    <p>
      The following paths are the current contents of the load path.  The
      following entries are looked up for Python packages.  Note that not
      all items in this path are folders.  Gray and underlined items are
      entries pointing to invalid resources or used by custom import hooks
      such as the zip importer.
    <p>
      Items with a bright background were expanded for display from a relative
      path.  If you encounter such paths in the output you might want to check
      your setup as relative paths are usually problematic in multithreaded
      environments.
