[XFree86] Help with Adding New Option To Driver

[DOLLOFF, MATTHEW D. (MATT) (JSC-ER7) (NASA)]

I am trying to add a new option to xf86Elo.c (elographics_drv.o) so that I can set up the driver to deal with twin view monitors.  I am not sure where I can add the option in the source code so that when the XF86Config file is parsed it recognizes the option as a valid option, and then how I reference that option once I find it.   Thanks, Matt
