+# This file converts binary firmware files (e.g. extracted
+# from Windows drivers) into a C header file.
+#
+# invocation:
+# fwbin2h <internal fw> <external fw> <radio chipset>
+#
+# which expects the internal and external firmware part in the
+# two files <internal fw> <external fw>.
+# please use: <radio chipset> ::= 503rfmd | i3861 | i3863 | 505rfmd
+# output will be into the file: fw_<radio chipset>_<version>.h
+# where the version is extracted from the internal fw part.
