You think there's going to be much in this? (I'm would assume in the
absence of actual knowledge, maybe the 20% we found on the CLucene
comparison, and probably a bit less.)

Thanks, that's helpful.

The ant target uses gcj to compile from both .java and .class files. It 
also seems to specify particular compiler options which implies that it 
*should* compile out of the box.

I'm keen to have this target working, so I'll hack on the Makefile for a

bit.

B.

p.s. I'm using the latest from HEAD.
