# 20240306 xaizek:
# - take over maintenance
# - update for v0.14
# 20230510 bkw: updated for v0.13.
# 20221228 bkw: updated for v0.12.1.
# 20200101 bkw:
# - take over maintenance
# - update for v0.10.1
# - get rid of BETA kludge (handle beta versions more gracefully).
#   script tested with 0.10, 0.10.1-beta, and 0.10.1. I can't be
#   bothered to support older versions (you're on your own).
