 Choose the appropriate `--with-*` options:
 
 - `--with-alsa` for the ALSA audio back end. This is required.
-- `--with-avahi` or `--with-tinysvcmdns` for mdns support. Avahi is a widely-used system-wide zero-configuration networking (zeroconf) service -- it may already be in your system. If you don't have Avahi, or similar, then consider including tinysvcmdns, which is a tiny zeroconf service embedded inside the shairport-sync application itself. You should not have more than one zeroconf service on the same system -- bad things may happen, according to RFC 6762. Avahi is recommended.

 - `--with-piddir` for specifying where the PID file should be stored. This directory is normally chosen automatically. The directory must be writable. If you use this option, you may have to edit the init script to search for the PID file in your new location.
