+# rapicomm: A tiny utility to play with RaspiComm board and SliTaz
+# It can be used to initialize the board from cmdline or at boot time.
+# RaspiComm can also be used to run a testsuite to check the board.
+# Read the official RaspiComm user manual to found the GPIO pins map.
+# the utility is compatibel with Busybox Ash and sould be usable on
+# any GNU/Linux OS.
