# 20240312 bkw:
# - update for v3.3.2.
# - use wrapper script rather than symlinks for /usr/bin/* since the
#   symlinks didn't actually work.

# 20240219 bkw: BUILD=3
# - Take over maintenance.
# - Relicense as WTFPL.
# - Fix permission error in package, when $CWD files are not owned by root.
# - Do not install upstream's licenses .xz compressed.
