+%D I finally finished graph support, if only because I could
+%D not stand the idea that Karel Wesseling would revert to
+%D \PiCTeX.

+%D The latest version does things more automatically (and
+%D efficiently when no text processing is needed). For
+%D definitions embedded in your document, you need to
+%D use \type {@} as template character, in external files,
+%D \type {%} is also supported.

+%D Graphics that have \type {begingraph} in them are
+%D recognized as such and force handling of embedded \TEX\
+%D code.

+%D A demo can be run with:
