DESCRIPTION :
~~~~~~~~~~~
THIS IS AN EXAMPLE OF ACP HEADER FILES
 
  For a given file <HeaderName>.h, all occurences of the string HEADERNAME
  must be replaced with the string <HeaderName>.
  For a given module, all occurences of the string MODULETAG must be replaced
  with the CPA tag of the module (GLI, MTH ...) .
  You must do :
  #define MODULETAG_GLOBALS
  in one (and only one) .c file of your Module.
