[Zope] Help! Cascade initialization and acquisition

Hi,

I guess this is a well-known problem and must have
a well-known answer.

I have subfolders inside folders and sub-subfolders
inside subfolders, etc.

I would like to store some initialization actions
in a method called init_dtml inside some of these
folders. (Much like constructors.) Now, when a user
visit the sub-sub-...-subfolder, before displaying
the index_html, I would like to invoke these init_dtml
methods from the top of the folders down to the
sub-sub-...-subfolder.

All this is much like the cascade constructors in
object-oriented programming languages: you invoke
the base class constructor before the subclass
constructor.

The big question is: how do I do this? I have
cracked my head without reaching a simple solution.
Sometimes acquistion is just too evil. :)

(Note that some of the folders may not have init_dtml.)

regards,

Hung Jung
