+    That's script gives for you a easy way to write your an *.eml dumps, using a Proxmark 3.
+    It's working for 4 and 7 bytes NXP MIFARE Classic 1K cards.
+    The script has including an injection of UID changig for the Chinese Magic Cards GEN 3.
+    
+    Whith choosen an *.eml file you can do:
+
+    1. Write it to the equals of current card UID.
+    2. Write it to anther card with changable UID.
+    3. Send command to lock UID for the Chinese Magic Cards GEN 3.
+    4. Erease all data at the card and set the FFFFFFFFFFFF keys, and Access Conditions to 78778800.

+---General thinks for the future:
+---Add support another types of dumps: BIN, JSON
+---Maybe it will be not only as `hf-writer`, like a universal dump manager.
+---Add undependence from the operation system. At the moment code not working in Linux.
+---Add more chinesse backdoors RAW commands for UID changing (find RAW for the 4 byte familiar chinese card, from native it soft: http://bit.ly/39VIDsU)
+---Hide system messages when you writing a dumps, replace it to some of like [#####----------] 40%
