-设置Guix开发环境的最简单的方式当然是使用Guix！下面这些命令启动一个shell，所有的

-
-@example
-guix environment guix
-@end example
-
-这个命令更多的信息请参考@xref{Invoking guix environment}。额外的依赖可以通过
-@option{--ad-hoc}选项添加：
-
-@example
-guix environment guix --ad-hoc help2man git strace
-@end example
-
-运行 @command{./bootstrap} 以使用Autoconf和Automake生成编译系统的基础框架。如果
-你的得到这样的错误：
-
-@example
-configure.ac:46: error: possibly undefined macro: PKG_CHECK_MODULES
-@end example
-
-@noindent
-它可能意味着Autoconf无法找到由pkg-config提供的@file{pkg.m4}。请确保@file{pkg.m4}
-可用。由Guile提供的@file{guile.m4}宏也类似。假如你的Automake安装在
-@file{/usr/local}，那么它不会从@file{/usr/share}里寻找@file{.m4}文件。这种情况下，
-你必须执行下面这个命令：
-
-@example
-export ACLOCAL_PATH=/usr/share/aclocal
-@end example
-
-参考@xref{Macro Search Path,,, automake, The GNU Automake Manual}.
-
-然后，像正常一样运行@command{./configure}。确保提供
-@code{--localstatedir=@var{directory}}参数，@var{directory}是你当前系统的
-@code{localstatedir}的值。（@pxref{The Store}）
-
-最后，用@code{make check}执行测试（@pxref{Running the Test Suite}）。如果遇到任

-
-折腾Guix的完美配置也是折腾Guile的完美配置@pxref{Using Guile in Emacs,,, guile,

-@url{http://www.gnu.org/software/emacs, Emacs}，以及美妙的
-@url{http://nongnu.org/geiser/, Geiser}。为此，请运行：
-
-@example
-guix package -i emacs guile emacs-geiser
-@end example
-
-Geiser允许在Emacs里进行交互式的、增长式的开发：buffer里的代码补全和执行，获取一
-行的文档（docstrings），上下文敏感的补全，@kbd{M-.}跳转到对象定义，测试代码的
-REPL，及更多（@pxref{Introduction,,, geiser, Geiser User Manual}）。为了方便的
-Guix开发，请确保修改Guile的加载路径（load path）以使其能从你的项目里找到源代码文
-件。

-;; @r{假设Guix项目在 ~/src/guix.}
-(with-eval-after-load 'geiser-guile
-  (add-to-list 'geiser-guile-load-path "~/src/guix"))
-@end lisp
-
-真正编辑代码时别忘了Emacs自带了方便的Scheme模式。而且，一定不要错过
-@url{http://www.emacswiki.org/emacs/ParEdit, Paredit}。它提供了直接操作语法树的
-的功能，例如，用S-表达式替换父节点，为S-表达式添加、删除前后的括号，删除后面的S-

-
-@cindex 软件包, 创建
-这个GNU发行版正在开发的早期阶段，可能缺少一些你喜欢的软件。这个章节介绍你可以怎
-样帮助这个发行版成长。
-
-自由软件通常以@dfn{源代码包}的形式分发，通常是包含完整代码的@file{tar.gz}包。添
-加软件包到这个发行版意味着两件事：添加描述如何编译包的@dfn{配方}和一系列依赖软件，
-以及添加配方之外的@dfn{软件包元数据}，如一段文字描述和证书信息。
-
-在Guix里所有这些信息都包含在@dfn{软件包定义}里。软件包定义提供了软件包的高层视角。
-它们使用Scheme编程语言编写，事实上，对每个软件包我们都定义一个绑定到软件包定义的
-的变量，并且从模块（@pxref{Package Modules}）中导出那个变量。然而，深入的Scheme
-知识@emph{不}是创建软件包的前提条件。若要了解软件包的更多信息，@pxref{Defining
-Packages}。
-
-一旦软件包定义准备好了，并且包存在Guix代码树的一个文件里，你可以用@command{guix
-build} (@pxref{Invoking guix build})命令测试它。假设这个新软件包的名字叫做
-@code{gnew}，你可以在Guix编译树里运行这个命令(@pxref{在安装之前运行Guix})：
-
-@example
-./pre-inst-env guix build gnew --keep-failed
-@end example
-
-使用@code{--keep-failed}参数会保留失败的编译树，这可以使调试编译错误更容易。
-@code{--log-file}也是一个调试时很有用的参数，它可以用来访问编译日志。
-
-如果@command{guix}命令找不到这个软件包，那可能是因为源文件包含语法错误，或者缺少
-导出软件包的@code{define-public}语句。为了查找错误，你可以用Guile导入这个模块以
-了解这个错误的详情：
-
-@example
-./pre-inst-env guile -c '(use-modules (gnu packages gnew))'
-@end example
-
-一旦你的软件包可以正确编译，请给我们发送补丁（@pxref{提交补丁}）。当然，
-如果你需要帮助，我们也会很乐意帮助你。一旦补丁被提交到Guix仓库里，这个新的软件包
-会被自动地在支持的平台上编译@url{http://hydra.gnu.org/jobset/gnu/master, our
-continuous integration system}。
-
-@cindex substituter
-用户可以通过运行@command{guix pull}命令获取最新的软件包定义（@pxref{Invoking
-guix pull}）。当@code{@value{SUBSTITUTE-SERVER}}编译好这些软件包之后，安装这些软
-件包时会自动从服务器（@pxref{Substitutes}）上下载编译好的二进制包。唯一需要人工
-干预的地方是评审和应用代码补丁。

-@cindex 自由软件
-开发GNU操作系统是为了用户拥有计算的自由。GNU是@dfn{自由软件}，这意味着它有
-@url{http://www.gnu.org/philosophy/free-sw.html,四项重要的自由}：运行程序的自由，
-以源代码形式学习和修改程序的自由，原样重新分发副本的自由，和分发修改后的版本的自
-由。GNU发行版里包含的软件包只提供遵守这四项自由的软件。
-
-此外，GNU发行版遵循
-@url{http://www.gnu.org/distros/free-system-distribution-guidelines.html,自由软
-件发行版准则}。这些准则拒绝非自由的固件和对非自由软件的推荐，并讨论解决商标和专
-利的方法。
-
-某些上游的软件包源代码包含一小部分违反上述准则的可选的子集，比如这个子集本身就是
-非自由代码。这时，这些讨厌的代码需要用合适的补丁或者软件包定义（@pxref{Defining
-Packages}）里的@code{origin}里的代码片段移除。这样，@code{guix build --source}就
-可以返回自由的源代码而不是未经修改的上游源代码。
-
-
-@node 软件包命名
-@subsection 软件包命名
-
-@cindex 软件包名字
-一个软件包事实上有两个名字：第一个是@emph{Scheme变量}的名字，即用
-@code{define-public}定义的名字。通过这个名字，软件包可以被Scheme代码找到，如用作
-其它软件包的输入。第二个名字是软件包定义里的@code{name}属性的字符串值。这个名字
-用于软件包管理命令，如：@command{guix package}，@command{guix build}
-
-两个名字通常是相同的，常是上游项目名字转成小写字母并把下划线替换成连字符的结果。
-比如，GNUnet转成@code{gnunet}，SDL_net转成@code{sdl-net}。
-
-我们不给库软件包添加@code{lib}前缀，除非它是项目官方名字的一部分。但是
-@pxref{Python模块}和@ref{Perl模块}有关于Python和Perl语言的特殊规则。
-
-字体软件包的名字处理起来不同，@pxref{字体}.
-
-
-@node 版本号
-@subsection 版本号
-
-@cindex 软件包版本
-我们通常只为每个自由软件的最新版本打包。但是有时候，比如对于版本不兼容的库，需要
-有同一个软件包的两个或更多版本。它们需要使用不同的Scheme变量名。我们为最新的版本
-使用@ref{软件包命名}里规定的名字，旧的版本使用加上后缀的名字，后缀是@code{-}
-和可以区分开版本号的版本号的最小前缀。
-
-软件包定义里的名字对于同一个软件包的所有版本都是相同的，并且不含有版本号。
-
-例如，GTK+的2.24.20和3.9.12两个版本可以这样打包：
-
-@example
-(define-public gtk+
-  (package
-    (name "gtk+")
-    (version "3.9.12")
-    ...))
-(define-public gtk+-2
-  (package
-    (name "gtk+")
-    (version "2.24.20")
-    ...))
-@end example
-如果我们还需要GTK+ 3.8.2，就这样打包
-@example
-(define-public gtk+-3.8
-  (package
-    (name "gtk+")
-    (version "3.8.2")
-    ...))
-@end example
-
-@c See <https://lists.gnu.org/archive/html/guix-devel/2016-01/msg00425.html>,
-@c for a discussion of what follows.
-@cindex 用于版本控制快照的版本号
-有时候，我们为软件包上游的版本控制系统（VCS）的快照而不是正式发布版打包。这是特
-殊情况，因为决定哪个是稳定版的权力应该属于上游开发者。然而，有时候这是必须的。那
-么，我们该如何决定写在@code{version}里的版本号呢？
-
-显然，我们需要让VCS快照的commit ID在版本号中体现出来，但是我们也需要确保版本号单
-调递增，以便@command{guix package --upgrade}决定哪个版本号更新。由于commit ID，
-尤其是Git的commit ID，不是单调递增的，我们添加一个每次升级快照时都手动增长的
-revision数字。最后的版本号字符串看起来是这样：
-
-@example
-2.0.11-3.cabba9e
-  ^    ^    ^
-  |    |    `-- 上游的commit ID
-  |    |
-  |    `--- Guix软件包的revision
-  |
-最新的上游版本号
-@end example
-
-把@code{版本号}里的commit ID截短，比如只取7个数字，是一个好主意。它避免了美学上
-的烦恼（假设美学在这里很重要），以及操作系统限制引起的问题（比如Linux内核的127字
-节）。尽管如此，在@code{origin}里最好使用完整的commit ID，以避免混淆。
-
-@example
-(define my-package
-  (let ((commit "c3f29bc928d5900971f65965feaae59e1272a3f7")
-        (revision "1"))          ;Guix软件包的revision
-    (package
-      (version (git-version "0.9" revision commit))
-      (source (origin
-                (method git-fetch)
-                (uri (git-reference
-                      (url "git://example.org/my-package.git")
-                      (commit commit)))
-                (sha256 (base32 "1mbikn@dots{}"))
-                (file-name (git-file-name name version))))
-      ;; @dots{}
-      )))
-@end example
-
-@node 简介和描述
-@subsection 简介和描述
-
-@cindex 软件包描述
-@cindex 软件包简介
-我们已经看到，GNU@tie{}Guix里的每个软件包都包含一个简介（synopsis）和一个描述
-（description）（@pxref{Defining Packages}）。简介和描述很重要：它们是
-@command{guix package --search}搜索的信息，并且是帮助用户决定一个软件包是否符合
-自己需求的重要信息。因此，打包的人应该关注怎样写它们的内容。
-
-简介必须以大写字母开头，并且不能以句号结尾。它们不能以 ``a'' 或者 ``the'' 等没有
-意义的词开头。例如 ``File-frobbing tool'' 要比 ``A tool that frobs files'' 更好。
-简介需要说明软件包是什么－－如 ``Core GNU utilities (file, text, shell)''，或者
-它的用途－－如 GNU@tie{}grep 的简介是 ``Print lines matching a pattern''。
-
-Keep in mind that the synopsis must be meaningful for a very wide audience.
-For example, ``Manipulate alignments in the SAM format'' might make sense
-for a seasoned bioinformatics researcher, but might be fairly unhelpful or
-even misleading to a non-specialized audience.  It is a good idea to come up
-with a synopsis that gives an idea of the application domain of the
-package.  In this example, this might give something like ``Manipulate
-nucleotide sequence alignments'', which hopefully gives the user a better
-idea of whether this is what they are looking for.
-
-Descriptions should take between five and ten lines.  Use full sentences,
-and avoid using acronyms without first introducing them.  Please avoid
-marketing phrases such as ``world-leading'', ``industrial-strength'', and
-``next-generation'', and avoid superlatives like ``the most
-advanced''---they are not helpful to users looking for a package and may
-even sound suspicious.  Instead, try to be factual, mentioning use cases and
-features.
-
-@cindex Texinfo markup, in package descriptions
-Descriptions can include Texinfo markup, which is useful to introduce
-ornaments such as @code{@@code} or @code{@@dfn}, bullet lists, or hyperlinks
-(@pxref{Overview,,, texinfo, GNU Texinfo}).  However you should be careful
-when using some characters for example @samp{@@} and curly braces which are
-the basic special characters in Texinfo (@pxref{Special Characters,,,
-texinfo, GNU Texinfo}).  User interfaces such as @command{guix package
---show} take care of rendering it appropriately.
-
-Synopses and descriptions are translated by volunteers
-@uref{http://translationproject.org/domain/guix-packages.html, at the
-Translation Project} so that as many users as possible can read them in
-their native language.  User interfaces search them and display them in the
-language specified by the current locale.
-
-To allow @command{xgettext} to extract them as translatable strings,
-synopses and descriptions @emph{must be literal strings}.  This means that
-you cannot use @code{string-append} or @code{format} to construct these
-strings:
-
-@lisp
-(package
-  ;; @dots{}
-  (synopsis "This is translatable")
-  (description (string-append "This is " "*not*" " translatable.")))
-@end lisp
-
-Translation is a lot of work so, as a packager, please pay even more
-attention to your synopses and descriptions as every change may entail
-additional work for translators.  In order to help them, it is possible to
-make recommendations or instructions visible to them by inserting special
-comments like this (@pxref{xgettext Invocation,,, gettext, GNU Gettext}):
-
-@example
-;; TRANSLATORS: "X11 resize-and-rotate" should not be translated.
-(description "ARandR is designed to provide a simple visual front end
-for the X11 resize-and-rotate (RandR) extension. @dots{}")
-@end example

-@node Python模块
-@subsection Python模块
-
-@cindex python
-We currently package Python 2 and Python 3, under the Scheme variable names
-@code{python-2} and @code{python} as explained in @ref{版本号}.  To
-avoid confusion and naming clashes with other programming languages, it
-seems desirable that the name of a package for a Python module contains the
-word @code{python}.
-
-Some modules are compatible with only one version of Python, others with
-both.  If the package Foo compiles only with Python 3, we name it
-@code{python-foo}; if it compiles only with Python 2, we name it
-@code{python2-foo}. If it is compatible with both versions, we create two
-packages with the corresponding names.
-
-If a project already contains the word @code{python}, we drop this; for
-instance, the module python-dateutil is packaged under the names
-@code{python-dateutil} and @code{python2-dateutil}.  If the project name
-starts with @code{py} (e.g.@: @code{pytz}), we keep it and prefix it as
-described above.
-
-@subsubsection Specifying Dependencies
-@cindex inputs, for Python packages
-
-Dependency information for Python packages is usually available in the
-package source tree, with varying degrees of accuracy: in the
-@file{setup.py} file, in @file{requirements.txt}, or in @file{tox.ini}.
-
-Your mission, when writing a recipe for a Python package, is to map these
-dependencies to the appropriate type of ``input'' (@pxref{package Reference,
-inputs}).  Although the @code{pypi} importer normally does a good job
-(@pxref{Invoking guix import}), you may want to check the following check
-list to determine which dependency goes where.
-
-@itemize
-
-@item
-We currently package Python 2 with @code{setuptools} and @code{pip}
-installed like Python 3.4 has per default.  Thus you don't need to specify
-either of these as an input.  @command{guix lint} will warn you if you do.
-
-@item
-Python dependencies required at run time go into @code{propagated-inputs}.
-They are typically defined with the @code{install_requires} keyword in
-@file{setup.py}, or in the @file{requirements.txt} file.
-
-@item
-Python packages required only at build time---e.g., those listed with the
-@code{setup_requires} keyword in @file{setup.py}---or only for
-testing---e.g., those in @code{tests_require}---go into
-@code{native-inputs}.  The rationale is that (1) they do not need to be
-propagated because they are not needed at run time, and (2) in a
-cross-compilation context, it's the ``native'' input that we'd want.
-
-Examples are the @code{pytest}, @code{mock}, and @code{nose} test
-frameworks.  Of course if any of these packages is also required at
-run-time, it needs to go to @code{propagated-inputs}.
-
-@item
-Anything that does not fall in the previous categories goes to
-@code{inputs}, for example programs or C libraries required for building
-Python packages containing C extensions.
-
-@item
-If a Python package has optional dependencies (@code{extras_require}), it is
-up to you to decide whether to add them or not, based on their
-usefulness/overhead ratio (@pxref{提交补丁, @command{guix size}}).

-@subsection Perl模块
-
-@cindex perl
-Perl programs standing for themselves are named as any other package, using
-the lowercase upstream name.  For Perl packages containing a single class,
-we use the lowercase class name, replace all occurrences of @code{::} by
-dashes and prepend the prefix @code{perl-}.  So the class @code{XML::Parser}
-becomes @code{perl-xml-parser}.  Modules containing several classes keep
-their lowercase upstream name and are also prepended by @code{perl-}.  Such
-modules tend to have the word @code{perl} somewhere in their name, which
-gets dropped in favor of the prefix.  For instance, @code{libwww-perl}
-becomes @code{perl-libwww}.

-@cindex java
-Java programs standing for themselves are named as any other package, using
-the lowercase upstream name.
-
-To avoid confusion and naming clashes with other programming languages, it
-is desirable that the name of a package for a Java package is prefixed with
-@code{java-}.  If a project already contains the word @code{java}, we drop
-this; for instance, the package @code{ngsjava} is packaged under the name
-@code{java-ngs}.
-
-For Java packages containing a single class or a small class hierarchy, we
-use the lowercase class name, replace all occurrences of @code{.} by dashes
-and prepend the prefix @code{java-}.  So the class @code{apache.commons.cli}
-becomes package @code{java-apache-commons-cli}.

-
-@cindex fonts
-For fonts that are in general not installed by a user for typesetting
-purposes, or that are distributed as part of a larger software package, we
-rely on the general packaging rules for software; for instance, this applies
-to the fonts delivered as part of the X.Org system or fonts that are part of
-TeX Live.
-
-To make it easier for a user to search for fonts, names for other packages
-containing only fonts are constructed as follows, independently of the
-upstream package name.
-
-The name of a package containing only one font family starts with
-@code{font-}; it is followed by the foundry name and a dash @code{-} if the
-foundry is known, and the font family name, in which spaces are replaced by
-dashes (and as usual, all upper case letters are transformed to lower
-case).  For example, the Gentium font family by SIL is packaged under the
-name @code{font-sil-gentium}.
-
-For a package containing several font families, the name of the collection
-is used in the place of the font family name.  For instance, the Liberation
-fonts consist of three families, Liberation Sans, Liberation Serif and
-Liberation Mono.  These could be packaged separately under the names
-@code{font-liberation-sans} and so on; but as they are distributed together
-under a common name, we prefer to package them together as
-@code{font-liberation}.
-
-In the case where several formats of the same font family or font collection
-are packaged separately, a short form of the format, prepended by a dash, is
-added to the package name.  We use @code{-ttf} for TrueType fonts,
-@code{-otf} for OpenType fonts and @code{-type1} for PostScript Type 1
-fonts.

-In general our code follows the GNU Coding Standards (@pxref{Top,,,
-standards, GNU Coding Standards}).  However, they do not say much about
-Scheme, so here are some additional rules.
-
-@menu
-* Programming Paradigm::     How to compose your elements.
-* Modules::                  Where to store your code?

-
-@node Programming Paradigm
-@subsection Programming Paradigm
-
-Scheme code in Guix is written in a purely functional style.  One exception
-is code that involves input/output, and procedures that implement low-level
-concepts, such as the @code{memoize} procedure.
-
-@node Modules
-@subsection Modules
-
-Guile modules that are meant to be used on the builder side must live in the
-@code{(guix build @dots{})} name space.  They must not refer to other Guix
-or GNU modules.  However, it is OK for a ``host-side'' module to use a
-build-side module.
-
-Modules that deal with the broader GNU system should be in the @code{(gnu
-@dots{})} name space rather than @code{(guix @dots{})}.
-
-@node Data Types and Pattern Matching
-@subsection Data Types and Pattern Matching
-
-The tendency in classical Lisp is to use lists to represent everything, and
-then to browse them ``by hand'' using @code{car}, @code{cdr}, @code{cadr},
-and co.  There are several problems with that style, notably the fact that
-it is hard to read, error-prone, and a hindrance to proper type error
-reports.
-
-Guix code should define appropriate data types (for instance, using
-@code{define-record-type*}) rather than abuse lists.  In addition, it should
-use pattern matching, via Guile’s @code{(ice-9 match)} module, especially
-when matching lists.
-
-@node Formatting Code
-@subsection Formatting Code
-
-@cindex formatting code
-@cindex coding style
-When writing Scheme code, we follow common wisdom among Scheme programmers.
-In general, we follow the @url{http://mumble.net/~campbell/scheme/style.txt,
-Riastradh's Lisp Style Rules}.  This document happens to describe the
-conventions mostly used in Guile’s code too.  It is very thoughtful and well
-written, so please do read it.
-
-Some special forms introduced in Guix, such as the @code{substitute*} macro,
-have special indentation rules.  These are defined in the
-@file{.dir-locals.el} file, which Emacs automatically uses.  Also note that
-Emacs-Guix provides @code{guix-devel-mode} mode that indents and highlights
-Guix code properly (@pxref{Development,,, emacs-guix, The Emacs-Guix
-Reference Manual}).
-
-@cindex indentation, of code
-@cindex formatting, of code
-If you do not use Emacs, please make sure to let your editor knows these
-rules.  To automatically indent a package definition, you can also run:
-
-@example
-./etc/indent-code.el gnu/packages/@var{file}.scm @var{package}
-@end example
-
-@noindent
-This automatically indents the definition of @var{package} in
-@file{gnu/packages/@var{file}.scm} by running Emacs in batch mode.  To
-indent a whole file, omit the second argument:
-
-@example
-./etc/indent-code.el gnu/services/@var{file}.scm
-@end example
-
-@cindex Vim, Scheme code editing
-If you are editing code with Vim, we recommend that you run @code{:set
-autoindent} so that your code is automatically indented as you type.
-Additionally, @uref{https://www.vim.org/scripts/script.php?script_id=3998,
-@code{paredit.vim}} may help you deal with all these parentheses.
-
-We require all top-level procedures to carry a docstring.  This requirement
-can be relaxed for simple private procedures in the @code{(guix build
-@dots{})} name space, though.
-
-Procedures should not have more than four positional parameters.  Use
-keyword parameters for procedures that take more than four parameters.

-@node 提交补丁
-@section 提交补丁
-
-Development is done using the Git distributed version control system.  Thus,
-access to the repository is not strictly necessary.  We welcome
-contributions in the form of patches as produced by @code{git format-patch}
-sent to the @email{guix-patches@@gnu.org} mailing list.
-
-This mailing list is backed by a Debbugs instance accessible at
-@uref{https://bugs.gnu.org/guix-patches}, which allows us to keep track of
-submissions.  Each message sent to that mailing list gets a new tracking
-number assigned; people can then follow up on the submission by sending
-email to @code{@var{NNN}@@debbugs.gnu.org}, where @var{NNN} is the tracking
-number (@pxref{Sending a Patch Series}).
-
-Please write commit logs in the ChangeLog format (@pxref{Change Logs,,,
-standards, GNU Coding Standards}); you can check the commit history for
-examples.
-
-Before submitting a patch that adds or modifies a package definition, please
-run through this check list:
-
-@enumerate
-@item
-If the authors of the packaged software provide a cryptographic signature
-for the release tarball, make an effort to verify the authenticity of the
-archive.  For a detached GPG signature file this would be done with the
-@code{gpg --verify} command.
-
-@item
-Take some time to provide an adequate synopsis and description for the
-package.  @xref{简介和描述}, for some guidelines.
-
-@item
-Run @code{guix lint @var{package}}, where @var{package} is the name of the
-new or modified package, and fix any errors it reports (@pxref{Invoking guix
-lint}).
-
-@item
-Make sure the package builds on your platform, using @code{guix build
-@var{package}}.
-
-@item
-We recommend you also try building the package on other supported
-platforms.  As you may not have access to actual hardware platforms, we
-recommend using the @code{qemu-binfmt-service-type} to emulate them.  In
-order to enable it, add the following service to the list of services in
-your @code{operating-system} configuration:
-
-@example
-(service qemu-binfmt-service-type
- (qemu-binfmt-configuration
-   (platforms (lookup-qemu-platforms "arm" "aarch64" "mips64el"))
-   (guix-support? #t)))
-@end example
-
-Then reconfigure your system.
-
-You can then build packages for different platforms by specifying the
-@code{--system} option.  For example, to build the "hello" package for the
-armhf, aarch64, or mips64 architectures, you would run the following
-commands, respectively:
-@example
-guix build --system=armhf-linux --rounds=2 hello
-guix build --system=aarch64-linux --rounds=2 hello
-guix build --system=mips64el-linux --rounds=2 hello
-@end example
-
-@item
-@cindex bundling
-Make sure the package does not use bundled copies of software already
-available as separate packages.
-
-Sometimes, packages include copies of the source code of their dependencies
-as a convenience for users.  However, as a distribution, we want to make
-sure that such packages end up using the copy we already have in the
-distribution, if there is one.  This improves resource usage (the dependency
-is built and stored only once), and allows the distribution to make
-transverse changes such as applying security updates for a given software
-package in a single place and have them affect the whole system---something
-that bundled copies prevent.
-
-@item
-Take a look at the profile reported by @command{guix size} (@pxref{Invoking
-guix size}).  This will allow you to notice references to other packages
-unwillingly retained.  It may also help determine whether to split the
-package (@pxref{Packages with Multiple Outputs}), and which optional
-dependencies should be used.  In particular, avoid adding @code{texlive} as
-a dependency: because of its extreme size, use @code{texlive-tiny} or
-@code{texlive-union} instead.
-
-@item
-For important changes, check that dependent package (if applicable) are not
-affected by the change; @code{guix refresh --list-dependent @var{package}}
-will help you do that (@pxref{Invoking guix refresh}).

-@cindex branching strategy
-@cindex rebuild scheduling strategy
-Depending on the number of dependent packages and thus the amount of
-rebuilding induced, commits go to different branches, along these lines:
-
-@table @asis
-@item 300 dependent packages or less
-@code{master} branch (non-disruptive changes).
-
-@item between 300 and 1,200 dependent packages
-@code{staging} branch (non-disruptive changes).  This branch is intended to
-be merged in @code{master} every 3 weeks or so.  Topical changes (e.g., an
-update of the GNOME stack) can instead go to a specific branch (say,
-@code{gnome-updates}).
-
-@item more than 1,200 dependent packages
-@code{core-updates} branch (may include major and potentially disruptive
-changes).  This branch is intended to be merged in @code{master} every 2.5
-months or so.
-@end table
-
-All these branches are @uref{https://hydra.gnu.org/project/gnu, tracked by
-our build farm} and merged into @code{master} once everything has been
-successfully built.  This allows us to fix issues before they hit users, and
-to reduce the window during which pre-built binaries are not available.
-
-@c TODO: It would be good with badges on the website that tracks these
-@c branches.  Or maybe even a status page.
-Generally, branches other than @code{master} are considered @emph{frozen} if
-there has been a recent evaluation, or there is a corresponding @code{-next}
-branch.  Please ask on the mailing list or IRC if unsure where to place a
-patch.

-@item
-@cindex determinism, of build processes
-@cindex reproducible builds, checking
-Check whether the package's build process is deterministic.  This typically
-means checking whether an independent build of the package yields the exact
-same result that you obtained, bit for bit.
-
-A simple way to do that is by building the same package several times in a
-row on your machine (@pxref{Invoking guix build}):
-
-@example
-guix build --rounds=2 my-package
-@end example
-
-This is enough to catch a class of common non-determinism issues, such as
-timestamps or randomly-generated output in the build result.
-
-Another option is to use @command{guix challenge} (@pxref{Invoking guix
-challenge}).  You may run it once the package has been committed and built
-by @code{@value{SUBSTITUTE-SERVER}} to check whether it obtains the same
-result as you did.  Better yet: Find another machine that can build it and
-run @command{guix publish}.  Since the remote build machine is likely
-different from yours, this can catch non-determinism issues related to the
-hardware---e.g., use of different instruction set extensions---or to the
-operating system kernel---e.g., reliance on @code{uname} or @file{/proc}
-files.

-When writing documentation, please use gender-neutral wording when referring
-to people, such as @uref{https://en.wikipedia.org/wiki/Singular_they,
-singular ``they''@comma{} ``their''@comma{} ``them''}, and so forth.
-
-@item
-Verify that your patch contains only one set of related changes.  Bundling
-unrelated changes together makes reviewing harder and slower.
-
-Examples of unrelated changes include the addition of several packages, or a
-package update along with fixes to that package.
-
-@item
-Please follow our code formatting rules, possibly running the
-@command{etc/indent-code.el} script to do that automatically for you
-(@pxref{Formatting Code}).
-
-@item
-When possible, use mirrors in the source URL (@pxref{Invoking guix
-download}).  Use reliable URLs, not generated ones.  For instance, GitHub
-archives are not necessarily identical from one generation to the next, so
-in this case it's often better to clone the repository.  Don't use the
-@command{name} field in the URL: it is not very useful and if the name
-changes, the URL will probably be wrong.
