I think this needs more clarification as to what is meant by a lib/
root directory. The lib .clj itself is not in this directory, but is
its same-named sibling.
Also, it creates potential overlap between hierarchical namespaces,
e.g. a.b.c and a.b.c.d, where the resources of the former would be
siblings of the root .clj of the latter. Seems confusing at first
glance.
