# move binary packages from staging to testing (if possible [1]) and
# additionally all packages specified on the command line from testing
# to the respective stable repository

# 1] Condition for moving a package A from staging to testing is that:
#   a) nothing on the build-list depends on A and
#   b) no done package B which is not being moved depends on A

# TODO:

#  the meta data used to evaluate condition "b" might be for a different
#    version

#  correctly handle if multiple versions of a single package are marked
#    as "done" or "testing"

#  be (even?) more atomic

#  separate locks for staging, testing (and stable)

#  correctly handle if a package moved from community to official or
#    vice versa
