yarp looked over it. with all due respect, what a piece of crap that is. with that i can't even hope to parse the command line of ssh or rdmd. it loses the original order. it doesn't understand -- which in unix means that options stop here. generally does not obey new unix conventions. defines all sort of useless shit like conflicts that i could care less about. i could write one test expression after parsing thank you very much. but it cannot force the types of its arguments so i must make sure i validate /all/ that shit which is much more voluminous. geez. finally it defines so many types and functions anyone will need a fucking graduate course to use it. no thanks. std.getopt mops the floor with it.
