Each grammar, reduction relation, and metafunction can be
saved in a .ps file (as encapsulated postscript), or can be
turned into a pict.
Picts are more useful for debugging since DrScheme REPL will
show you the pict directly (albeit with slightly different
fonts than you'd see in the .ps file). You can also use the
picts with Slideshow's pict library to build more complex
arrangements of the figures and add other picts. See
Slideshow for details.
If you are only using the picts to experiment in DrScheme's
REPL, be sure your program is in the GUI library, and
contains this header:
@schememod[
scheme/gui
(require texpict/mrpict)
(dc-for-text-size
(make-object bitmap-dc%
(make-object bitmap% 1 1)))
]
Be sure to remove the call to dc-for-text-size before you
generate .ps files, otherwise the font spacing will be wrong
in the .ps file.

@scheme[render-language],
@scheme[render-reduction-relation], and
