Drawing Type Hierarchies

A pictorial representation of the type hierarchy often helps tremendously to document a grammar. The functions draw-types and types-postscript create such pictures given the FUF type declarations.

          


DRAW-TYPES (&optional root)
	Produces a character mode picture of the type hierarchy defined in
	FUF.


TYPES-POSTSCRIPT (root filename &key (shrink t))
	Produces a postscript file depicting the type hierarchy defined in
	FUF.  Use root = nil to draw all the types currently defined.
	Root can also be a list of type names, or a single type name.


Example of output:


> (draw-types 'relation)
|- RELATION +
            |- ASCRIPTIVE
            |- POSSESSIVE
            |- LOCATIVE +
                        |- SPATIAL
                        |- TEMPORAL
                        |- ACCOMPANIMENT
                        |- EXISTENTIAL
                        |- NATURAL-PHENOM
