# A. Push and upload it if you're satisfied with the state of git and the
# built distributions, or…
#
# B. Rewind the process if you're not (via devel/rewind-release or
# manually).

# If you have GPG and git's user.signingKey option configured, a signed tag
# will be created. Otherwise, an unsigned annotated tag will be used.
#
# The script will prompt you for the new version if you do not provide it as
