The whole week was quite annoying, but at lof of problems were sold. No, on weekend, I hope I will write one very useful and not very simple pure BASH script for parsing script parameters that could be group to some higher level "groups" of parameters.

An could be as follows:

script -A foo -a bar1 -b bar2 -c bar3 bar4 -B foo2 foo3 -a bar5 -b bar6 -d bar7 bar8

The difference from "normal" optioning is that I will be able to use the same options -a or -b in differenct groups of options -A or -B with absolutely different meaning. Well. This is really quite hard to write in pure BASH. So wish "good luck" to me. :)
