+USAGE:\r
+script run brutesim -r rfid_tag -f facility_code -b base_card_number -c count -t timeout -d direction\r
+option argument description\r
+------ -------- -----------\r
+-r *see below RFID Tag: the RFID tag to emulate\r
+-f 0-999 Facility Code: The facility code (dfx: country id, 14a: type)\r
+-b 0-65535 Base Card Number: base card number to start from\r
+-c 1-65536 Count: number of cards to try\r
+-t .0-99999, pause Timeout: timeout between cards (use the word 'pause' to wait for user input)\r
+-d up, down Direction: direction to move through card numbers\r
+-h Show this\r
+\r
+*SUPPORTED TAGS: pyramid, awid, fdx, jablotron, noralsy, presco, visa2000, 14a, hid\r
+\r
+EXAMPLE: \r
+script run brutesim -r pyramid -f 10 -b 1000 -c 10 -t 1 -d down\r
+(the above example would bruteforce pyramid tags, starting at 10:1000, ending at 10:991, and waiting 1 second between each card)\r
