# 2011 Apr 07 - initial release

# 20230911 bkw: update for v0.5.7.
# - switch to MrJoy's fork, which has some minor enhancements.
# - get rid of ssss.1.html: the existing one in our repo is outdated,
#   and the updated one doesn't build properly. it's the same content
#   as the man page, anyway, so redundant.

# 20230709 bkw: BUILD=2
# - new maintainer.
# - man page symlinks to the actual command names.
# - borrow patches from Debian to fix a bug (bad use of memset) and
#   clean up doc.html so it doesn't load an image from paypal.com every
#   time you view it.

# 20230709 bkw: Some patches taken from Debian's ssss-0.5-5. Don't

# rebuild the man page anyway.
