# 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
