ChangeLog for Graph-ReadWrite

2.00	2005-jan-02 neilb
	- made the changes needed to work with version 0.5 of Graph classes
	- patch to Graph::Reader::Dot from Mark Hillebrand.
	- fixed warnings "Using a hash as a reference is deprecated"
	- added support for new Dot attributes to Graph::Reader::Dot
	- node ids are now quoted in Graph::Writer::Dot,
	  which means you can safely have space, ':', '-', and other
	  interesting characters in node ids.

1.06	2002-jul-09 neilb

	Added XML::Parser and XML::Writer as dependencies in Makefile.PL.
	This was prompted by looking at testers.cpan.org, which has
	this distribution as failing.

1.05	2002-mar-20 neilb

	Graph::Writer::VCG - common attributes (label, color, and
	text color) weren't supported on edges.
	Bug and fix reported by Alexandre Cherif.

1.05	2002-jan-20 neilb

	Added a basic test-suite.

	Commented out debugging output in the HTK Writer. Sorry Phil!

1.04	2001-nov-11 neilb

	Added Graph::Reader::Dot, a reader for the Dot format
	contributed by Mark Hillebrand.

	Fixed a bug in Graph::Reader::XML, found by Mark Hillebrand.
	The reader would only cope with a single <attribute> element
	inside each graph, node or edge element.

	Changed contact email address to neil@bowers.com

1.03

	Added reader and writer classes for HTK lattice files.

1.02
	Fixed a bug in the XML writer module - the way it was using
	XML::Writer caused STDOUT to be closed after you've written
	a graph. I consider it a bug in XML::Writer, but I was able
	to change the way Graph::Writer::XML uses that module.

	Basically it just means that we construct a new instance
	of XML::Writer every time we write out a graph. For most
	uses, this won't be a problem, but you'd notice a hit if
	you were creating the writer and then writing a lot of graphs.

	This was noticed by Mike Hayward <hayward@loup.net>

1.01

	Added support for URL attribute on nodes in Dot.

	Added support for almost all attributes understood by VCG.

	Added a rough cut at a Writer class for daVinci:
		Graph::Writer::daVinci

1.00 feb 2001 neilb

	Initial release - has baseclass for Reader and Writer classes.

	Reader and Writer for simple XML format.

	Writers for Dot and VCG formats.
