# This file evaluates to a function that, when supplied with a system
# identifier, returns the set of all packages provided by the Nix
# Package Collection. It does this by supplying
# `all-packages-generic.nix' with a standard build environment.
#
# On Linux systems, the standard build environment consists of
# Nix-built instances glibc and the `standard' Unix tools, i.e., the
# Posix utilities, the GNU C compiler, and so on. On other systems,
# we use the native C library.

# tools installed on the system outside of the Nix environment,
# i.e., the stuff in /bin, /usr/bin, etc. This environment should
# be used with care, since many Nix packages will not build properly
# with it (e.g., because they require GNU Make).
