-[[http://www.gnu.org/software/guix/][GNU Guix]] (IPA: /ɡiːks/) is a purely functional package manager, and
-associated free software distribution, for the [[http://www.gnu.org/gnu/gnu.html][GNU system]]. In addition
-to standard package management features, Guix supports transactional
-upgrades and roll-backs, unprivileged package management, per-user
-profiles, and garbage collection.
-
-It provides [[http://www.gnu.org/software/guile/][Guile]] Scheme APIs, including a high-level embedded
-domain-specific languages (EDSLs) to describe how packages are to be
-built and composed.
-
-A user-land free software distribution for GNU/Linux comes as part of
-Guix.
-
-Guix is based on the [[http://nixos.org/nix/][Nix]] package manager.
-
-
-* Requirements
-
-GNU Guix currently depends on the following packages:
-
- - [[http://gnu.org/software/guile/][GNU Guile 2.0.x]], version 2.0.7 or later
- - [[http://gnupg.org/][GNU libgcrypt]]
- - optionally [[http://savannah.nongnu.org/projects/guile-json/][Guile-JSON]], for the 'guix import pypi' command
- - optionally [[http://www.gnutls.org][GnuTLS]] compiled with guile support enabled, for HTTPS support
- in the 'guix download' command. Note that 'guix import pypi' requires
- this functionality.
-
-Unless `--disable-daemon' was passed, the following packages are needed:
-
- - [[http://sqlite.org/][SQLite 3]]
- - [[http://www.bzip.org][libbz2]]
- - [[http://gcc.gnu.org][GCC's g++]]
-
-When `--disable-daemon' was passed, you instead need the following:
-
- - [[http://nixos.org/nix/][Nix]]
-
-* Installation
-
-See the manual for the installation instructions, either by running
-
- info -f doc/guix.info "(guix) Installation"
-
-or by checking the [[http://www.gnu.org/software/guix/manual/guix.html#Installation][web copy of the manual]].
-
-For information on installation from a Git checkout, please see the ‘HACKING’
-file.
-
-* Installing Guix from Guix
-
-You can re-build and re-install Guix using a system that already runs Guix.
-To do so:
-
- - Install the dependencies (see 'Requirements' above) and build tools using
- Guix:
-
- guix package --install autoconf automake bzip2 gcc-toolchain gettext \
- guile libgcrypt pkg-config sqlite
-
- - Set the environment variables that Guix recommends you to set during the
- package installation process:
- ACLOCAL_PATH, CPATH, LIBRARY_PATH, PKG_CONFIG_PATH
-
- - Set the PATH environment variable to refer to the profile:
- PATH=$HOME/.guix-profile/bin:$PATH
-
- - Re-run the 'configure' script passing it the option
- '--with-libgcrypt-prefix=$HOME/.guix-profile/', as well as
- '--localstatedir=/somewhere', where '/somewhere' is the 'localstatedir'
- value of the currently installed Guix (failing to do that would lead the
- new Guix to consider the store to be empty!).
-
- - Run "make", "make check", and "make install".
-
-* How It Works
-
-Guix does the high-level preparation of a /derivation/. A derivation is
-the promise of a build; it is stored as a text file under
-=/gnu/store/xxx.drv=. The (guix derivations) module provides the
-`derivation' primitive, as well as higher-level wrappers such as
-`build-expression->derivation'.
-
-Guix does remote procedure calls (RPCs) to the Guix or Nix daemon (the
-=guix-daemon= or =nix-daemon= command), which in turn performs builds
-and accesses to the Nix store on its behalf. The RPCs are implemented
-in the (guix store) module.
-
-* Installing Guix as non-root
-
-The Guix daemon allows software builds to be performed under alternate
-user accounts, which are normally created specifically for this
-purpose. For instance, you may have a pool of accounts in the
-=guixbuild= group, and then you can instruct =guix-daemon= to use them
-like this:
-
- $ guix-daemon --build-users-group=guixbuild
-
-However, unless it is run as root, =guix-daemon= cannot switch users.
-In that case, it falls back to using a setuid-root helper program call
-=nix-setuid-helper=. That program is not setuid-root by default when
-you install it; instead you should run a command along these lines
-(assuming Guix is installed under /usr/local):
-
- # chown root.root /usr/local/libexec/nix-setuid-helper
- # chmod 4755 /usr/local/libexec/nix-setuid-helper

-* Guix & Nix
-
-GNU Guix is based on [[http://nixos.org/nix/][the Nix package manager]]. It implements the same
-package deployment paradigm, and in fact it reuses some of its code.
-Yet, different engineering decisions were made for Guix, as described
-below.
-
-Nix is really two things: a package build tool, implemented by a library
-and daemon, and a special-purpose programming language. GNU Guix relies
-on the former, but uses Scheme as a replacement for the latter.
-
-Using Scheme instead of a specific language allows us to get all the
-features and tooling that come with Guile (compiler, debugger, REPL,
-Unicode, libraries, etc.) And it means that we have a general-purpose
-language, on top of which we can have embedded domain-specific languages
-(EDSLs), such as the one used to define packages. This broadens what
-can be done in package recipes themselves, and what can be done around them.
-
-Technically, Guix makes remote procedure calls to the ‘nix-worker’
-daemon to perform operations on the store. At the lowest level, Nix
-“derivations” represent promises of a build, stored in ‘.drv’ files in
-the store. Guix produces such derivations, which are then interpreted
-by the daemon to perform the build. Thus, Guix derivations can use
-derivations produced by Nix (and vice versa).
-
-With Nix and the [[http://nixos.org/nixpkgs][Nixpkgs]] distribution, package composition happens at
-the Nix language level, but builders are usually written in Bash.
-Conversely, Guix encourages the use of Scheme for both package
-composition and builders. Likewise, the core functionality of Nix is
-written in C++ and Perl; Guix relies on some of the original C++ code,
-but exposes all the API as Scheme.
-
-* Related software
-
- - [[http://nixos.org][Nix, Nixpkgs, and NixOS]], functional package manager and associated
- software distribution, are the inspiration of Guix
- - [[http://www.gnu.org/software/stow/][GNU Stow]] builds around the idea of one directory per prefix, and a
- symlink tree to create user environments
- - [[http://www.pvv.ntnu.no/~arnej/store/storedoc_6.html][STORE]] shares the same idea
- - [[https://live.gnome.org/OSTree/][GNOME's OSTree]] allows bootable system images to be built from a
- specified set of packages
- - The [[http://www.gnu.org/s/gsrc/][GNU Source Release Collection]] (GSRC) is a user-land software
- distribution; unlike Guix, it relies on core tools available on the
- host system
