I think we should drop the CERTIFY as it is superfluous and apparently adds more confusion than it clarifies! Why not settle for: 0 WINDING (CCW|CW|UNKNOWN) This defines the winding of the following polygons and means that the file is "certified", (...) (24 years ago, 11-Nov-99, to lugnet.cad.dev)

(...) 0 WINDING (CW|CCW) as the 'certify statement', rather than 0 CLIPPING ON ? Winding is local. Certification is sort-of local -- only the local file is certified, but the local setting affects whether subfiles (in the same reference branch) are (...) (24 years ago, 15-Nov-99, to lugnet.cad.dev)

Actually, I was thinking of CERTIFY, like a enable of the specific new metacommands. Example: If you have a 0 CERTIFY BFC would mean Enable or take into account the GFC related commands. besides the fact that it certifies that file has beeing (...) (24 years ago, 16-Nov-99, to lugnet.cad.dev)
