desc =[[\r
This script will generate 'hf mf wrbl' commands for each block to format a Mifare card.\r
\r
Alla datablocks gets 0x00\r
As default the script sets the keys A/B to 0xFFFFFFFFFFFF\r
and the access bytes will become 0x78,0x77,0x88\r
The GDB will become 0x00\r
\r
The script will skip the manufactoring block 0.\r
\r
Arguments:\r
	-h             - this help\r
	-k <key>       - the current six byte key with write access\r
	-n <key>       - the new key that will be written to the card\r
	-a <access>    - the new access bytes that will be written to the card\r
