- new import hooks in import.c, exposed in the sys module
- new module called 'zipimport'
- various changes to allow bootstrapping from zip files
I hope I didn't break the Windows build (or anything else for that
matter), but then again, it's been sitting on sf long enough...
Regarding the latest discussions on python-dev: zipimport sets
pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as
/path/to/Archive.zip/subdir/ are supported again.
Python on UNIX now trusts PYTHONHOME unconditionally
Modules/getpath.c:
Landmark changed to os.py.
Setting PYTHONHOME now unconditionally sets sys.prefix
(and sys.exec_prefix). No further checks are done whether the
standard lib can be found in that location or not. This is in
sync with the PC subdir getpath implementations.
PC/getpathp.c:
Landmark changed to os.py.
PC/os2vacpp/getpathp.c:
Landmark changed to os.py.
Note: BAW's checkin on exceptions.c eliminates earlier concerns about
a bogus PYTHONHOME value leading to a core dump. Instead it causes a
useless sys.path and prevents imports.
light of three different situations: (1) running from build; (2)
running from installed; (3) running without being able to find an
installation (e.g. as a COM object). The system paths in the
repository are only used for (3); the path deduced from the
installation location are used otherwise. PYTHONHOME overrides in all
cases.

running out of the build directory. This means that it will no longer
try to use an older version of the library when an older version has
been installed.
- MS_DLL_ID is now set to "1.5" instead of "1.5.x" so Mark Hammond's
extensions won't have to be changed.
- FILEVERSION and PRODUCTVERSION are set to 1,5,2,1.
(The last number could be the build# or the alpha release# or so.)
is now obsolete), and changed the default path calculations.
$PYTHONPATH is now added as a prefix (like it's always been on Unix);
$PYTHONHOME takes precedence over the program pathname; and only one
landmark is needed.
lives to the end of the path.
(Still to do: add $PYTHONPATH to the front instead of using it as is;
add the Win32 registry paths as in getpath_nt.c (which can then
retire).)
