from the README:

Zieve 0-0-1

Zieve is a (beta) Z-subclassable class that assists in sorting
ZClasses in various ways. To use Zieve... unpack the tgz file in the
zope home folder. Then start Zope and create a ZClass with Zieve as a
base class. Then put an instance of this ZClass where you can reach it
from your folders of other ZClasses. Here is some DTML from a
DTMLMethod that uses a zclass derived from Zieve to do some sorting...

This displays a table heading with links that dynamically resort the
table according to which link was clicked last. The secondary,
tertiary, ...etc keys are remembered from prior clicks....

<!-- 

'theZieve' is an instance of a ZClass that is subclassed from Zieve.
'name', 'color', 'birthsone', 'number' are all properties of the ZClass.
The format  'name:format' allows you to specify a type or filter to
use before comparison.
