+       Changelog:
+       v2.2 - fixed checksum byte calculation for other versions than 0x2019
+              fixed rare problem with padsize
+              updated info to stock firmware 2.00.20
+              fixed typos
+       v2.1 - used "wrt350n.bin" for the created image (closer to stock)
+               added option to create the image in two separate steps (-b / -z)
+       v2.0 - complete re-write
