the phase 2 init of the __builtin__ module, so that multiple
interpreters will get the right exceptions.

but annoying memory leak.  This was introduced when PyExc_Exception
was added; the loop above populating the PyExc_StandardError exception
tuple started at index 1 in bltin_exc, but PyExc_Exception was added
at index 0, so PyExc_StandardError was getting inserted in itself!
How else can a tuple include itself?!

Change the loop to start at index 2.

This was a *fun* one! :-)

__module__ string and if found, print <module>.<class>, unless
<module> == "exceptions".

(1) Introduce Exception as the conceptual root class for all exceptions.

(2) Do less work in __init__(), and more in __str__ (store args
unchanged).

"-i" is given.  (Yes, I know, giving in to Marc Lemburg who wanted
this :-)

explanatory message when the manual directories aren't found.
(I have to say I'm surprised that it actually still works!)

(Includes a patch he sent me a few days later.)

- Don't use "from copy_reg import *".

- Use cls.__module__ instead of calling whichobject(cls, cls.__name__);
  also try __module__ in whichmodule(), just in case.

- After calling save_reduce(), add the object to the memo.

whose name is in the current globals' __name__ variable.  If __name__
is not set, ignore this.

different (programs that write programs).  We are dealing with
metaclasses here.  So change the words slightly.

aren't needed and it was a mistake to add them.

is mostly concentrated in a generalized find_module() and the new
load_module().  Added the new module type constants.  Declare that
SEARCH_ERROR and a whole bunch of module-type-specific functions are
obsolete.

load-module() didn't find a built-in or frozen module.  Also got rid
of is_frozen(), which duplicated the functionality of
find_frozen()!=NULL.

Added Help module.
Checked in PythonCore.prj.hqx (which had somehow slipped through until
now)

Implemented balloon help for options dialog.
