                      5: .B Graw
                      6: files are very simple.  There is one primitive per line, each primitive indicated
                      7: by a single character identifier.  All strings are enclosed in quotes.  Definition
                      8: need not preceed use, though in practice graw outputs
                      9: .I ref
                     10: (aka include) primitives first and master definitions are seldom found outside libraries.
