dirname in sys.path.  This means that you can create a symbolic link
foo in /usr/local/bin pointing to /usr/yourname/src/foo/foo.py, and
then invoking foo will insert /usr/yourname/src/foo in sys.path, not
/usr/local/bin.  This makes it easier to have multifile programs
(before, the program would have to do an os.readlink(sys.argv[0])
itself and insert the resulting directory in sys.path -- Grail does
this).

Note that the expansion is only used for sys.path; sys.argv[0] is
still the original, unadorned filename (/usr/local/bin/foo in the
example).

subdirectories can be made in parallel (unfortunately, Modules has to
depend on all three).

	internal use.  Make sure the maxlevels and level parameters get
	passed to recursive invocations.

	- handles recursive data structures
	- formatting based on a PrettyPrinter object
	- allows a maximum nesting depth to be specified
	- provides safe repr()-like function which does not pretty-print

Removed pprint.py from the README; it's now in the standard lib.

Test it extensively by using pick.

(with some slight formatting changes).

Feature requests:

- Make it a class (everything should be a class);

- support recursive data structures (like pp.py on the ftp contrib site).

Added pformat() function:  formats object to a string representation with
	no trailing newline; returns the string.

contained in commands created by those same widgets.

buffering, so to get the normal behavior back, I set it to
unbuffered.

This used to be done whenever stdin was interactive.  Now we only do
it when the -i flag is given.  Also (and this is the real reason for
this fix) we explicitly allocate a buffer -- this seems to be
necessary on Windows.

string_append().  These must be artifacts of GvR's rewrite.

Fixed some typos in the leading comment (and re-filled the
paragraphs).

Hope you don't mind, Guido.

The function parse_qs currently calls urllib.unquote on the
value of the field submitted, but not on the name.  It needs
to do both.
