#  This file is part the FLAC project.  FLAC is comprised of several

#  components distributed under different licenses.  The codec libraries

#  are distributed under Xiph.Org's BSD-like license (see the file

#  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

#  distributed.

#

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

#  it may be distributed under the Xiph.Org license, which is the least

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

#  distribution.

# NOTE that for many of the AM_CONDITIONALs we use the prefix FLaC__

# instead of FLAC__ since autoconf triggers off 'AC_' in strings
