Upstream changes:
1.07  Thu Nov  1 12:47:00 2012
	- New maintainer: Ron Savage
	- Pre-emptive apologies for any changes which are not back-compat. No such \ 
problems are expected, but the
		introduction of new methods may disconcert some viewers.
	- Fix RT#78858, reported by Gene Boggs. Audit code for similar problems.
	- Fix RT#79506. reported by Ron Savage.
	- Rename ChangeLog to CHANGES, and add Changelog.ini.
	- Replace all uses of cyclicity_fault() and Carp::croak with die.
	- Remove unused methods: decommission_root(), cyclicity_allowed(), \ 
cyclicity_fault(), inaugurate_root(),
		no_cyclicity() and _update_links(). OK - cyclicity_fault() was called once. It \ 
just died.
	- Add methods: format_node(), hashref2string(), is_root(), node2string(), \ 
tree2string().
		tree2string($opts, $node) - unlike draw_ascii_tree() - can optionally print \ 
the tree starting at any node.
		Override format_node(), hashref2string(), and node2string() if desired.
	- Reformat the POD big-time.
	- Add Build.PL.
	- Re-write Makefile.PL.
	- Remove use vars(@ISA $Debug $VERSION). Replace latter 2 with 'our ...'.
	- Rename t/00_about_verbose.t to t/about.perl.t.
	- Add scripts/cut.and.paste.subtrees.pl. Warning: Some trees get into an \ 
infinite loop.
	- Add t/cut.and.paste.subtrees.t.        Warning: Some trees get into an \ 
infinite loop.
	- Document the options (discouraged by Sean) supported in the call to new($hashref).
