# Packaged source files for the first bootstrapping stage.

# We don't have access to utilities such as fetchgit and fetchzip since this
# is this is part of the bootstrap process and would introduce a circular
# dependency. The only tool we have to fetch source trees is `import <nix/fetchurl.nix>`
# with the unpack option, taking a NAR file as input. This requires source
# tarballs to be repackaged.

# To build:
#
# nix-build '<nixpkgs>' -A make-minimal-bootstrap-sources
