   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:

     import os
     version_info_file = "/System/Library/CoreServices/ 
SystemVersion.plist"
     if os.path.isfile(version_info_file):
         import plistlib
         info = plistlib.Plist.fromFile(version_info_file)
         print '%(ProductName)s %(ProductVersion)s' % info
     else:
         uname_os, uname_version = do_the_uname_thing
         print '%s %s' % (uname_os, uname_version)

   Or similar.

     -wsv
