@chapter GNU Distribution
Guix comes with a distribution of free software@footnote{The term
``free'' here refers to the
@url{http://www.gnu.org/philosophy/free-sw.html,freedom provided to
users of that software}.} that form the basis of the GNU system. This
includes core GNU packages such as GNU libc, GCC, and Binutils, as well
as many GNU and non-GNU applications. The complete list of available
packages can be seen by running @command{guix-package} (@pxref{Invoking
guix-package}):
@example
guix-package --list-available
@end example
The package definitions of the distribution may are provided by Guile
modules in the @code{(gnu packages ...)} name space---for instance, the
@code{(gnu packages emacs)} module exports a variable named
@code{emacs}, which is bound to a @code{<package>} object
(@pxref{Defining Packages}). The @code{(gnu packages)} module provides
facilities for searching for packages.
The distribution is fully @dfn{bootstrapped} and @dfn{self-contained}:
each package is built based solely on other packages in the
distribution. The root of this dependency graph is a small set of
@dfn{bootstrap binaries}, provided by the @code{(gnu packages
bootstrap)} module. These are statically-linked binaries of the core
tools without which building anything at all would be impossible.
Our goal is to build a practical 100% free software distribution of
Linux-based and other variants of GNU, with a focus on the promotion and
tight integration of GNU components, and an emphasis on programs and
tools that help users exert that freedom.
Building this distribution is a cooperative effort, and you are invited
to join! Please get in touch with us on @email{bug-guix@@gnu.org}. We
welcome ideas, bug reports, patches, and anything that may be helpful to
the project.
