#Also folded two lines and added more detail to the error message for
#unsupported format character.

resource files with various inheritence rules, parsers, etc.

pythonprefs uses this to create a single uniform interface to all
relevant python preferences.

resulted in full recompilation every time.

"optimize" has replaced "don't print".

preference handling code is in modules pythonprefs and preferences.
This should finally make it easier for someone (Just?) to write a
decent interface to preference setting, and it'll allow setting
initial sys.path and such from ConfigurePython.

Added a couple of splash screens to show what we're doing

metaclasses, and acks.

a shared class variable -- but each instance will attempt to clean it
up entirely ob cleanup).

instance, use inst.__dict__.update(value) instead of a for loop with
setattr() over the value.keys().  This is more consistent (the
pickling doesn't use getattr() either but pickles inst.__dict__) and
avoids problems with instances that have a __setattr__ hook.

But it *is* a semantic change (because the setattr hook is no longer
used).  So beware!

lib-tk and lib-stdwin.  (BTW this was also done in the previous
checkin of (toplevel)/Makefile.in, though not noted in the checkin
message.)

(This is necessary because when imported as test.test_rgbimg, the test
directory is not on sys.path.)

makesetup script.  (Sorry Sjoerd -- I know you proposed this a while
ago and I didn't think it would work then.  I looked again and it
does work.)

it will run as package test, e.g. this will run the test suite:

    import test.regrtest
    test.regrtest.main()

- traceback should go to stdout!
- don't import ni, import t1!
- nicer support for command line options, only if run as __main__

(i.e. when using ni, the old __init__.py semantics prevail!)

dummy entry to sys.modules, marking the absence of a submodule by the
same name.

Thus, if module foo.bar executes the statement "import time",
sys.modules['foo.time'] will be set to None, once the absence of a
module foo.time is confirmed (by looking for it in foo's path).

The next time when foo.bar (or any other submodule of foo) executes
"import time", no I/O is necessary to determine that there is no
module foo.time.

(Justification: It may seem strange to pollute sys.modules.  However,
since we're doing the lookup anyway it's definitely the fastest
solution.  This is the same convention that 'ni' uses and I haven't
heard any complaints.)
