# Build and release a BEAST 3 package.

# Runs `mvn package` to produce the BEAST package ZIP (via maven-assembly-plugin),
# then optionally creates a GitHub release with the ZIP attached.

# Usage:
#   ./release.sh              # build + create package ZIP
#   ./release.sh --release    # also create a GitHub release with the ZIP attached
#
# The ZIP can then be submitted to CBAN (CompEvol/CBAN) by adding an entry
# to packages2.8.xml via pull request. See README.md for details.
