Hi,
	I need to release a firmware to a customer, and he must be allowed
to modify one of the source files (writen in C).
	I don't want to give him the whole code, but I would like to give
him a (unknown format) file + the user modificable routine.
	Anyone can give me a pointer on how to accomplish this?

Regards,

Mauricio Jancic
