NAME
       gvmap.sh - pipeline for running gvmap

SYNOPSIS
       gvmap.sh [-vV?]	[ options ] [ -o outfile ] [ files ]

DESCRIPTION
       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.

OPTIONS
       The following options are supported:

       -a k   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 propor-
	      tional 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.

       -K layout
	      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.

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

       -N attr=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.

       -G attr=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.

       -E attr=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.

       -n attr=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.

       -g attr=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.

       -e attr=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.

       -A flag
	      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.

EXAMPLES
       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
