Unfortunately the <fail> task only has an "unless" property in Ant 1.5.
Makes Cactus a bit hard to build. It's possible to emulate that
behaviour with <antcall> statements to targets with "if" conditions.
Btw, I'm halfway through implementing a check-for-valid-properties in
Excalibur. It also recurses through the projects.. kinda neat, hope it
works =)
