$0: jack not found.

If you want $PRGNAM to be able to make sound, you must install
jack before running this script.

If you want to build a dedicated server, you don't have to install
jack. Instead, export SERVERONLY=yes in the environment. See SERVER.txt
for details.

# "BSD General Commands Manual" unconditionally (no way to force it
