GraphViz::Makefile is a Perl module to create Makefile graphs using GraphViz.
my $gm = GraphViz::Makefile->new(undef, "Makefile");
open(O, ">makefile.ps") or die $!;
new($graphviz, $makefile, $prefix, %args)
Create a GraphViz::Makefile object. The first argument should be a GraphViz object or undef. In the latter case, a new GraphViz object is created by the constructor. The second argument should be a Make object, the filename of a Makefile, or undef. In the latter case, the default Makefile is used. The third argument $prefix is optional and can be used to prepend a prefix to all rule names in the graph output.
Further arguments (specified as key-value pairs):
reversed => 1
Point arrows in the direction of dependencies. If not set, then the arrows point in the direction of "build flow".
Generate the graph, beginning at the named Makefile rule. If $rule is not given, all is used instead.
Return a reference to the GraphViz object. This object can be used for the output methods.
Return a reference to the Make object.
For backward compatibility, the following members in the hash-based GraphViz::Makefile object may be used instead of the methods:
