#  This file is part the FLAC project.  FLAC is comprised of several
#  components distributed under difference 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
