#  COPYING.Xiph in this distribution).  All other programs, libraries, and
#  plugins are distributed under the GPL (see COPYING.GPL).  The documentation
#  is distributed under the Gnu FDL (see COPYING.FDL).  Each file in the
#  FLAC distribution contains at the top the terms under which it may be
