nixpkgs/modules/services/audio/pulseaudio.nix
Eelco Dolstra e91d882a94 * Converted modules that were still using the old (concrete syntax)
style of declaring Upstart jobs.  While at it, converted them to the
  current NixOS module style and improved some option descriptions.
  Hopefully I didn't break too much :-)
