* Extensions:

|
|
|
* -v allows setting the version string on the command line.
|
|
|
|
* -{0|1} sets the (currently ignored) hw_ver flag in the header

* 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.

|
|
* -{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
