Oops, I broke it

Sorry folks, 0.3 is a write-off and won't do concatenation. I've already created a fix in 0.3.0.1 but it appears that Sourceforge is also broken at the moment so I can't upload it. I'll get it up there ASAP. For now use 0.2.2.2 or just wait until 0.3.0.1 is released. 0.2.2.2 is not as cool but it does actually work.
