# This program will append a release to the Conectiva Linux package
# repository system.  It's meant to be a startup system to include
# pre-packaged SRPMS in the repository, thus, you should not commit
# packages over an ongoing package structure (with changes in current/
# directory and etc). Also, notice that packages must be included in
# cronological order.
