NAME
       gml2gv,gv2gml - GML-DOT converters

SYNOPSIS
       gml2gv [ -?v ] [ -ggname ] [ -ooutfile ] [ files ]
       gv2gml [ -?  ] [ -ooutfile ] [ files ]

DESCRIPTION
       gml2gv  converts  a  graph specified in the GML format to a graph in the GV (formerly DOT)
       format.	gv2gml converts a graph specified in the GV format to a graph in the GML format.

OPTIONS
       The following options are supported:

       -v     Turns on verbose mode

       -?     Prints usage information and exits.

       -ggname
	      The string gname is used as the name of the generated graph.   If  multiple  graphs
	      are generated, subsequent graphs use the name gname appended with an integer.

       -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 speci-
	       fied, 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 particular, 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.

       At present, gv2gml does not support subgraphs and clusters. In addition,  there	does  not
       appear  to be a standard mechanism for specifying default node and edge attributes in GML,
       so any attributes are repeated for every node and edge.
