# This recipe append assumes that all YADRO branches follow the
# <type>/<product>/<description> convention, or are either
# "merge/upstream" or "master" e.g.:
#
# release/nicole/v1
# feature/vesnin/some-feature
# merge/upstream
# master
#
# Release branches (release/<machine>/vX) are expected to be forked off
# the master branch and may contain tags in the form
# <machine>-vX.Y[-rcZ|-dev*]. All release branches without machine tags,
# as well as any non-release branches produce 'Unofficial' builds.
# So do the release branches with -rc or -dev suffix in the latest tag.
