I forgot to mention this tool which post processes gerbers= , joining holes of a specified, "magic" diameter, and turning the= m into slots.

I have done this approach for both plated and unplated slots, i.e. drawing lines where the slots will be and also putting a hole/pin at
both ends of that line. Post processing of this is simply exchanging the hole at the beginning of the line with an M15 command, followed by a G01 (with coordinates) command, followed by an M16 at the hole/slot at the
end of the line. Sequence is ended by an M17 and finally M30. For
circular tracks (or arcs) G02 or G03 could probably be used in a similar fashion.

There is a patch for gerbv for adding G00/G01 commands:
ht= tp://sourceforge.net/p/gerbv/patches/56/

I would love to see slots supported by pcb!
