# 20230511 bkw: update for v1.9.22. upstream split the tools off into
# a separate repo, I modified this script to build them and include them
# in this package (like PV does with vim and ctags).
# 20220614 bkw: update for v1.9.21 and 15.0.
# 20210802 bkw: update for v1.9.19 and -current.
# 20210304 bkw: update for v1.9.17.
# 20201104 bkw: update for v1.9.16.
# 20200118 bkw: renamed from 'jack2' to 'jack'. If you want to see
#               the old log: "git log -- audio/jack2"
# 20200112 bkw: get rid of --profile (thanks, dive!), BUILD=2.
# 20191201 bkw: update for v1.9.14 (including new python3 dep).
# 20180714 bkw:
# - Take over maintenance.
# - Update for v1.9.12.
# - Move HTML docs to proper Slackware doc dir.
# - i486 => i586.

# Minor source of incompatibility between jack 1.x and 2.x: some jack
# apps don't add -lpthread to their CFLAGS because they assume jack.pc
# will already include it (it does, in 1.x). So make 2 act like 1:
