+Purpose: Lua script to communicate with the Mifare Plus EV1, including personalization (setting the keys) and proximity check. Manually edit the file to add to the commands you can send the card.
+
+Please read the NXP manual before running this script to prevent making irreversible changes. Also note:
+	- The Mifare Plus must start in SL0 for personalization. Card can then be moved to SL1 or SL3.
+	- The keys are hardcoded in the script to "00...". Unless you change this, only use this script for testing purposes.
+	- Make sure you choose your card size correctly (2kB or 4kB).
+
+Small changes can be to made this script to communicate with the Mifare Plus S, X, or SE.
+
+Arguments:
+	-h             : this help
