### PUBLISH

# publish stage is used to push the current master branch of Frama-C and
# associated plugins from the internal frama-c group to the public pub group.
#
# For that, it uses the 'frama-c to frama-c-public' publish key. Thus, to publish
# a new plugin (while keeping its main repository internal), you can add a new
# target to this stage, adapting the script for MetAcsl or Frama-Clang to your
# own plugin.
#
# You must also activate the publish key on both frama-c/my_plugin
# and pub/my_plugin repositories (the former should be read-only, the latter
# must provide write access to the publish key).
# Do not forget to trigger the target only on schedules, so that all public
# repositories stay synchronized.
