-----------------
- Import from zipfiles is now supported. The name of a zipfile placed
- on sys.path causes the import statement to look for importable
- Python modules (with .py, pyc and .pyo extensions) and packages
- inside the zipfile. To support this, several new variables have
- been added to the sys module: sys.meta_path, sys.path_hooks, and
- sys.path_importer_cache; these make extending the import statement
- much more convenient than overriding the __import__ built-in
- function. For a description of these, see PEP 302. The zipfile
- import follows the specification (though not the sample
- implementation) of PEP 273. The semantics of __path__ are

- A frame object's f_lineno attribute can now be written to from a
trace function to change which line will execute next. A command to
exploit this from pdb has been added. [SF patch #643835]
