NAME
       gml2gv - GML-DOT converter

SYNOPSIS
       gml2gv [ -?  ] [ -ooutfile ] [ files ]

DESCRIPTION
       gml2gv converts a graph specified in the GML format to a graph in the GV (formerly DOT) format.

OPTIONS
       The following options are supported:

       -?     Prints usage information and exits.

       -ooutfile
              Prints output to the file outfile. If not given, gml2gv uses stdout.


       OPERANDS
              The following operand is supported:

       files   Names  of files containing 1 or more graphs in GML.  If no files operand is specified, the standard input will be
               used.

RETURN CODES
       Return 0 if there were no problems during conversion; and non-zero if any error occurred.

LIMITATIONS
       As both the graph and graphics models of GV and GML differ significantly, the conversion is at best approximate. In  par-
       ticular, it is not clear how multiedges are differentiated in GML, so multiedges are created in GV with no user-available
       key. Also, no attribute information is lost, in that any GML attributes that  aren't  converted  to  GV  equivalents  are
       retained as attributes in the output graph.
