Numerical arguments are fine but the routine for processing command line 
options should be able to know the difference between "-v 1" and "-v 
something.png". Even if it gives an error for second case. It all goes 
back to a design flaw in processing arguments AFAICT. It looks like you 
are try to break everything up into option/value pairs and you introduce 
the errors there.

I have written command processing stuff with PHP from time to time and 
normally process the arguments as I go through the argv array and not 
try and preprocess the array like you have. You should be able to write 
a routine that will process the arguments in random order (save the 
option/value pairs of course) and do proper error checking.

I think I could probably rewrite it to properly handle error checking 
but it's been along time since I wrote those types of routines in C.

Of course at this point it makes more sense to look at fixing the cvs 
code and not a previous release.
