+ * Maps are imported from files named map_XX.h, where XX is the layout code.

+ * Each file declares a char array called map, where the content of each

+ * keys to be parsed when shift or capslock has been pressed.

+ * For example,

+ * associates the key of number 7 to the slash character when shift is pressed.
+ * Yeah, the character associated is a string: this is because of the hashmap

  *
  * By the moment, evspy does not support non-ascii characters.
