named tuples

[Skaperen]

i'm hoping it will be simple.  but i am getting errors that seem to suggest i am off course.  you guys are acting like you how to do what i want to know how but are assuming i know some critical piece of info that i do not know.

at some point i want to get [ 'major', 'minor', 'micro', 'releaselevel', 'serial ] or something from which i can make that.
