 AutoName: MIFARE Classic Tool
-Description: |-
-    This is a low-level tool for analysing Mifare Classic RFID tags. It is not
-    intended to provide an easy interface for writing URIs to tags but that kind of
-    thing is possible.
-
-    The source code page or website for has full instructions. It should work on
-    most NFC-enabled devices but there are exceptions.
