Sure, but it has been many, many years since I last even looked at those tools, so it was faster for me to just use this python script for quick cmdline generation when prototyping things! :-) I wanted something that worked for me, so I'm just sharing it with the community in case others find it useful. If you have time, please do indeed come up with a lex/yacc generator instead, it would indeed be a better solution. [If not, I suggest we take what we can get if it works! :-)] /Bruce
