GUI inserting those once before shortly after I started using it, but
don't know what triggers it -- presumably something in the "expert" view
(which is, suitably enough, unsuited to experts <wink>).

plain unprivileged User acct:
+ Had to duplicate Wise's Uninstal.wse script, in order to change the line
  at its end that unconditionally tries to write uninstall info under HKLM.
  This is our new file Uninstal.wse, which must be included by python20.wse
  instead of using Wise's version.
+ In every other case we write to HKLM, also write to HKCU instead (we
  were already doing that in *most* places, but not quite all).
+ If the user doesn't have admin privs, the DLLs we usually write to the
  system dir are written to the root of the Python installation instead.
  That's python22.dll, plus the two MSVC runtime DLLs.
+ Added a new component "Register file extensions".  Registering .py etc
  is done under HKEY_CLASSES_ROOT, and that also requires admin privs;
  i.e., AFAICT it's impossible for an unprivileged user to accomplish this.
  In the component selection dialog, if the user doesn't have admin privs
  I gray out this new component so the user knows they aren't getting file
  extensions.
After all that, Python installs, the Start Menu entries are OK, it runs
its test suite to completion, and the uninstaller works too.  Only known
problem so far is that the integration with Win2K's Add/Remove subsystem
isn't quite right yet in this irritating case.

Namely, an exception is raised if the second arg to hasattr() is not a
string or Unicode.

Fix suggested by Michael Hudson: Raise TypeError if attribute name
passed to getattr() is not a string or Unicode.  There is some
unfortunate duplication of code between builtin_getattr() and
PyObject_GetAttr(), but it appears to be unavoidable.

And remove all the extern decls in the middle of .c files.
Apparently, it was excluded from the header file because it is
intended for internal use by the interpreter.  It's still intended for
internal use and documented as such in the header file.

Add test that calls eval with a code object that has free variables.

If the code object has free variables, raise TypeError.

If pyexpat is not available and more than one attempt is made to load
an expat-based xml parser, an empty xml.parser.expat module will be
created.  This empty module will confuse xml.sax.expatreader into
thinking that pyexpat is available.

The ugly fix is to verify that the expat module actually defines the
names that are imported from pyexpat.

Import pyexpat first so that import error occurs when it is not
available.

code on Darwin, since the C library version of that seems to be broken.

under MacOS.)

1. Only .py files were getting installed.
2. Empty CVS directories were getting created.
Both were due to trying to get away with "recursively copy *.py" one-
liner scripting.

Still need to test it in pathological scenarios.

the installation was hiding in a part of the GUI I never saw before.  Add
it.

don't use directly, but the Wise utility scripts we invoke (like
uninstal.wse) sometimes need them.

not in the stuff we inherited from Wise 5.0 -- better safe than sorry.

Got rid of useless "Welcome" screen.
Folded Tcl/Tk into the main Python component.
Bug introduced during upgrade:  Start Menu entries didn't work if
    installation was to a path with an embedded space, because the
    enclosing quotes somehow got dropped on the cmdline args.  Repaired.
Years of wizard-generated code blocks left this script hard to read.
    Added many more comments, blank lines, and rearranged related code
    into related blocks where they had drifted apart.
Added %_PYMAJOR_% and %_PYMINOR_% compiler vrbls, and reworked script
    items to use them as appropriate.  This should slash the amount of
    hand-fiddling needed when version numbers change.  Indeed, in the
    body of the script, only the first line should need changing now.
Deleted unreferenced wizard-generated compiler vrbls.
