# 20210225 bkw: update for v3.1.0, try using upstream's download
# URL again. Handle bitbucket adding ?rev=<hash> to the filename, by
# using .zip* as the source filename. Not ideal, but workable.

# 20191201 bkw: update for v3.0.2
# 20180829 bkw: update for v3.0.1

# 20180619 bkw:
# - update for v3.0.0
# - host tarball on naptime instead of ponce.cc
# - handle old style or new style zip filename
# - only install exoraw if it exists (was removed in 3.0.0)
# - can still build with VERSION=2.0.9 or VERSION=2.0.10, if needed
