# The release process works in several phases:
#
#   0. We assume the developer created a 'vX.Y' tag.
#   1. Build the source tarball.
#   2. Update the 'guix' package so that it corresponds to the 'vX.Y' tag.
#   3. Build the binary tarballs for that 'guix' package.
#   4. Update the 'guix' package again.
#   5. Build the installation images.  The images will run 'guix'
#      corresponding to 'vX.Y' + 1 commit, and they will install 'vX.Y'.
#
# This 'release' target takes care of everything and copies the resulting
# files to $(releasedir).
#
# XXX: Depend on 'dist' rather than 'distcheck' to work around the Gettext
# issue described at <https://savannah.gnu.org/bugs/index.php?51027>.
