C MACROS MODULE - cpp.pm
The cpp makes filepp behave in a similar manner to a C preprocessor CPP1. DISCLAIMER: filepp is not meant to be a drop in replacement for a C preprocessor even with this module. I would not recommend using filepp as a C preprocessor unless you fully understand how it differs from a real C preprocessor. The output from filepp with the cpp module will not be the same as a real C preprocessor.
