It can be acquired as plain-text to be viewed offline with a pager from @uref{https://carbslinux.org/install.txt}. @example curl -sL https://carbslinux.org/install.txt | less @end example @menu * Preparing Environment:: Getting ready to chroot * Chroot:: Going inside your new system * System Configuration:: Customizing your system for personal use * Kernel:: Compiling your own kernel * Making your system bootable:: Installing bootloader and boot scripts * Post-installation:: Post-installation tasks @end menu @node Preparing Environment @section Preparing Environment To install Carbs Linux, you will need a Live Linux ISO@. For that purpose, you can obtain a Gentoo or Void Linux live image. You can follow their instructions to boot and setup your network. You will need the following programs in order to install Carbs Linux: @itemize @item tar @item wget @item xz @item some form of base utilities (coreutils, sbase, busybox, etc.) @end itemize Rest of these instructions will assume that you have set all of these up, and will continue on that point. @menu * Download:: Download the root filesystem tarball * Signature verification:: Verify the signature of the rootfs tarball * Extracting the tarball:: Extracting the root filesystem to the desired location @end menu @node Download @subsection Download First, we need to download the rootfs tarball. You can do the following in order to obtain the rootfs. If you are using an i686 machine, replace the @samp{x86_64} with @samp{i686}. We are setting this in a URL variable so that we don't have to write it every time. @example URL=https://dl.carbslinux.org/releases/x86_64 wget $URL/carbs-rootfs.tar.xz.sha256 sha256sum -c carbs-rootfs.tar.xz.sha256 @end example @node Signature verification @subsection Signature verification It is highly recommended to verify the signature of the tarball. You will need the OpenBSD tool @samp{signify(1)} for this. Many distributions provide a package for it, if you are using a Carbs Linux host, you can also install the package @samp{otools} which provides @samp{signify}. Download the signature first. @example wget $URL/carbs-rootfs.tar.xz.sig @end example The signature file should say something similar to @example untrusted comment: verify with carbslinux-2023.02.pub RWTe38zmx+iyuKEL5T84MJ5Y24jqenkTtQLJxbaMzOBS/NkGVl5J+Vn2B6vTV/gJK7LYBPS+IOXV5sEf+YLGCMcBYAGHCcP4xQ8= @end example Grab the key (which probably should be the latest one) that is written on the file from @uref{https://dl.carbslinux.org/keys/} so you can verify the signature. The latest Signify public key is also available on the @uref{https://git.carbslinux.org/repository, package repository}, so you can check the validity of the public key from multiple locations, or just copy paste that portion to a file and use that instead. @example PUBKEY=carbslinux-2023.02.pub wget https://dl.carbslinux.org/keys/$PUBKEY @end example You can now verify the distribution tarball with signify. @example signify -V -m carbs-rootfs.tar.xz -p $PUBKEY @end example If everything went alright, this should output: @example Signature Verified @end example @node Extracting the tarball @subsection Extracting the tarball You will need to extract the tarball to your desired location. For partitioning, you can follow @uref{https://wiki.archlinux.org/index.php/Partitioning, this guide}. This will assume that you will be mounting your root partition to @samp{/mnt}. @example mount /dev/sdx1 /mnt tar xf carbs-rootfs.tar.xz -C /mnt @end example @node Chroot @section Chroot Chroot into Carbs Linux by running the chroot helper inside the rootfs! @example /mnt/bin/cpt-chroot /mnt @end example @menu * Setting up repositories:: Basic setup for obtaining repositories * Updating packages:: Update your system * Installing packages:: Install new software on your system * Essential Software:: Software you might want to include on your system * Obtaining the documentation:: Install documentation for offline use (optional) @end menu @node Setting up repositories @subsection Setting up repositories Newest tarballs do not come with repositories, so you will need to manually obtain them, and set your @samp{CPT_PATH} environment variable. Carbs Linux repositories can either be obtained by @samp{git} or @samp{rsync}. While rsync repositories are overall faster and smaller, git offers the whole history of the repository and a means to manipulate your repository as you like it. If you want to obtain the git repository, you will need to install @samp{git} itself. The following guide will assume that you put the repositories into @samp{~/repos/} directory, but you can put the repositories into any directory you want. So go ahead and create that directory: @example mkdir -p $HOME/repos @end example @enumerate @item @anchor{Obtaining from git}Obtaining from git Carbs Linux git repositories can be found both from the main server and GitHub (mirror). Here are both their repository links. You can clone any of them. @itemize @item @uref{https://git.carbslinux.org/repository} @item @uref{https://git.sr.ht/~carbslinux/repository} @end itemize @example git clone git://git.carbslinux.org/repository $HOME/repos/carbs @end example @item @anchor{Obtaining from rsync}Obtaining from rsync Carbs Linux rsync repositories live in rsync://carbslinux.org/repo. In order to obtain it, run the following: @example rsync -avc rsync://vaylin.carbslinux.org/repo $HOME/repos/carbs @end example @item @anchor{Making the package manager use the repositories}Making the package manager use the repositories In your shell's configuration file, or in your @samp{~/.profile} file, add the following lines: @example CPT_PATH=$HOME/repos/carbs/core CPT_PATH=$CPT_PATH:$HOME/repos/carbs/extra CPT_PATH=$CPT_PATH:$HOME/repos/carbs/wayland CPT_PATH=$CPT_PATH:$HOME/repos/carbs/community export CPT_PATH @end example @end enumerate @node Updating packages @subsection Updating packages It is good practice to make sure your system is up to date, especially before building new packages. If there is an update for the package manager you will need to update twice. @example cpt-update && cpt-update @end example @node Installing packages @subsection Installing packages Since you are operating on a really small base, you might need to build and install new programs to extend the functionality of your system. In order to build and install packages new packages in Carbs, you need to execute the following. "Package" is not actually a package and is given as an example. @example cpt-build package cpt-install package @end example @node Essential Software @subsection Essential Software Here is a small list of software that you might want to have on your system as you are setting up. You might want to check the @strong{Software} section in the full documentation to learn more about other packaged software. @strong{BOOTLOADERS} @itemize @item efibootmgr @item grub @end itemize @strong{FILESYSTEMS} @itemize @item e2fsprogs @item dosfstools @item ntfs-3g @end itemize @strong{NETWORKING} @itemize @item dhcpcd @item wpa@math{_supplicant} @end itemize @strong{TEXT EDITORS} @itemize @item nano @item vim @end itemize @strong{DOCUMENTATION} @itemize @item carbs-docs @item man-pages @item man-pages-posix @end itemize @node Obtaining the documentation @subsection Obtaining the documentation All the documentation for Carbs Linux can be found on a single info manual to be viewed offline. You can obtain either @samp{texinfo} or the @samp{info} packages in order to view the documentation. @example # Install the documentation. cpt b carbs-docs && cpt i carbs-docs # Install either texinfo or the info package. We will be installing standalone info # as it doesn't need perl. cpt b info && cpt i info # You can then run info and navigate through the documentation. info carbslinux @end example @node System Configuration @section System Configuration After you have finished installing some extra packages, you can configure your system to your liking. @menu * Configuring hostname:: Setting up system hostname (recommended) * Hosts file:: Setting up hosts file for networking (optional) * Creating a user:: Adding a user to your new system @end menu @node Configuring hostname @subsection Configuring hostname You might want to add a hostname, especially in a networked environment. Your hostname will default to 'carbslinux' unless you set this. @example echo your-hostname > /etc/hostname @end example @node Hosts file @subsection Hosts file You can edit your /etc/hosts file, which is the static lookup table for host names. By default, there are two entries for localhost which are OKAY@. You can replace the 'localhost' part of these entries to your hostname. @example 127.0.0.1 localhost.localdomain localhost ::1 localhost.localdomain localhost ip6-localhost @end example @node Creating a user @subsection Creating a user Creating a new user is not strictly necessary, but it is highly recommended. Especially for building packages, it is the safest option to create an unprivileged user and using @samp{doas} for doing operations that require @samp{root} privileges. The code block below describes how to create a user (named @samp{foo}), add them to the wheel group, and to give doas permissions to the wheel group @example # Create the new user adduser foo # Add the user to the wheel group addgroup foo wheel # Give root permission to the wheel group using doas echo permit persist :wheel >> /etc/doas.conf @end example You are also advised to take a look at the doas configuration file and the manual page of doas. After you are finished you can switch to the new user by running @example su foo @end example @node Kernel @section Kernel Kernel isn't managed under the main repositories, even though you could package one for your personal use. Here is an @uref{https://github.com/cemkeylan/kiss-repository/tree/master/personal/linux, example kernel package}, which you will need to reconfigure for your specific setup if you want to make use of it. @menu * Obtaining the kernel sources:: Downloading the Linux source code * Kernel dependencies:: Requirements for building the kernel * Building the kernel:: Configure and compile the kernel @end menu @node Obtaining the kernel sources @subsection Obtaining the kernel sources You can visit the @uref{https://kernel.org} website to choose a kernel that you want to install. Though only the latest stable and longterm (LTS) versions are supported. Note that kernel releases are quite rapid, and the version below is likely outdated, so don't run it verbatim. @example # Download the kernel and extract it wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.19.4.tar.xz tar xJf linux-5.19.4.tar.xz # Change directory into the kernel sources cd linux-5.19.4 @end example @strong{NOTE:} If you want to validate the kernel signature, install the @samp{gnupg2} package, and follow the instructions provided at @uref{https://kernel.org/category/signatures.html}. @node Kernel dependencies @subsection Kernel dependencies In order to compile the kernel you will need to install some dependencies. You will need @samp{libelf}, and @samp{bison} to compile the kernel. If you want to configure using the menu interface you will also need @samp{ncurses}. @example # The package manager asks to install if you are building more than one package, # so no need to run 'cpt i ...' cpt b libelf ncurses @end example In the vanilla kernel sources, you need perl to compile the kernel, but it can be easily patched out. You will need to apply the following patch. Patch was written by @uref{https://github.com/E5ten, E5ten}. You will need to obtain and apply the patch in the kernel source directory. @example wget https://dl.carbslinux.org/distfiles/kernel-no-perl.patch patch -p1 < kernel-no-perl.patch @end example @node Building the kernel @subsection Building the kernel Next step is configuring and building the kernel. You can check Gentoo's @uref{https://wiki.gentoo.org/wiki/Kernel/Configuration, kernel configuration guide} to learn more about the matter. Overall, Gentoo Wiki is a good place to learn about configuration according to your hardware. The following will assume a monolithic kernel. @example make menuconfig make install -Dm755 $(make -s image_name) /boot/vmlinuz-linux @end example @node Making your system bootable @section Making your system bootable In order to be able to boot your fresh system, wou will need an init-daemon, init-scripts and a bootloader. The init daemon is already provided by busybox, but you can optionally change it. @menu * Bootloader:: Install a bootloader for your system * Init scripts:: Install init scripts for your system * Fstab:: Generating fstab @end menu @node Bootloader @subsection Bootloader In the main repository, there is efibootmgr and grub to serve as bootloaders. efibootmgr can be used as a standalone bootloader, or can be used to install grub in a UEFI environment. efibootmgr is needed unless you are using a device without UEFI support (or you really want to use BIOS for a reason). @enumerate @item @anchor{GRUB BIOS installation}GRUB BIOS installation @example cpt b grub && cpt i grub grub-install --target=i386-pc /dev/sdX grub-mkconfig -o /boot/grub/grub.cfg @end example @item @anchor{GRUB UEFI installation}GRUB UEFI installation @example cpt b efibootmgr && cpt i efibootmgr cpt b grub && cpt i grub grub-install --target=x86_64-efi \ --efi-directory=esp \ --bootloader-id=CarbsLinux grub-mkconfig -o /boot/grub/grub.cfg @end example @end enumerate @node Init scripts @subsection Init scripts Only thing left to do is installing the init-scripts, and now you are almost ready to boot your system! @example cpt b carbs-init && cpt i carbs-init @end example @node Fstab @subsection Fstab You can now manually edit your fstab entry, or you can use the genfstab tool. If you want to use the tool, exit the chroot and run the following: @example wget https://github.com/cemkeylan/genfstab/raw/master/genfstab chmod +x genfstab ./genfstab -U /mnt >> /mnt/etc/fstab @end example @node Post-installation @section Post-installation The base installation is now complete, you can now fine tune your system according to your needs. Rest of these instructions are completely optional. You can check the rest of the documentation to learn more about the system. @menu * IRC:: Joining the IRC channel * KISS repositories:: Acquire kiss repositories @end menu @node IRC @subsection IRC The IRC channel for Carbs Linux is located in @samp{#carbslinux} on @uref{https://libera.chat, libera.chat}. You can install the @samp{catgirl} package from the repository, or use a client of your preference to join. Feel free to ask for help, or have a general chat. @node KISS repositories @subsection KISS repositories There have been recent changes to the @samp{kiss} package manager that breaks compatibility with @samp{cpt}. These changes throw away the entire premise of their "static" packaging system. @samp{cpt} will never implement those changes, so don't expect any KISS package that was changed during or after July 2021 to work with @samp{cpt}. @node Software @chapter Software The distribution aims to package essential and useful software needed in a practical system. If the repository lacks a package that you use, you may also easily package it yourself or request it to be added to the default repositories over on the IRC channel (@samp{#carbslinux} on @uref{https://libera.chat, Libera}). This section goes over the details of some packaged software @menu * Init System:: Configure the init system * Wayland:: Maintaining a Wayland display system @end menu @node Init System @section Init System Carbs Linux init scripts are run by the init daemon (@samp{busybox} by default) on boot and shutdown processes. It also provides its own halting program named shalt. This provides a portable method that doesn't rely on non-POSIX external programs. @menu * Configuring Init:: Ways to configure the init system * Changing Init Program:: Replace the default busybox init with something new @end menu @node Configuring Init @subsection Configuring Init There are three ways you can change the behaviour of the init system. Those are: @itemize @item Kernel Command Line @item @samp{/etc/init/rc.conf} file @item Init Hooks @end itemize @enumerate @item @anchor{Kernel Command Line}Kernel Command Line On GRUB, you can edit the kernel command line parameters, which will be parsed as variables on the init system. Not all of the parameters will be acted upon, but all of them will be set as variables on the init script. For example an example command line, and how it is interpreted. @example BOOT_IMAGE=/boot/vmlinuz root=/dev/sda2 rw loglevel=3 quiet @end example This command line will be parsed to set the following variables: @example BOOT_IMAGE=/boot/vmlinuz root=/dev/sda2 rw=1 loglevel=3 quiet=1 @end example Some of these variables, such as @samp{rw=/=ro}, @samp{loglevel}, and @samp{quiet}, will be used by the init system to change the behaviour of the startup. @item @anchor{@samp{/etc/init/rcconf} file}@samp{/etc/init/rc.conf} file However, the kernel command line isn't the only place to set your boot parameters. You can specify variables here as well, although note that the kernel command line always gets the priority for these variables since they can be set just before boot. @item @anchor{Init Hooks}Init Hooks Init hooks are for custom personal commands that the user may want to add to alter their boot. These can be used to load kernel modules, modify interfaces, and lot more. Those hooks are added to the @samp{/etc/init} directory with the hook name as the suffix. For example, a boot script will be placed as @samp{/etc/init/my-hook.boot}. Currently, there are 4 hooks that the user can use. @table @asis @item early-boot Run after pseudo-filesystems are mounted. @item boot Run before the boot stage is completed. @item pre.shutdown Run first when shutting down. @item umount Run just before filesystems are unmounted. @item post.shutdown Run just before the system is halted. @end table @end enumerate @node Changing Init Program @subsection Changing Init Program By default, Carbs Linux comes preinstalled with @samp{busybox-init}, but this can easily be replaced without any issues. Currently, available init systems are: @itemize @item @samp{sinit} @item @samp{busybox} init @item @samp{runit} @item @samp{shinit} @end itemize This example is for runit, but it will work with all init systems packaged in the distribution repositories. See the @samp{cpt-alternatives(1)} manual page for more details. @example cpt a runit /usr/bin/init cpt a runit /usr/bin/poweroff cpt a runit /usr/bin/reboot @end example @enumerate @item @anchor{Rebooting after changing init}Rebooting after changing init After switching init systems, your running init system may not accept the new poweroff commands. You will need to reboot/poweroff using the running init's utilities for the new utilities to work. These commands are for the init system currently running on your system and not the one you are switching to. @multitable {aaaaaaaaaaaa} {aaaaaaaaaaaaaaaa} @headitem Program @tab Command @item busybox @tab @samp{busybox reboot} @item runit @tab @samp{runit-init 6} @item shinit/sinit @tab @samp{kill -s INT 1} @end multitable @end enumerate @node Wayland @section Wayland Carbs Linux only supports Wayland displays as of January 2023. If your system makes use of the X.org display system, read the section @ref{Switching from Xorg}. Wayland is a modern display server protocol intended as a replacement for Xorg. Wayland has a much simpler architecture compared to X by its careful design and implementation. Users who want to use a Wayland compositor should follow this section. @menu * Enabling the Wayland repository:: Including the wayland repository in your repository path * Switching from Xorg:: Rebuilding system packages for wayland * Installing a Compositor:: Getting wayland ready for your system @end menu @node Enabling the Wayland repository @subsection Enabling the Wayland repository The @samp{wayland} repository requires packages from @samp{xorg} and @samp{extra} repositories. So you should set your @samp{$CPT_PATH} so that @samp{core} and @samp{extra} repositories precede the @samp{wayland} repository, and the @samp{xorg} repository should come after @samp{wayland}. Here is an example below, where @samp{$REPOSITORY} points to the root of your repository. @example CPT_PATH=$REPOSITORY/core CPT_PATH=$CPT_PATH:$REPOSITORY/extra CPT_PATH=$CPT_PATH:$REPOSITORY/wayland export CPT_PATH @end example After you have enabled your repositories, go ahead and install @samp{wayland} and @samp{wayland-protocols} packages. @example cpt-build wayland wayland-protocols @end example @node Switching from Xorg @subsection Switching from Xorg If you are already an Xorg user, you will need to rebuild some packages so that they support @samp{wayland}. If you don't have an @samp{xorg} system, feel free to skip this step. The packages that need a rebuild are: @itemize @item @samp{gtk+3} @item @samp{gtk4} @item @samp{mesa} @item @samp{webkit2gtk} @end itemize For xorg support inside wayland sessions, you need to install the @samp{xwayland} package. @node Installing a Compositor @subsection Installing a Compositor The @samp{wayland} repository currently only contains @samp{sway} as a Wayland compositor, but you can package something else for your own. @example cpt bi sway @end example @node Contribution Guidelines @chapter Contribution Guidelines Thanks for taking your time to contribute!

This means that they are keeping the packages up-to-date, and responding to issues related to the package. @item [@anchor{3020}3020] If a maintainer doesn't follow the above expectation for a duration of up to a month, their packages will be orphaned and can be adopted by a new maintainer. Maintainers can also request that their packages be orphaned. If the orphaned packages aren't adopted by a new maintainer in a period of two weeks, these packages will be dropped from the repository. @item [@anchor{3030}3030] Package submissions and updates should be submitted in the form of patches to the @uref{https://lists.sr.ht/~carbslinux/carbslinux-devel, ~carbslinux/carbslinux-devel} mailing list.

You can easily find the maintainer information by running @code{cpt-maintainer }. @end table @node Sending Patches @section Sending Patches @menu * Git Patches:: * Fossil Patches:: @end menu @node Git Patches @subsection Git Patches There are multiple ways of sending patches with git. Unfortunately, the most popular / official way of doing it requires Perl and some extra Perl libraries that are not packaged in the repository. This section tries to list other options that are just as useful as @samp{git send-email}. @enumerate @item @anchor{@samp{git-send-email} with msmtp}@samp{git-send-email} with msmtp By default, @samp{git-send-email} uses a Perl SMTP client, but without using it this command doesn't actually need extra Perl libraries, only Perl itself. So, if you are okay with using Perl, the easiest option is to install the @samp{msmtp} package, and change your git configuration to match your msmtp settings. To your @samp{~/.gitconfig}, add the following section: @example [sendemail] smtpserver = /usr/bin/msmtp smtpserveroption = -a smtpserveroption = your-account-name @end example @item @anchor{@samp{git-imap-send}}@samp{git-imap-send} The @samp{git imap-send} command reads patches in mbox format, and uploads it to your imap server as drafts. You can then use your preferred email-client to edit and send them. This is the option with no dependencies. Check out the manual page @samp{git-imap-send(1)} for more information on setting up. @end enumerate @node Fossil Patches @subsection Fossil Patches You can create multiple types of "patches" with Fossil. Unlike the common convention in Git, the first two examples here uses uncommitted changes to create a patch (although you could very well create patches of committed changes). The preferred method is by creating a plaintext patch by doing the following: @example fossil diff -i > your-changes.patch @end example You can also create a binary patch: @example fossil patch create your-changes.db @end example If your patchset is complex, and needs to be splitted in multiple check-ins, you can create a Fossil bundle: @example fossil bundle create --from CHECKIN --to CHECKIN2 patchset.bundle @end example After creating the patches, you can simply send them to the mailing list, or upload the patches to the Fossil forum of the relevant repository. @node GNU Free Documentation License @appendix GNU Free Documentation License @center Version 1.3, 3 November 2008 @display Copyright @copyright{} 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc. @uref{http://fsf.org/} Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. @end display @enumerate 0 @item PREAMBLE The purpose of this License is to make a manual, textbook, or other functional and useful document @dfn{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. @item 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. The "publisher" means any person or entity that distributes copies of the Document to the public. 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. @item 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. @item 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. @item 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: @enumerate A @item 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. @item 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. @item State on the Title page the name of the publisher of the Modified Version, as the publisher. @item Preserve all the copyright notices of the Document. @item Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. @item 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. @item Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. @item Include an unaltered copy of this License. @item 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. @item 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. @item 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. @item 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. @item Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. @item Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. @item Preserve any Warranty Disclaimers. @end enumerate 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. @item 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." @item 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. @item 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. @item 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. @item TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License. However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it. @item 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 @uref{http://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. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Document. @item RELICENSING "Massive Multiauthor Collaboration Site" (or "MMC Site") means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A "Massive Multiauthor Collaboration" (or "MMC") contained in the site means any set of copyrightable works thus published on the MMC site. "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization. "Incorporate" means to publish or republish a Document, in whole or in part, as part of another Document. An MMC is "eligible for relicensing" if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008. The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing. @end enumerate @page @anchor{ADDENDUM How to use this License for your documents} @appendixsec 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: @example 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 1.3 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''. @end example If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with@dots{}Texts."@tie{}line with this: @example with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. @end example 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. @bye
