Importing it typically fails anyway (no TZ variable defined), so this
is no great loss.

Use != instead of <> since <> is documented as "obsolescent".
Use "is" and "is not" when comparing with None or type objects.

The attached patches update the standard library so that all modules
have docstrings beginning with one-line summaries.

A new docstring was added to formatter.  The docstring for os.py
was updated to mention nt, os2, ce in addition to posix, dos, mac.

* imghdr.py: added jpeg recognition
* torgb.py: added jpeg conversion
* tzparse.py: use functions from time instead of calendar
* whatsound.py: add /ufs/guido/biin/sgi to $PATH when calling 'whatsound'

* calendar.py: remove stuff now built in time; some cleanup and
  generalization in the calendar printing
* cmd.py: use __init__.
* tzparse.py: This module is no longer necessary -- use builtin time instead!

* Added whatis command to pdb.py
* new module GET.py (GL definitions from <gl/get.h>)
* rect.py: is_empty takes a rect as argument, not two points.
* Added tests for builtin round() [XXX not yet complete!]
