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 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.
