-gsmfr-hand-test		This program was written as part of a debug chase:
-			there seemed to be a design flaw in libgsmfrp, but the
-			actual bug turned out to be in the way we patched
-			osmo-bts-sysmo to produce a continuous RTP stream.
-
-gsmfr-max-out		Another test program written as part of the same debug
-			chase.
-
-gsmfr-preproc		This program reads a gsmx file in FR codec format,
-			passes it through our Rx DTX preprocessor (libgsmfrp),
-			and writes the preprocessor output to another .gsm file.
