define Package/snapcast/Default/description
  Synchronous audio player - Snapcast

  Snapcast is a multi-room client-server audio player,
  where all clients are time synchronized with the server
  to play perfectly synced audio.
  It's not a standalone player, but an extension that turns
  your existing audio player into a Sonos-like multiroom solution.
  Audio is captured by the server and routed to the connected clients.
  Several players can feed audio to the server in parallel
  and clients can be grouped to play the same audio stream.
  One of the most generic ways to use Snapcast is in conjunction
  with the Music Player Daemon (MPD) or Mopidy.

# The optional-feature menu is shared by both binaries (single source build), so

# PACKAGE_*"): the packages reference them in DEPENDS, and a back-dependency
# here would form a Kconfig recursion.
