NAME
       gvpack - merge and pack disjoint graphs

SYNOPSIS
       gvpack  [  -nguv?  ] [ -mmargin ] [ -array[_flags][n] ] [ -ooutfile ] [
       -Gname=value ] [ files ]

DESCRIPTION
       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.

OPTIONS
       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
              another.

       -array[_flags][n]
              Combines  the  graphs  at  the  graph  level, placing them in an
              array.  By default, the layout is done in row-major  order.  The
              number  of columns used is roughly the square root of the number
              of graphs. If the optional integer n is supplied, this indicates
              the number of columns to use.


       If optional flags are supplied, these consist of an underscore followed
              by any of the letters "c", "t", "b", "l", "r" or "u".  If "c" is
              supplied, the graphs are packed in column-major order, in  which
              case  a  final  integer specifies the number of rows.  The flags
              "t", "b", "l", "r" indicate that components  are  aligned  along
              the  top,  bottom,  left  or  right, respectively.  The "u" flag
              indicates that  the  insertion  order  is  based  on  the  sortv
              attribute attached to each graph.

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

       -mmargin
              Packs the graphs allowing a margin of output points  around  the
              parts.

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

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

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

       -v     Verbose mode.

       -?     Prints usage information and exit.

OPERANDS
       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.

RETURN CODES
       gvpack returns 0 if there were no problems, and non-zero otherwise.

EXAMPLES
       ccomps -x abc.gv | dot | gvpack | neato -s -n2 -Tps
       This pipeline decomposes the graph in abc.gv into its connected  compo-
       nents, lays out each using dot, packs them all together again, and pro-
       duces the final drawing in PostScript. Of course, there is  nothing  to
       prevent one from using different layouts for each component.

BUGS
       All the input graphs must be directed or undirected.

       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.
