# 20240908 bkw:
# - update for v2.3.0b+20240821_dcddc65. this is the latest commit
#   in a fork that's actually maintained (as of Aug 2024), so I'll
#   go with it.
# - apgd actually works in this version, for whatever that's
#   worth. worse than useless IMO, but include it in the package.
# - build with cracklib (so the -k option works).

# I packaged up a post-2.3.0b commit because there are a couple of
# bugfixes and optimizations that came after the release. See commits
# 5135162, 3a0ac14, c23635f.
