It would be GREAT to have a free tool to run design rule checks= on
Gerbers.

Has anyone used the online tool FreeDFM from Advanced Circuits?
<https://www.my4pcb.com/net35/FreeDFMNet/FreeDFMHome.aspx>
It looks like you can upload a zip of your RS-274X Gerbers and
get a DRC report at no cost. =A0I haven't tried it.

Ideally.... it would be REALLY awesome if there were a way to import
Gerbers into pcb -- this would enable both design rule checking
using pcb's engine, and also many other options such as

- panelizing boards given files from other people (non-pcb
=A0users ... what if I wanted to do what Laen AT DorkbotPDX does... can
=A0pcb support it? not now),

- easily importing reference designs from manufacturers (think
=A0RF circuits and other complex designs with tight design
=A0constraints that you don't want to manually recreate or trace by =A0hand,

- porting a board layout from a proprietary tool into pcb.

I know the Gerbers lack a lot of the information that a pcb layout
file provides, but even if the elements (components), vias, etc.
were not automatically made into pcb native entities, it would be a
huge step forward anyway and be 90% of the way there, making a lot
of tasks possible.
