Changes to the library are reflected in real time after the initial scan. The
directories are monitored for changes and rescanned on the fly.
If you place a file with the filename ending .force-rescan in your library,
you can trigger a full rescan of your library. This will clear all music and
playlists from forked-daapd's database and initiate a fresh bulk scan. Pairing
and speaker information will be kept. Only use this for troubleshooting, it is
not necessary during normal operation.
Symlinks are supported and dereferenced. This does interact in tricky ways
with the above monitoring and rescanning, so you've been warned. Changes to
symlinks themselves won't be taken into account, or not the way you'd expect.
