[Zope] Missing "how to"s

[Pierre Rougier]

hi all,
I am looking for the documentation of the "multiple selection" type, but
the "how to" does not exist anymore on zope.org..... argh...
Has anyone of u a copy of the documentation?
If it is the case, please send me, or explain me how does it work....

(what I want is a ZClass propertie wich allow to choose an item in a
list, I though multiple-selections were fine for that).

Thanks for your attention.

Pierre
