# Originally written by Felix Krueger

# Now maintained by B. Watson <urchlay@slackware.uk>. Original script
# had no license. Modified version licensed under the WTFPL. See
# http://www.wtfpl.net/txt/copying/ for details.

# 20211127 bkw: BUILD=2
# - portaudio support was broken, explicitly disable it and remove
#   from README.
# - add JACK=no in case someone needs it.
# - dynamic slack-desc.

# 20181022 bkw:
# - Take over maintenance.
# - Update for v1.4.24. Incompatible changes, can't build old version.
# - Add PULSE and OSS env vars.
# - If JACK support is built-in, do the realtime stuff.
# - Minor script cleanups.
# - Don't install the install directions in docdir.
