dependencygraph -- generates a library dependency graph for <file>.
This script builds a dot graph of library dependecies. It will then call
Graphviz's dot utility on that file to produce a pdf graph.
$usageln
<option> is
--dot don't generate PDF unless --pdf is specified
--pdf generate a pdf file (default)
--title=<string> use <string> as the title of the graph
--out=<outfile> use <outfile> as name of the output file
--zoom=<dir1>,...,<dirn> zoom into libraries <dir1>,...,<dirn>
--help print this message
--after=<dir> process all libraries after <dir>, exclusive
--before=<dir> process all libraries before <dir>, exclusive
--but=<dir1>,..,<dirn> do not process libraries <dir1>,...,<dirn>
--do=all process all libraries. This is the default,
except when the option --zoom is also specified
--do=<dir1>,..,<dirn> process libraries <dir1>,...,<dirn>
--from=<dir> process all libraries from <dir>, inclusive
--to=<dir> process all libraries to <dir>, inclusive
--top=<topfile> specify name of the top file directory
File <file> is an ordered list of libraries as used by the script provethem.
By default <file> is nasalib.all. If <outfile> is not specified,
<file><postfix> is used. The <postfix> depends on library selection option, i.e.,
--do,--but,--from,--to,--after,--before,--zoom. When the option --zoom is
used in conjunction with one of the other options, the libraries that are selected,
except for those in --zoom, will appear unzoomed in the dependency graph.
except when the option zoom is used.
