# Script to prepare project for release.
#
# 1) Drop -SNAPSHOT from all versions
# 2) Create git patches (diffs of changes)
# 3) Create git bundles (byte exact commit objects)
# 4) Create tarball for distribution.

# RELEASE_TAG=Beryllium-SR1  # Example

# Set release tag as $STREAM, when no release tag is passed
RELEASE_TAG="${RELEASE_TAG:-${STREAM^}}"
# Ensure that the first letter of RELEASE_TAG is uppercase.

# Directory to put git format-patches
PATCH_DIR="$WORKSPACE/archives/patches"
mkdir -p "$PATCH_DIR"

# Get the current submodule commit hashes.
