gvpack  [ -nguv?  ] [ -mmargin ] [ -ooutfile ] [ -Gname=value ] [ files

       gvpack reads in a stream of graphs, combines the graphs into  a  single
       layout,  and  produces a single graph serving as the union of the input
       graphs. The input graphs must be in dot format, and must have all  nec-
       essary  layout  information. Acceptable input is produced by applying a
       Graphviz layout program, such as dot or neato, with no -T flag.

       By default, the packing is done at the cluster level.  Thus,  parts  of
       one  graph  will not intrude into any top-level clusters or overlap any
       nodes or edges of another.

       The output of gvpack can be used to produce concrete output by applying
       neato -s -n2 with the desired -T flag.

       The following options are supported:

       -g     Combines  the  graphs  at the graph level. This uses more space,
              but prevents parts of one graph from occurring between parts  of

              Specifies  attributes  to be added to the resulting union graph.
              For example, this can be used to specify a graph label.

              Packs the graphs allowing a margin of output points  around  the

       -n     Combines  the  graphs at the node level. Clusters are ignored in
              the packing.

              Prints output to the file output. If not given, gvpack uses std-

       -u     Don't pack the graphs. Just combine them into a single graph.

       -v     Verbose mode.

       -?     Prints usage information and exit.

       The following operand is supported:

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

       An  input graph should not have a label, since this will be used in its
       layout. Since gvpack ignores root graph labels,  resulting  layout  may
       contain some extra space.

       gvpack unsets the bounding box attribute of all non-cluster subgraphs.
