NAME
       VCG tool - visualization of compiler graphs

SYNOPSIS
       vcg [options] [filename]
       xvcg [options] [filename]

SYNOPSIS FOR SEQUENCES OF GRAPH SPECIFICATIONS
       vcg -multi [options] [filename] [options] [filename] ...
       xvcg  -multi [options] [filename] [options] [filename] ...

DESCRIPTION
       The VCG tool reads a VCG specification and visualizes  the
       graph.   If not all positions of nodes are fixed, the tool
       lays the graph out using several  heuristics  as  reducing
       the  number  of  crossings,  minimizing the size of edges,
       centering of nodes.
