[jsword-devel] Keys and Passages

[Joe Walker]

Hi,

Sorry. I've been very busy. Monster check-in just landed. It's not as 
bug free as I would normally like, but at least you can see where I've 
got to.
I didn't restructure Keys as discussed below. Partly I ran out of time, 
and partly I'm concerned that the change may take focus away from 
getting 1.0 out.

Joe.
