# FLAC - Free Lossless Audio Codec
# Copyright (C) 2001,2002,2003,2004,2005,2006,2007,2008,2009 Josh Coalson
#
# 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
