# 20180628 bkw:
# Looks like upstream development has stalled since 2015. At some point,
# it might make sense to update this build for the last git commit, since
# there were a couple bugfixes and a useful-looking feature added. For
# now, it'll stay at the last release.

# 20180628 bkw:
# - Take over maintenance.
# - Add LICENSE to doc dir, bump BUILD to 3.
# - Support user-supplied config.h (in $CWD).
# - Fix compiler warning about asprintf().
# - Minor script cleanups/simplifications.
