gml2gv


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 signifi-
       cantly, the conversion is at best approximate. In particular, it is not
       clear  how multiedges are differentiated in GML, so multiedges are cre-
       ated in GV with no user-available key. Also, no  attribute  information
       is lost, in that any GML attributes that aren't converted to GV equiva-
       lents are retained as attributes in the output graph.
