G85 is Excellon.=C2=A0 = Not sure how g-code got into the discussion.

The latest gerbv = supports G85 slots, but doesn't seem to support M15/M16.

Erich pointed out my script to generate slots:

=C2=A0 = https://github.com/hackvana/eagle-plated-slots/

Basically the idea is that if you want plated slots, you put two plated d= rills of a specially chosen diameter at either end of the slot, ie, the dia= meter is a magic value you only use for the slot end holes.=C2=A0 My script= takes pairs of holes with that magic diameter, and turns them into a G85 s= lot.=C2=A0 It relies on the two holes being one after the other in the file= .=C2=A0 That's true for Eagle, and may be true for gEDA.

The script was used to generate these slots (gerbers from Eagle,= open source hardware):

This script is easy to plug into the makefile that many gEDA = users use, so it ends up being more or less invisible.
