Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.

I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.

The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings.  Hope this is
okay.

you do:
    imghdr.what(None, '')
And still go down the

(then f may be None).

* 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'

is moved to the sgi subdirectory.
