[dbdoclet] Re: problems with pdf generation from fo

Well done, Michael, and thank you for turning it around over the weekend!

I've run your revised jar against the simple example that i forwarded to 
you off-list, and it worked first time.

The formatting of some of the synopsis data looked a little odd, but I 
didn't have much time to
investigate it today.  I'll try it on a longer example with some real code 
and see if it recurs.

Other than that, I'm a very happy user now. I love the little class 
diagrams, gives a very professional
look to the generated PDF.
