| 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 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) |
| |
| By default speakup looks for the synthesizer on the ttyS0 serial port. This can |
| be changed with the device parameter of the modules, for instance for |
| DoubleTalk LT: |
| |
| speakup_ltlk.dev=ttyUSB0 |
| |
| 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. |

| |
| 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 |
| inflection |
| 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, inflection for pitch range, 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 boot 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_<keyword>, where <keyword> 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-<version_number>/drivers/char/speakup directory. The |
| <version_number> 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-<version_number>/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-<version_number>/drivers/char/speakup/genmap newmap.map |
| >/speakup/keymap |
| |
| Remember to substitute your kernel version number for the |
| <version_number> 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. Changing language |
| |
| 14.2.1. 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." |
| |
| 14.2.2. Choose a language |
| |
| In the future, translations into various languages will be made available, |
| and most users will just load the files necessary for their language. So far, |
| only French language is available beyond native Canadian English language. |
| |
| French is only available after you are logged in. |
| |
| Canadian English is the default language. To toggle another language, |
| download the source of Speakup and untar it in your home directory. The |
| following command should let you do this: |
| |
| tar xvjf speakup-<version>.tar.bz2 |
| |
| where <version> is the version number of the application. |
| |
| Next, change to the newly created directory, then into the tools/ directory, and |
| run the script speakup_setlocale. You are asked the language that you want to |
| use. Type the number associated to your language (e.g. fr for French) then press |
| Enter. Needed files are copied in the i18n directory. |
| |
| Note: the speakupconf must be installed on your system so that settings are saved. |
| Otherwise, you will have an error: your language will be loaded but you will |
| have to run the script again every time Speakup restarts. |
| See section 16.1. for information about speakupconf. |
| |
| You will have to repeat these steps for any change of locale, i.e. if you wish |
| change the speakup's language or charset (iso-8859-15 ou UTF-8). |
| |
| If you wish store the settings, note that at your next login, you will need to |
| do: |
| |
| speakup load |
| |
| Alternatively, you can add the above line to your file |
| ~/.bashrc or ~/.bash_profile. |
| |
| If your system administrator himself ran the script, all the users will be able |
| to change from English to the language chosen by root and do directly |
| speakupconf load (or add this to the ~/.bashrc or |
| ~/.bash_profile file). If there are several languages to handle, the |
| administrator (or every user) will have to run the first steps until speakupconf |
| save, choosing the appropriate language, in every user's home directory. Every |
| user will then be able to do speakupconf load, Speakup will load his own settings. |
| |
| 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. |

| Version 1.2, November 2002 |
| |
| |
| Copyright (C) 2000,2001,2002 Free Software Foundation, Inc. |
| 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. Such new |
| versions will be similar in spirit to the present version, but may |
| differ in detail to address new problems or concerns. See |
| https://www.gnu.org/copyleft/. |
| |
| Each version of the License is given a distinguishing version number. |
| If the Document specifies that a particular numbered version of this |
| License "or any later version" applies to it, you have the option of |
| following the terms and conditions either of that specified version or |
| of any later version that has been published (not as a draft) by the |
| Free Software Foundation. If the Document does not specify a version |
| number of this License, you may choose any version ever published (not |
| as a draft) by the Free Software Foundation. |
| |
| |
| ADDENDUM: How to use this License for your documents |
| |
| To use this License in a document you have written, include a copy of |
| the License in the document and put the following copyright and |
| license notices just after the title page: |
| |
| Copyright (c) YEAR YOUR NAME. |
| Permission is granted to copy, distribute and/or modify this document |
| under the terms of the GNU Free Documentation License, Version 1.2 |
| or any later version published by the Free Software Foundation; |
| with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. |
| A copy of the license is included in the section entitled "GNU |
| Free Documentation License". |
| |
| If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, |
| replace the "with...Texts." line with this: |
| |
| with the Invariant Sections being LIST THEIR TITLES, with the |
| Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. |
| |
| If you have Invariant Sections without Cover Texts, or some other |
| combination of the three, merge those two alternatives to suit the |
| situation. |
| |
| If your document contains nontrivial examples of program code, we |
| recommend releasing these examples in parallel under your choice of |
| free software license, such as the GNU General Public License, |
| to permit their use in free software. |
| |
| The End. |
