# Build a versioned firmware hex and (optionally) commit it into a separate

#
# Usage: build_version.sh [VERSION_TAG]
#   - With VERSION_TAG: checks out that tag, builds, names the hex
#     wii5_buoy_<VERSION_TAG>.hex, also creates wii5_buoy_latest.hex symlink.
#   - Without: builds the current HEAD as a 'dev' build.
