+You are looking at the suite of software tools developed by the Mother of
+FreeCalypso for calibrating a number of RF parameters on TI-based GSM devices.
+The use of this software absolutely requires highly specialized RF test
+equipment (R&S CMU200 is the only equipment make and model for which support is
+currently implemented) which needs to be connected to the DUT (device under
+test) with an RF coax; all calibration procedures involve the connected external
+test equipment either analyzing the RF signal put out by the DUT or acting as a
+signal generator.  If you don't have the necessary RF test equipment, the
+software alone cannot do anything useful for you.
+
+Because the present software is not intended or usable for end users, a fairly
+advanced level of skill and understanding is expected from the operator.  The
+write-ups in the doc subdirectory provide some guidance, but you are expected
+to study the source code for yourself to fill in the remaining details.
+
+The automated calibration software resides in the autocal and cmu200
+subdirectories; the part in the cmu200 subdir is naturally specific to the R&S
+CMU200, whereas the part in the autocal subdir is agnostic to the specific type
+of RF test equipment as long as it provides the needed functionality.  If you
+wish to use our software with some other type of RF test equipment than CMU200,
+you will need to develop your own replacement for our fc-cmu200d program; you
+should be able to start with the existing fc-cmu200d source and adapt it as
+necessary for your other equipment.
