> Put differently: Why do you echo variables instead of just using them?
Actually, I don't know :P
I copyied the basic parser from an old script I made when I used cygwin, and I
don't remember why I put those there. Maybe there was a problem with cygwin's
getopt, and that echo solved that. Or maybe it was I misunderstanding the man
page when it said I must 'eval' the output and 'eval $2' was failing :P
Those echos don't do any harm, and as shell builtins they don't waste time
loading to memory. Removing them would be more like cosmetics :)
