Revision history for Perl module GraphViz.

0.14 Thu May  3 17:57:57 BST 2001
	- added support for InterpLit node in RecDescent grammars
	- added cumulative effect for node attributes (patch by Diego
	  Zamboni)
	- changed the quoting rules again to make it easier to read
	  the dot files (idea by Diego Zamboni)
	- make add_edge() automatically add any nodes specified for
	  the edge that have not been previously added to stop the
	  Graph module complaining (patch by Diego Zamboni)
	- new 'node', 'edge', and 'graph' graph attributes to specify
	  global node, edge, and graph attributes (patch by Diego
	  Zamboni)
	- removed t/regex.t and documented that GraphViz::Regex may
	  not work on various perls
	- added GraphViz::Regex_YAPE module, another way to graph
	  a regular expression

0.13 Mon Mar 19 19:31:18 GMT 2001
	- removed 'use warnings' as suggested by David Adler so we
          no longer require Perl 5.6
	- moved all modules into a new 'lib' directory (and updated
	  examples) so that Devel::GraphVizProf gets installed
	- new 'concentrate' graph attribute to merge edges in
	  cluttered directed graphs
	- new 'random_start' graph attribute, which requests an
	  initial random placement for the graph
	- new 'epsilon' graph attribute, which decides how long the
	  graph solver tries before finding a graph layout, requested
	  by Pierre-Yves Genot
	- an empty cluster now means not clustered
	- added GraphViz::Regex and example regexp.pl which visualises
	  a regular expression
	- now an award-winning module!

0.12
	- fixed bug in redcarpet.pl example
	- new rankdir graph attribute, which controls the direction
	  the nodes are linked together (patch by Mark Fowler)
	- new 'width' and 'height' graph attributes control the size
	  of the bounding box of the drawing in inches, requested by
	  Pierre-Yves Genot

0.11 Tue Mar  6 17:37:20 GMT 2001
	- rearranged module naming: Data::GraphViz ->
	  GraphViz::Data::Dumper, Parse::RecDescent::GraphViz ->
	  GraphViz::Parse::RecDescent, XML::GraphViz -> GraphViz::XML,
	- added GraphViz::Remote so that you do not need to install
	  the graphviz tools to use this module

0.10 Mon Mar  5 17:32:14 GMT 2001
	- now allow simple add_edge({$from => $to}) syntax
	  (idea by DJ Adams and Brian Ingerson)
	- much better documentation (especially on attributes)
	- new module Parse::RecDescent::GraphViz (and example) for
	  graphing Parse::RecDescent grammars (idea by Damian Conway)
	- new module XML::GraphViz (and example) for graphing XML
	- new module Data::GraphViz (and example) for graphing data
	  structures
	- new example ppmgraph.pl by Marcel Grunauer which graphs CPAN
	  tarball dependencies using ActiveState's package list (thanks
	  to Brian Ingerson too ;-)
	- new, better, testsuite
	- better quoting (especially in ports) to allow a greater range	
	  of characters
	- new undocumented (it may change) as_graph method, which
	  returns a graph object with the coordinates of nodes and edges

0.09 Fri Jan 12 15:50:17 GMT 2001
	- moved back to "dot" and "neato" from "dotneato"
	- now allow directed and undirected graphs
	- added GraphViz::No and GraphViz::Small subclasses
	  which aid in visualising the structure of large
	  graphs

0.08 Sun Dec  3 15:15:29 GMT 2000
	- minor patch to cope with DESTROY

0.07 Sun Oct  1 15:19:55 2000
	- new features: allows clusters and ports
	- includes the talk I gave on this at yapc::Europe 19100
	- many more examples (well, see the examples directory!),
	  including quite a few PNGs

0.06 Thu Aug 24 09:33:21 2000
	- better quoting of nodes and edges (they can now have 
	really wierd names)
	- new examples directory with xref.pl: "graphing subroutine
	cross-reference reports for Perl modules" and example graph to
	see what kind of things it can do

0.05 Wed Aug 18 13:12:25 2000
	- now use dotneato to layout the graphs and can now ouput in a
	variety of file formats

0.04 Wed Aug  9 16:14:35 2000
	- first released version
