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. ----------------------------------------------------------------------
