Grammar issue :P never got the original rationale for how the format was
structured. Not a problem anyway.

Uhm. Stop. Courtyard makes no sense for internal layers. So a better
list would be:

F.Courtyard
B.Courtyard
F.KeepoutZ
B.KeepoutZ
F.Keepout
B.Keepout
Inner#.Keepout

(no idea on how the KeepoutZ would be actually used...)

Or otherwise simply define a number for the height and let sort the
primitives on the layer themselves. Or including the equivalent of the
IDF data (makes sense, especially since now there is a lib for IDF).
Well, that form is more or less an IDF equivalent already...

More or less it's there. Maybe some recognition with the other CAD
systems could pop up other 'obvious' layer tags to standardize.
