# 20180628 bkw: update for v2.7.2.
# 20170218 bkw: make lash optional.

# 20170216 bkw:
# - Updated for v2.7.1. Apparently, upstream released 2.7.1 in 2012, but
#   never got around to updating their web page, which still says that
#   2.5 is the latest release. It took me this long (5 years!) to notice
#   there was a newer version on their sourceforge download page. Note
#   that 2.5 used autotools but 2.7.1 uses cmake, so this script can no
#   longer be used to build the old version.
# - Add capability stuff.
