+ * This is a hacked replacement for the 'addpattern' utility used to
+ * create wrt54g .bin firmware files. It isn't pretty, but it does
+ * the job for me.
+ *
+ * Extensions:
+ * -v allows setting the version string on the command line.
+ * -{0|1} sets the (currently ignored) hw_ver flag in the header
+ * to 0 or 1 respectively.

+/* January 12, 2005
+ *
+ * Modified by rodent at rodent dot za dot net
+ * Support added for the new WRT54G v2.2 and WRT54GS v1.1 "flags"
+ * Without the flags set to 0x7, the above units will refuse to flash.
+ *
+ * Extensions:
+ * -{0|1|2} sets {0|1} sets hw_ver flag to 0/1. {2} sets hw_ver to 1
+ * and adds the new hardware "flags" for the v2.2/v1.1 units
