It accepts an optional``FILE_RULES`` file to describes what elements will be either ignored orbe pointed to a non-default reference type/name. The output is written at ``FILE_OUT``. It is capable of identifying defines, functions, structs, typedefs,enums and enum symbols and create cross-references for all of them.It is also capable of distinguish #define used for specifying a Linuxioctl.
