I am looking for a command line parser for Qt4.
I did a small google search, and found this: http://www.froglogic.com/pg?id=PublicationsFreeware&category=getopt however it lacks support for "--enable-foo" and "--disable-foo" switches. Besides that, it looks like a real winner.
EDIT:
It seems Frologic removed this. So the best options I see are using Boost (which is not API nor ABI stable) or forking the support for kdelibs. Yay...
Since Qt 5.2 you can finally find a solution in QtCore itself: I contributed QCommandLineParser there.
