Comment 1 for bug 698829

Proper bus support won't come quickly, however Steve Meier has a fork of libgeda / gnetlist which does support busses. I'm not sure of the exact details of the syntax though.

If you're able, posting an example screen-shot of the kind of bus syntax you're using in the old schematics might give food for thought when this feature is looked at in the future.

I presume by "explosion of pins", you're referring to what would happen if you had to manually route to every wire inside a bus on each symbol.
