#  plugins are distributed under the GPL (see COPYING.GPL).  The documentation

#  FLAC distribution contains at the top the terms under which it may be
#  distributed.

#  Since this particular file is relevant to all components of FLAC,

#  restrictive of those mentioned above.  See the file COPYING.Xiph in this
