This will add to the package's __path__ all subdirectories of
directories on sys.path named after the package. This is useful
if one wants to distribute different parts of a single logical
package as multiple directories.
For each directory on sys.path that has a subdirectory that
matches the package name, add the subdirectory to the package's
__path__. This is useful if one wants to distribute different
parts of a single logical package as multiple directories.

It also looks for *.pkg files beginning where * matches the name
argument. This feature is similar to *.pth files (see site.py),
