[jsword-devel] Sword drivers - a new way of doing things.

[Troy A. Griffitts]

Hey guys.  This might be a touchy question...

but, wasn't the 2nd thing on the priority list (after getting jsword to 
read a standard sword module install set) to make the class hierchy and 
api, in general, similar to sword?

With this said...  I'm glad Mark is considering a modular approach 
similar to the sword engine.

Just wondering if this was still an eventual goal.

	-Troy.
