries of the window are the +character following the shell prompt and the end of the line. Now, cycle +through the cursor tracking modes using keypad asterisk, until Speakup +says "read window." Move through your history using your arrow keys. +You will notice that Speakup no longer speaks the redundant prompt. + +Some folks like to turn cursor tracking off while they are using the +lynx web browser. You definitely want to turn cursor tracking off when +you are using the alsamixer application. Otherwise, you won't be able +to hear your mixer settings while you are using the arrow keys. + +11. Cut and Paste + +One of Speakup's more useful features is the ability to cut and paste +text on the screen. This means that you can capture information from a +program, and paste that captured text into a different place in the +program, or into an entirely different program, which may even be +running on a different console. + +For example, in this manual, we have made references to several web +sites. It would be nice if you could cut and paste these urls into your +web browser. Speakup does this quite nicely. Suppose you wanted to +past the following url into your browser: + +http://linux-speakup.org/ + +Use the speakup review keys to position the reading cursor on the first +character of the above url. When the reading cursor is in position, +press the keypad slash key once. Speakup will say, "mark". Next, +position the reading cursor on the rightmost character of the above +url. Press the keypad slash key once again to actually cut the text +from the screen. Speakup will say, "cut". Although we call this +cutting, Speakup does not actually delete the cut text from the screen. +It makes a copy of the text in a special buffer for later pasting. + +Now that you have the url cut from the screen, you can paste it into +your browser, or even paste the url on a command line as an argument to +your browser. + +Suppose you want to start lynx and go to the Speakup site. + +You can switch to a different console with the alt left and right +arrows, or you can switch to a specific console by typing alt and a +function key. These are not Speakup commands, just standard Linux +console capabilities. + +Once you've changed to an appropriate console, and are at a shell prompt, +type the word lynx, followed by a space. Now press and hold the speakup +key, while you type the keypad slash character. The url will be pasted +onto the command line, just as though you had typed it in. Press the +enter key to execute the command. + +The paste buffer will continue to hold the cut information, until a new +mark and cut operation is carried out. This means you can paste the cut +information as many times as you like before doing another cut +operation. + +You are not limited to cutting and pasting only one line on the screen. +You can also cut and paste rectangular regions of the screen. Just +position the reading cursor at the top left corner of the text to be +cut, mark it with the keypad slash key, then position the reading cursor +at the bottom right corner of the region to be cut, and cut it with the +keypad slash key. + +12. Changing the Pronunciation of Characters + +Through the /speakup/i18n/characters sys entry, Speakup gives you the +ability to change how Speakup pronounces a given character. You could, +for example, change how some punctuation characters are spoken. You can +even change how Speakup will pronounce certain letters. + +You may, for example, wish to change how Speakup pronounces the z +character. The author of Speakup, Kirk Reiser, is Canadian, and thus +believes that the z should be pronounced zed. If you are an American, +you might wish to use the zee pronunciation instead of zed. You can +change the pronunciation of both the upper and lower case z with the +following two commands: + +echo 90 zee >/speakup/characters +echo 122 zee >/speakup/characters + +Let's examine the parts of the two previous commands. They are issued +at the shell prompt, and could be placed in a startup script. + +The word echo tells the shell that you want to have it display the +string of characters that follow the word echo. If you were to just +type: + +echo hello. + +You would get the word hello printed on your screen as soon as you +pressed the enter key. In this case, we are echoing strings that we +want to be redirected into the sys system. + +The numbers 90 and 122 in the above echo commands are the ascii numeric +values for the upper and lower case z, the characters we wish to change. + +The string zee is the pronunciation that we want Speakup to use for the +upper and lower case z. + +The > symbol redirects the output of the echo command to a file, just +like in DOS, or at the Windows command prompt. + +And finally, /speakup/i18n/characters is the file entry in the sys system +where we want the output to be directed. Speakup looks at the numeric +value of the character we want to change, and inserts the pronunciation +string into an internal table. + +You can look at the whole table with the following command: + +cat /speakup/i18n/characters + +Speakup will then print out the entire character pronunciation table. I +won't display it here, but leave you to look at it at your convenience. + +13. Mapping Keys + +Speakup has the capability of allowing you to assign or "map" keys to +internal Speakup commands. This section necessarily assumes you have a +Linux kernel source tree installed, and that it has been patched and +configured with Speakup. How you do this is beyond the scope of this +manual. For this information, visit the Speakup web site at +http://linux-speakup.org/. The reason you'll need the kernel source +tree patched with Speakup is that the genmap utility you'll need for +processing keymaps is in the +/usr/src/linux-/drivers/char/speakup directory. The + in the above directory path is the version number of +the Linux source tree you are working with. + +So ok, you've gone off and gotten your kernel source tree, and patched +and configured it. Now you can start manipulating keymaps. + +You can either use the +/usr/src/linux-/drivers/char/speakup/speakupmap.map file +included with the Speakup source, or you can cut and paste the copy in +section 4 into a separate file. If you use the one in the Speakup +source tree, make sure you make a backup of it before you start making +changes. You have been warned! + +Suppose that you want to swap the key assignments for the Speakup +say_last_char and the Speakup say_first_char commands. The +speakupmap.map lists the key mappings for these two commands as follows: + +spk key_pageup = say_first_char +spk key_pagedown = say_last_char + +You can edit your copy of the speakupmap.map file and swap the command +names on the right side of the = (equals) sign. You did make a backup, +right? The new keymap lines would look like this: + +spk key_pageup = say_last_char +spk key_pagedown = say_first_char + +After you edit your copy of the speakupmap.map file, save it under a new +file name, perhaps newmap.map. Then exit your editor and return to the +shell prompt. + +You are now ready to load your keymap with your swapped key assignments. + Assuming that you saved your new keymap as the file newmap.map, you +would load your keymap into the sys system like this: + +/usr/src/linux-/drivers/char/speakup/genmap newmap.map +>/speakup/keymap + +Remember to substitute your kernel version number for the + in the above command. Also note that although the +above command wrapped onto two lines in this document, you should type +it all on one line. + +Your say first and say last characters should now be swapped. Pressing +speakup pagedown should read you the first non-whitespace character on +the line your reading cursor is in, and pressing speakup pageup should +read you the last character on the line your reading cursor is in. + +You should note that these new mappings will only stay in effect until +you reboot, or until you load another keymap. + +One final warning. If you try to load a partial map, you will quickly +find that all the mappings you didn't include in your file got deleted +from the working map. Be extremely careful, and always make a backup! +You have been warned! + +14. Internationalizing Speakup + +Speakup indicates various conditions to the user by speaking messages. +For instance, when you move to the left edge of the screen with the +review keys, Speakup says, "left." +Prior to version 3.1.0 of Speakup, all of these messages were in English, +and they could not be changed. If you used a non-English synthesizer, +you still heard English messages, such as "left" and "cursoring on." +In version 3.1.0 or higher, one may load translations for the various +messages via the /sys filesystem. + +The directory /speakup/i18n contains several collections of messages. +Each group of messages is stored in its own file. +The following section lists all of these files, along with a brief description +of each. + +14.1. Files Under the i18n Subdirectory + +* announcements: +This file contains various general announcements, most of which cannot +be categorized. You will find messages such as "You killed Speakup", +"I'm alive", "leaving help", "parked", "unparked", and others. +You will also find the names of the screen edges and cursor tracking modes +here. + +* characters: +See section 12 for a description of this file. + +* chartab: +See section 12. Unlike the rest of the files in the i18n subdirectory, +this one does not contain messages to be spoken. + +* colors: +When you use the "say attributes" function, Speakup says the name of the +foreground and background colors. These names come from the i18n/colors +file. + +* ctl_keys: +Here, you will find names of control keys. These are used with Speakup's +say_control feature. + +* formatted: +This group of messages contains embedded formatting codes, to specify +the type and width of displayed data. If you change these, you must +preserve all of the formatting codes, and they must appear in the order +used by the default messages. + +* function_names: +Here, you will find a list of names for Speakup functions. These are used +by the help system. For example, suppose that you have activated help mode, +and you pressed keypad 3. Speakup says: +"keypad 3 is character, say next." +The message "character, say next" names a Speakup function, and it +comes from this function_names file. + +* key_names: +Again, key_names is used by Speakup's help system. In the previous +example, Speakup said that you pressed "keypad 3." +This name came from the key_names file. + +* states: +This file contains names for key states. +Again, these are part of the help system. For instance, if you had pressed +speakup + keypad 3, you would hear: +"speakup keypad 3 is go to bottom edge." +The speakup key is depressed, so the name of the key state is speakup. +This part of the message comes from the states collection. + +14.2. Loading Your Own Messages + +The files under the i18n subdirectory all follow the same format. +They consist of lines, with one message per line. +Each message is represented by a number, followed by the text of the message. +The number is the position of the message in the given collection. +For example, if you view the file /speakup/i18n/colors, you will see the +following list: + +0 black +1 blue +2 green +3 cyan +4 red +5 magenta +6 yellow +7 white +8 grey + +You can change one message, or you can change a whole group. +To load a whole collection of messages from a new source, simply use +the cp command: +cp ~/my_colors /speakup/i18n/colors +You can change an individual message with the echo command, +as shown in the following example. + +The Spanish name for the color blue is azul. +Looking at the colors file, we see that the name "blue" is at position 1 +within the colors group. Let's change blue to azul: +echo '1 azul' > /speakup/i18n/colors +The next time that Speakup says message 1 from the colors group, it will +say "azul", rather than "blue." + +In the future, translations into various languages will be made available, +and most users will just load the files necessary for their language. + +14.3. No Support for Non-Western-European Languages + +As of the current release, Speakup only supports Western European languages. +Support for the extended characters used by languages outside of the Western +European family of languages is a work in progress. + +15. Using Speakup's Windowing Capability + +Speakup has the capability of defining and manipulating windows on the +screen. Speakup uses the term "Window", to mean a user defined area of +the screen. The key strokes for defining and manipulating Speakup +windows are as follows: + +speakup + f2 -- Set the bounds of the window. +Speakup + f3 -- clear the current window definition. +speakup + f4 -- Toggle window silence on and off. +speakup + keypad plus -- Say the currently defined window. + +These capabilities are useful for tracking a certain part of the screen +without rereading the whole screen, or for silencing a part of the +screen that is constantly changing, such as a clock or status line. + +There is no way to save these window settings, and you can only have one +window defined for each virtual console. There is also no way to have +windows automatically defined for specific applications. + +In order to define a window, use the review keys to move your reading +cursor to the beginning of the area you want to define. Then press +speakup + f2. Speakup will tell you that the window starts at the +indicated row and column position. Then move the reading cursor to the +end of the area to be defined as a window, and press speakup + f2 again. + If there is more than one line in the window, Speakup will tell you +that the window ends at the indicated row and column position. If there +is only one line in the window, then Speakup will tell you that the +window is the specified line on the screen. If you are only defining a +one line window, you can just press speakup + f2 twice after placing the +reading cursor on the line you want to define as a window. It is not +necessary to position the reading cursor at the end of the line in order +to define the whole line as a window. + +16. Tools for Controlling Speakup + +The speakup distribution includes extra tools (in the tools directory) +which were written to make speakup easier to use. This section will +briefly describe the use of these tools. + +16.1. Speakupconf + +speakupconf began life as a contribution from Steve Holmes, a member of +the speakup community. We would like to thank him for his work on the +early versions of this project. + +This script may be installed as part of your linux distribution, but if +it isn't, the recommended places to put it are /usr/local/bin or +/usr/bin. This script can be run by any user, so it does not require +root privileges. + +Speakupconf allows you to save and load your Speakup settings. It works +by reading and writing the /sys files described above. + +The directory that speakupconf uses to store your settings depends on +whether it is run from the root account. If you execute speakupconf as +root, it uses the directory /etc/speakup. Otherwise, it uses the directory +~/.speakup, where ~ is your home directory. +Anyone who needs to use Speakup from your console can load his own custom +settings with this script. + +speakupconf takes one required argument: load or save. +Use the command +speakupconf save +to save your Speakup settings, and +speakupconf load +to load them into Speakup. +A second argument may be specified to use an alternate directory to +load or save the speakup parameters. + +16.2. Talkwith + +Charles Hallenbeck, another member of the speakup community, wrote the +initial versions of this script, and we would also like to thank him for +his work on it. + +This script needs root privileges to run, so if it is not installed as +part of your linux distribution, the recommended places to install it +are /usr/local/sbin or /usr/sbin. + +Talkwith allows you to switch synthesizers on the fly. It takes a synthesizer +name as an argument. For instance, +talkwith dectlk +causes Speakup to use the DecTalk Express. If you wish to switch to a +software synthesizer, you must also indicate which daemon you wish to +use. There are two possible choices: +spd and espeakup. spd is an abbreviation for speechd-up. +If you wish to use espeakup for software synthesis, give the command +talkwith soft espeakup +To use speechd-up, type: +talkwith soft spd +Any arguments that follow the name of the daemon are passed to the daemon +when it is invoked. For instance: +talkwith espeakup --default-voice=fr +causes espeakup to use the French voice. +Note that talkwith must always be executed with root privileges. + +Talkwith does not attempt to load your settings after the new +synthesizer is activated. You can use speakupconf to load your settings +if desired. + + GNU Free Documentation License + Version 1.2, November 2002 + + + Copyright (C) 2000,2001,2002 Free Software Foundation, Inc. + 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + +0. PREAMBLE + +The purpose of this License is to make a manual, textbook, or other +functional and useful document "free" in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +Secondarily, this License preserves for the author and publisher a way +to get credit for their work, while not being considered responsible +for modifications made by others. + +This License is a kind of "copyleft", which means that derivative +works of the document must themselves be free in the same sense. It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + + +1. APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The "Document", below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as "you". You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A "Modified Version" of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A "Secondary Section" is a named appendix or a front-matter section of +the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall subject +(or to related matters) and contains nothing that could fall directly +within that overall subject. (Thus, if the Document is in part a +textbook of mathematics, a Secondary Section may not explain any +mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The "Invariant Sections" are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The "Cover Texts" are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A "Transparent" copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not "Transparent" is called "Opaque". + +Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, LaTeX input format, SGML +or XML using a publicly available DTD, and standard-conforming simple +HTML, PostScript or PDF designed for human modification. Examples of +transparent image formats include PNG, XCF and JPG. Opaque formats +include proprietary formats that can be read and edited only by +proprietary word processors, SGML or XML for which the DTD and/or +processing tools are not generally available, and the +machine-generated HTML, PostScript or PDF produced by some word +processors for output purposes only. + +The "Title Page" means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, "Title Page" means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +A section "Entitled XYZ" means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as "Acknowledgements", +"Dedications", "Endorsements", or "History".) To "Preserve the Title" +of such a section when you modify the Document means that it remains a +section "Entitled XYZ" according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + + +2. VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + + +3. COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + + +4. MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +A. Use in the Title Page (and on the covers, if any) a title distinct + from that of the Document, and from those of previous versions + (which should, if there were any, be listed in the History section + of the Document). You may use the same title as a previous version + if the original publisher of that version gives permission. +B. List on the Title Page, as authors, one or more persons or entities + responsible for authorship of the modifications in the Modified + Version, together with at least five of the principal authors of the + Document (all of its principal authors, if it has fewer than five), + unless they release you from this requirement. +C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. +D. Preserve all the copyright notices of the Document. +E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. +F. Include, immediately after the copyright notices, a license notice + giving the public permission to use the Modified Version under the + terms of this License, in the form shown in the Addendum below. +G. Preserve in that license notice the full lists of Invariant Sections + and required Cover Texts given in the Document's license notice. +H. Include an unaltered copy of this License. +I. Preserve the section Entitled "History", Preserve its Title, and add + to it an item stating at least the title, year, new authors, and + publisher of the Modified Version as given on the Title Page. If + there is no section Entitled "History" in the Document, create one + stating the title, year, authors, and publisher of the Document as + given on its Title Page, then add an item describing the Modified + Version as stated in the previous sentence. +J. Preserve the network location, if any, given in the Document for + public access to a Transparent copy of the Document, and likewise + the network locations given in the Document for previous versions + it was based on. These may be placed in the "History" section. + You may omit a network location for a work that was published at + least four years before the Document itself, or if the original + publisher of the version it refers to gives permission. +K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section all + the substance and tone of each of the contributor acknowledgements + and/or dedications given therein. +L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section titles. +M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. +N. Do not retitle any existing section to be Entitled "Endorsements" + or to conflict in title with any Invariant Section. +O. Preserve any Warranty Disclaimers. + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled "Endorsements", provided it contains +nothing but endorsements of your Modified Version by various +parties--for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + + +5. COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled "History" +in the various original documents, forming one section Entitled +"History"; likewise combine any sections Entitled "Acknowledgements", +and any sections Entitled "Dedications". You must delete all sections +Entitled "Endorsements". + + +6. COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + + +7. AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an "aggregate" if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + + +8. TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled "Acknowledgements", +"Dedications", or "History", the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + + +9. TERMINATION + +You may not copy, modify, sublicense, or distribute the Document except +as expressly provided for under this License. Any other attempt to +copy, modify, sublicense or distribute the Document is void, and will +automatically terminate your rights under this License. However, +parties who have received copies, or rights, from you under this +License will not have their licenses terminated so long as such +parties remain in full compliance. + + +10. FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time.
