ChangeLog for Graph-ReadWrite

	The reader would only cope with a single <attribute> element
	inside each graph, node or edge element.

	Changed contact email address to


	Added reader and writer classes for HTK lattice files.

	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

	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 <>


	Added support for URL attribute on nodes in Dot.
