[fpc-devel] A little something I've been working on...

[J. Gareth Moreton]

I'm certainly looking forward to taking a proper gander at it, as I'm 
all for supporting people exploring the internals of development, and if 
it proves to be extremely flexible and useful, you'll get a vote from 
me, but have to see it in action first!
