Revision history for Perl extension GraphViz2::Marpa::PathUtils.

1.04  Wed Jun 12 08:55:00 2013
	- Install Graphviz 2.30.1 from AT&T.
	- Rename CHANGES to Changes as per CPAN::Changes::Spec.
	- Re-write the code in Build.PL and Makefile.PL which checks for Graphviz (dot) being installed,
		since the previous code, using a pipe, was failing on some versions of Windows.
	- Assume Config.pm is installed, and hence remove it from the pre-reqs.
		This also stops a warning message generated because Config's version # is undef.
	- Likewise assume File::Spec and File::Temp are installed, and 'recent enough'.
		This is because the new code uses these 3 modules before specifying the pre-reqs.
	- Bump the pre-req for Perl from 5.10.0 to 5.14, since we 'use feature qw/unicode_strings/.
	- Re-write the code in Build.PL and Makefile.PL which checks for Perl being 'recent enough',
		since the previous code, using a pre-req of "perl => '5.10.0'" generates a warning message
		when using Makefile.PL (for my current Perl V 5.14.2). Now we analyze $Config{version}.
	- Re-create the demo files. See scripts/generate.demo.sh.

1.03  Mon May 20 11:38:00 2013
	- Add another demo, graphs/directed/arrows.gv as data/08.clusters.in.gv, from Graphviz V 2.29.
	- Remove the special-case label "\N" from data/02.fixed.paths.in.gv. Such an escape sequence causes
		Graphviz to override the node-renumbering logic in find_fixed_length_paths(), which I need to allow
		the same node to appear multiple times in the output graph without Graphviz automatically coalescing
		them into a single node.
	- Add a new FAQ entry (the first in the list) to discuss this issue.
	- Remove some other, redundant, node attributes from data/02.fixed.paths.in.gv, to simplify debugging all this.

1.02  Thu Nov  8 12:38:00 2012
	- No code changes.
	- For pre-reqs such as strict, warnings, etc, which ship with Perl, set the version # to 0.
		Reported as RT#80663 by Father Chrysostomos for Tree::DAG_Node.
	- Remove from TODO things which have been implemented.
	- Add scripts/code.attributes2html.pl to create html/code.attributes.html.
	- Add back data/07.clusters.in.gv now Graphviz bug is fixed in V 2.29.20121107.0545.

1.01  Mon Oct 15 14:20:00 2012
	- Implement find_clusters() which finds mutually-exclusive clusters of nodes.
	- Rename data/* and html/* demo files.
	- Re-write scripts/generate.demo.pl to handle new code and file names.
	- Put the demo generating code into GraphViz2::Marpa::PathUtils::Demo.

1.00  Mon Sep 24 17:35:00 2012
	- Original version
