 Meizu DFU tool for Linux
 
 This tool can restore the firmware on M3, M6 SP, M6 TP and M6 SL.
+It can also run a single provided file from RAM.
 
 Notes:
 1. SST39VF800.dfu is taken from the official dfu tool provided by Meizu.
 2. updateNAND_BE_070831.dfu is taken from the unofficial dfu tool for M6 SL.
 3. To compile, just run `make'.
