+# vorbis: file(1) magic for Ogg/Vorbis files
+#
+# From Felix von Leitner <leitner@fefe.de>
+# Extended by Beni Cherniavsky <cben@crosswinds.net>
+# Further extended by Greg Wooledge <greg@wooledge.org>
+#
+# Most (everything but the number of channels and bitrate) is commented
+# out with `##' as it's not interesting to the average user. The most
+# probable things advanced users would want to uncomment are probably
+# the number of comments and the encoder version.
+#
+# FIXME: The first match has been made a search, so that it can skip
+# over prepended ID3 tags. This will work for MIME type detection, but
+# won't work for detecting other properties of the file (they all need
+# to be made relative to the search). In any case, if the file has ID3
+# tags, the ID3 information will be printed, not the Ogg information,
+# so until that's fixed, this doesn't matter.
+# FIXME[2]: Disable the above for now, since search assumes text mode.

+# -- Second vorbis header packet - the comments

+# libVorbis is the only one existing currently, so I detect specifically
