Maintenance of Tree::DAG_Node
A couple of weeks ago I emailed the author of Tree::DAG_Node,
offering to take over maintenance, to help stop the bitrot.
I've had no response, so if anyone can contact David Hand,
or Sean M. Burke, please do so, so we can discuss this.
Alternately, in a few days I'll get the CPAN maintainers to let
me have co-maint.
