Docs for __init__.py?

[Matthew Cline]

The documentation for __init__.py at python.org seems a little
sparse.  Is there anything that goes into more depth?  Other
than reading the Python source code?

Specifically, does the package name have to corespond to the
name of the directory that __init__.py is in?  Or is there
some way for __init__.py to say "No, *this* is the name for the
package?"

Thanks in advance.
