# Version number of Plugins. For simplicity, based on date when we choose to
# release. We can get more sophisticated later (but then need bump Major >= 2).
# Version number has a Major and Minor version number, git-tags are free to
# append a patchlevel (which is number of commits since last X.Y update).
#
# The CI will automatically tag the release with v${PLLUGIN_VERSION}
#
# TODO: pass as -D to gcc so that modules can provide e.g. --version flags.
