;    This module provides useful functions to operate with strings.            |
;    But when using these functions, you should always remember, that          |
;    they are capable of overwriting the complete RAM on your device,          |
;    if not used the correct way. This will most likely happen, if a           |
;    string read by one of these functions is not terminated with the          |
;    end of string character ('\0').                                           |
