> inconsistent command line arguments: is it -h or help or –help?
I've said it before and I'll say it again: the error "Option `--help` not understood, did you mean `-help`? Use `-help` to display program options." is one of the most insulting things a program can say to me. `--help` is the lowest common denominator. You have to support it. I don't care what your program has to special case in its parsing, just do it. If I knew your program's preferred syntax, I wouldn't be asking it for help.
