The ablility to do cool stuff as shown below. You could also
use it to have the same file behave differently on different
machines (with #ifdef's), #include different colors based on the
day of the week, or whatever else you can think of.
from my .xsession:
if [ -x $FVWM2 ]
then
WM=$FVWM2
$FVWM2 -f "FvwmCpp -Cppopt -I${HOME}/include -Cppopt -DHOME=${HOME} -Cppopt -DMYNAME=${SHORT_MACHINE_NAME} .fvwm2rc" > /dev/console 2>&1 &
.
.
.
and in my .fvwm2rc:
/********************************************************************************

#include <X11/mycolors.h>
