Shockingly, it even says that parsing the file is "a better way"
than using gestaltSystemVersion().
It's better for python, anyway, I think, since it doesn't require
access to the Carbon API set. Be sure to handle the case where the
file doesn't exist:
version_info_file = "/System/Library/CoreServices/
info = plistlib.Plist.fromFile(version_info_file)
print '%(ProductName)s %(ProductVersion)s' % info
uname_os, uname_version = do_the_uname_thing
print '%s %s' % (uname_os, uname_version)
