Added my namespace and version.
Enhancement: show the root cause for potential `Could not generate documentation`

While generating docs for a my-app.core a `Could not
 generate documentation` was thrown. The root cause was
  not clear at first. Eventually it tracked down to an
  unreferenced (but needed by the framework I'm using)
  routes.clj not explicitly `:use my-app.xxx` in the `ns`
   declaration.
