+The work would be possible without efforts made by many people build knowledge of GSM. 
+The most important ancestor of *gr-gsm* (and *gsm-receiver* of *Airprobe* project) was *gsm-tvoid*. 
+*Gr-gsm* wouldn't be also possible without help and inspiration by Harald Welte, Dieter Spaar and Sylvain Munaut.
