# the newly created tag and to forward the remote branch to that position
#
# it checks for explicit push destinations, if none are found it pushes back to
# where the branch got merged from. Before pushing it checks if the tag is
# signed.

# posttag = gbp-posttag-push

# Options:
# -d: dry-run
# -u: push upstream branch too, if not on remote already
