gEDA-dev: SoC: Gerber, DRC, gsch2pcb and D-BUS

[Justyn Butler]

Thanks for the responses.

I think now I'll submit two proposals for SoC, which gives gEDA several
weeks to decide which is more crucial for the summer. It's pretty
frustrating because I'd like to work on so many different things.

I'll leave the Gerber converter because it would be implemented as a new,
external program. I have an ulterior motive - I'd like to work on PCB itself
in some way because it will help (force) me to become very familiar with
it's inner workings, so I'll be able to continue coding on it in the future.

My planned proposals:
1) DRC and non-copper layer overhaul.
2) gsch2pcb overhaul including component updating/replacement.

I'll get to work on the formal proposals, and then I'll probably post them
here for some feedback if that's OK.

cheers,
Justyn
