Another solution (which I'm not endorsing here, just pointing out) is to
use a flag to specify the rules file is local file.


eg non-functional pseudo-code:

if(flag_local->answer)
    strcpy(filename, opt_rules->answer);
else {
    strcpy(filename, "$GISBASE/etc/colors/");
    strcat(filename, opt_rules->answer);
}
fp1 = fopen(filename, "r");



I don't like -l flags as they can be confused with -1 in some fonts.
