afaik, getopt requires that a specified argument accepts an argument or does
not accept an argument (denoted by semi-colon after option letter), but there
is no middle ground.
Ok, after reading `man 3 getopt`, two semi colons can allow an optional
argument, but that is a GNU specific extension, and as such, probably not as
portable as adding a definitive option.
Personally, I don't see the point in having the hardcoded fallback in /temp
(\\Temp), but maybe I missed something.
Hope you have a good christmas btw ;-)
