+
+Occasionally you want to pass software to people who are not (yet!)
+lucky enough to be using Guix.  You'd tell them to run @command{guix
+package -i @var{something}}, but that's not possible in this case.  This
+is where @command{guix pack} comes in.
+
+@cindex pack
+@cindex bundle
+@cindex application bundle
+@cindex software bundle
+The @command{guix pack} command creates a shrink-wrapped @dfn{pack} or
+@dfn{software bundle}: it creates a tarball or some other archive
+containing the binaries of the software you're interested in, and all
+its dependencies.  The resulting archive can be used on any machine that
+does not have Guix, and people can run the exact same binaries as those
+you have with Guix.
+
+For example, to create a bundle containing Guile, Emacs, Geiser, and all
+their dependencies, you can run:
+
+@example
+$ guix pack guile emacs geiser
+@dots{}
+/gnu/store/@dots{}-pack.tar.gz
+@end example
+
+The result here is a tarball containing a @file{/gnu/store} directory
+with all the relevant packages.  The resulting tarball contains a
+@dfn{profile} with the three packages of interest; the profile is the
+same as would be created by @command{guix package -i}.  It is this
+mechanism that is used to create Guix's own standalone binary tarball
+(@pxref{Binary Installation}).
+
+Several command-line options allow you to customize your pack:
+
+@table @code
+@item --system=@var{system}
+@itemx -s @var{system}
+Attempt to build for @var{system}---e.g., @code{i686-linux}---instead of

+
+@item --compression=@var{tool}
+@itemx -C @var{tool}
+Compress the resulting tarball using @var{tool}---one of @code{gzip},
+@code{bzip2}, @code{xz}, or @code{lzip}.

+allow secondary/fallback fonts to provide real glyphs at those codepoints.
+
+The @code{TamzenForPowerline} fonts provide additional @code{Powerline} symbols,
+which are programatically injected with @code{bitmap-font-patcher} and
+later hand-tweaked with the gbdfed(1) editor:
+
+@enumerate
+@item all icons are expanded to occupy the maximum available space
+@item the branch of the fork icon ( U+E0A0) was made larger than the trunk
+@item for the newline icon ( U+E0A1), the @emph{N} was made larger at the bottom
+@item the keyhole in the padlock icon ( U+E0A2) was replaced with @emph{//} lines.
