involve a filesystem path.  To that end:

- Changed IOError to EnvironmentError and added a hack which checks
  for arg of len 3.  When constructed with a 3-tuple, the third item
  is the filename and this is squirreled away in the `filename'
  attribute.   However, for in-place unpacking backwards
  compatibility, self.args still only gets the first two items.  Added
  a __str__() which prints the filename if it is given.

- IOError now inherits from EnvironmentError

- New class OSError which also inherits from EnvironmentError and is
  used by the posix module.

OSError.  The EnvironmentError serves primarily as the (common
implementation) base class for IOError and OSError.  OSError is used
by posixmodule.c

Also added tuple definition of EnvironmentError when using string
based exceptions.

New function: PyErr_SetFromErrnoWithFilename(PyObject* char*)

Change the argument name for quote() and quote_plus() to safe (which
matches the implementation).

Add doc for the *new* function urlencode().

Fix the implementation of quote_plus().  (It wouldn't treat '+' in the
original data right.)

Add urlencode(dict) which is handy to create the data for sending a
POST request with urlopen().

with a null movie (giving time to all active movies)
- Made the graphics world parameter to SetMovieGWorld optional.

open MPEG files, etc.

filename may be omitted.

before calling it.  This check was there when the objects were of the
same type *before* coercion, but not if they initially differed but
became the same *after* coercion.

slightly different way to test for the existence of unread.

(which is not very relevant when you're in the debugger :-).

according to an idea by Harri Pasanen (but with different syntax).
This affects the 'break' and 'clear' commands and their help
functions.  Also added a helper method lookupmodule().

Also:

- Try to import readline (important when pdb is used from/as a script).
- Get rid of reference to ancient __privileged__ magic variable.
- Moved all import out of functions to the top.
- When used as a script, check that the script file exists.

onecmd(line) must return the value returned by emptyline() or
default(line).

you need to edit four files in order to add one section to the manual?)

fp.tell() -- that won't work on Windows.

(A patch for rfc822 is still needed for one case where it finds a bad
header line and wants to back up.)

 with LaTeX markup added, and some small rewrites to improve the prose.

to core dump if the first argument did not have a "group" attribute.

not calling self.search(); instead, call self.code.match() directly
and interpret the list of registers it returns directly.  This saves
the overhead of instantiating a MatchObject for each hit, basically
inlining search() as well as group().  When a MatchObject is still
needed, one is allocated and reused for the duration of the scan.

Added test for m.groups() with default.
Added a few prints announcing various tests in verbose mode.

O_getattr():  Added read-only access to the closed attribute, based on comment
	from Michael Scharf <Michael.Scharf@Rhein-Neckar.de>.

before JPython 1.0 came out.)

Sparc Solaris 2.6 (fully patched!) that I don't want to dig into, but
which I suspect is a bug in the multithreaded malloc library that only
shows up when run on a multiprocessor.  (The program wasn't using
threads, it was just using the multithreaded C library.)

In the bbox method of Group (Canvas.py file), you should read

	return self.canvas._getints(self._do('bbox'))

instead of

	return self._getints(self._do('bbox'))

	extensions, and include the "." in ".pyc".  Still need to get
	_tkinter.c:Tkapp_New() to use baseName....

low-level Python exit handler.  This can attempt to call Python code
at a point that the interpreter and thread state have already been
destroyed, causing a Bus Error.  Given the intended use of
Py_AtExit(), I'm not convinced that it's a good idea to call it
earlier during Python's finalization sequence...  (Although this is
the only use for it in the entire distribution.)

can be deleted, but that's good enough for things like a "Windows"
menu with the dynamic list of open windows at the end of the menu.

(which was missing, for some reason).

create the preferences file. This is so that frozen programs don't
interfere with an existing Python installation, or leave turds in the
Preferences folder.
