The standard you are looking for is named EIA-247 and is found at
global.ihs.com
to the hefty price of USD 78.00. It's somewhat hard to find the standard by
using
Google or something, but trying out "gerber file format" and
"RS-274-D" gave
enough leads to start a manual hunt at the standards institutes.
Things to look out for:
EIA-274-D The TIA/EIA standard
ISO 6983 The ISO version (same thing in an ISO wrapper)
Looking at the EIA home page (
http://www.eia.org) is just depressing. A huge
amount of gaudy pictures and policy statements and hard to find facts. Go
directly
to
http://global.ihs.com for a "legal, paid for" copy. At the top left corner
of
the home page is a search thingamabob. Enter "EIA-247" in the "document
number"
field and hit the red "SEARCH" button, and off you go. I am sorry, but I have
no clue about what all this look like in Lynx :)
Perhaps some creative backup of the document somewhere can yield a lower price
tag.
Not that I recommend it, illegal as it may be and all that... ;-)
Good hunt.

Everything I've found seems to point me to Gerber,
yes. But I've yet
to find Gerber documentation anywhere (at least anything detailed
enough to be able to write code to). Surely such a thing must exist
somewhere, but I've had no luck finding it.
