-=head1 NAME
-
-make_chlayout_test - produce a multichannel test file with the channels
-clearly identified
-
-=head1 SYNOPSIS
-
-tools/make_chlayout_test I<channels> I<out_options>
-
-=head1 DESCRIPTION
-
-This script uses B<ffmpeg> and B<libflite> to produce a file with audio
-channels clearly identified by their name. The resulting file can be used to
-check that the layout and order of channels is correctly handled by a piece
-of software, either a part of B<FFmpeg> or not.
-
-I<channels> is a list of channels or channel layouts, separated by '+'.
-
-I<out_options> is a list of valid ffmpeg outout options, including the
-output file.
-
-Note that some output codecs or formats can not handle arbitrary channel
-layout.
-
-This script requires a B<ffmpeg> binary, either in the source tree or in the
-search path; it must have the flite audio source enabled.
-
-=head1 EXAMPLES
-
-Check that the speakers are correctly plugged:
-
-  tools/make_chlayout_test FL+FR -f alsa default
-
-Produce a 5.1 FLAC file:
-
-  tools/make_chlayout_test 5.1 surround.flac
