gvmap.sh - pipeline for running gvmap

       Emden R. Gansner <erg@research.att.com>

gvmap.sh  takes  as  input  a  graph  in DOT format, performs a layout, runs the output through gvmap and
       renders the output. At some point, it is hoped to integrate all of these tasks into gvmap.

       The following invocation creates a map with edges in semi-transparent light gray and nodes laid out using
       sfdp:

       gvmap.sh -Ae -Ecolor=#55555522 -Tpng foo.gv > foo.png

       It is equivalent to running the pipeline

       sfdp -Goverlap=prism foo.gv | gvmap -e | neato -n2 -Ecolor=#55555522 -Tpng > foo.png

       The following options are supported:

       -ak   The integer k specifies the average number of artificial points added along the  bounding  box  of
              the  labels.  Such  artificial  points  are  added to avoid a country boundary cutting through the
              boundary box of the labels. Computing time is proportional to k; hence, for large graphs, a  small
              value  of  k is suggested. If k = -1, a suitable value of k is automatically selected based on the
              graph size. By default k = -1.

       -Klayout
              specifies which program should be use for the initial layout. By default, sfdp  is  run.  Also  by
              default, the layout is passed the flag -Goverlap=prism. This can be overridden using a -g flag.

       -Tformat
              specifies  the final output format. This works the same way as the -T flag for any Graphviz layout
              program.

       -Nattr=val
              specifies the setting of a default node attribute during the rendering phase. This works the  same
              way as the -N flag for any Graphviz layout program.

       -Gattr=val
              specifies  the setting of a graph attribute during the rendering phase. This works the same way as
              the -G flag for any Graphviz layout program.

       -Eattr=val
              specifies the setting of a default edge attribute during the rendering phase. This works the  same
              way as the -E flag for any Graphviz layout program.

       -nattr=val
              specifies the setting of a default node attribute during the layout phase. This works the same way
              as the -N flag for any Graphviz layout program.

       -gattr=val
              specifies the setting of a graph attribute during the layout phase. This works the same way as the
              -G flag for any Graphviz layout program.

       -eattr=val
              specifies the setting of a default edge attribute during the layout phase. This works the same way
              as the -E flag for any Graphviz layout program.

       -Aflag
              specifies  a  flag to be passed to gvmap. For example, gvmap.sh -Ae -As3 causes gvmap -e -s3 to be
              run.

       -v     Set verbose mode.

       -V     Print version information and exit.

       -?     Print usage information and exit.
