Dependency trees

[Andy Lester]

Is there anything out there that will generate a tree of  
dependencies, probably based on META.yml?

I figure I can pass in Mason, Test::WWW::Mechanize and Catalyst and  
get back a list of dependencies that those require.  It would be the  
entire tree, so like so:

Test::WWW::Mechanize
        Test::Builder
        WWW::Mechanize
                LWP::UserAgent
                        HTTP::Response
                        HTML::Form
                HTML::Tree
                Blah::Blah
        Test::LongString
                Test::Builder
                Blah::Blah

If it doesn't exist, I'll write it.  I just don't want to reinvent  
the wheel.

Thanks,
xoxo,
Andy
