# 20201103 bkw: update for v0.19
# 20200314 bkw: update for v0.18
# 20191208 bkw: update for v0.17
# 20180904 bkw: update for v0.15

# 20180623 bkw:
# - upstream moved again (to github). use github url for source.
#   the innards of the tarball are slightly different: none of the
#   autoconf-generated stuff is there. however all the actual source
#   code is identical, so I'm not updating BUILD.

# 20171222 bkw:
# - update for v0.14
# - add WTFPL
# - use upstream's homepage URL (they updated it this release)

# 20160725 bkw:
# - update for v0.13
# - removed libpng patch (no longer needed)

# 20150915 bkw:
# - update for v0.12

# Modified 20130620 by B. Watson:
# - Took over maintenance
# - Got rid of static library
# - Use 'make install-strip'
# - Added 'how to edit' stuff to slack-desc
