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.
