Announcement text: 
----------------------------------------------------------------------
This package is a collection of macros for METAPOST to
make easier to draw finite-state machines, automata,
labeled graphs, etc. Nodes can be either isolated or
arranged into matrices or trees; edges connect pairs
of nodes through arbitrary paths. Some parameters can
be specified to define different shapes for nodes and/or
different styles for the edges.
