# CAUTION:  Extracting files from Wise installers doesn't really do what
# you expect.  While a Wise installer is a zip file, the zip file
# structure is flat (Wise reconstructs the intended directory structure
# from metadata stored in proprietary FILEnnnn.DAT files also in the
# zip file).  Consequently, the package structure of Python packages is
# lost, and if there's more than one file with the same name, you only
# get "the last one" to be extracted (all files are extracted to the
# same directory).
#
# For Python, this doesn't matter, because we're only sucking out the
# precompiled .pyd and .exe files from the Python installer -- there
# are no name clashes in that set, and it's a pretty safe bet there never
# will be (else Python wouldn't be able to decide which to use!).  We
# use the Python source tarball to get all the non-executable parts we
# need.
#
# pywin32 doesn't have this problem as it now uses
# a standard distutils 'bdist_wininst' installation .exe. These executables are
# valid .zip files with a "PLATLIB" directory being the complete directory
# structure as installed into "site-packages". These recent pywin32 builds have
# no dependencies on registry settings etc so will work directly as copied out of
# the .exe. The only concerns are the pywintypes/pythoncom dlls, which is
# handled by the Inno installer
