If _xmlrpclib is installed, py2exe will find it if the script uses
xmlrpclib.  I guess that is what the user expects.  If _xmlrpclib is not
installed, py2exe will warn that it is missing (this warning is probably
not very useful, and it seems Bob has supressed this warning in py2app).

The point with win32all (now pywin32) is that most windows users will
have it installed, for good reasons.  py2exe will find it, and include
it if the subprocess module is pulled in - whether _subprocess is
available or not.  But subprocess, the Python 2.4 version, will *never*
use it, because _subprocess is always available (isn't this now even a
builtin module, in python24.dll?).

Hope that answers your question,
