+Description: Osmo coding library
+ This is part of the libosmocore "meta"-library. The libosmocore library
+ contains various utility functions that were originally developed as part of
+ the OpenBSC project, but which are of a more generic nature and thus useful to
+ (at least) other programs that are developed in the sphere of Free Software /
+ Open Source mobile communication.
+ .
+ The libosmocoding library in particular contains the implementation of
+ GSM, GPRS and EDGE transcoding routines, migrated from OsmoBTS.
