# Puts the packages that were just built into the APT and RPM repositories on
# the gh-pages branch, and regenerates the indexes over everything that is
# there.
#
# Old versions are kept rather than replaced. An index built over all of them
# is what lets somebody pin a version or go back to one, and it costs a few
# hundred kilobytes.
#
# Usage: publish-repos.sh <gh-pages checkout> <directory of new packages>
#
# Needs: dpkg-dev, apt-utils, createrepo-c, gpg, and a secret key already
# imported. Its id is taken from the keyring.
