Hey,
I've created a specification of the new data structure. Well... sort of. Do
you think I'm a troll? I think the list traffic was okay over the weekend.
We've been talking about technical things. DJ and John talk about
mathematical stuff, which is IMHO okay.
I've also used the CR5000. I am inspired by that tool. Most notably, they
also use database as their data storage.
Come, and help us moving PCB! Contribute to the new stuff! If you send me
patches, I'll apply it! But we have to first talk about the the design.
Cheers,
Lev
