ASDF dependency graph or complexity score

[Robert Goldman]

What kind of dependency graph are you looking to make?  Just the 
systems, or also the individual system components?

And do you want a visible representation of this graph, or just some set 
of data structures?

I assume the former, since you should be able to use the system 
components themselves to get all the dependency links.

If it's the former, the easiest thing might be to use CL-DOT and write 
the necessary methods to create a graph.

You might need to get ASDF to compute the plan for `LOAD-OP` as a way to 
ensure that all the required system definitions are loaded.

With respect to test systems, I have usually found it best to have my 
systems, say "foo", have "foo/test" related systems, delegate the 
`test-op` for "foo" to "foo/test" using `in-order-to`, and then only 
"foo/test" needs to depend on the test library -- "foo" itself doesn't 
need it.
