- * This is a hacked replacement for the 'addpattern' utility used to
- * create wrt54g .bin firmware files.  It isn't pretty, but it does

- *  -{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
