[Zope] modifying objectValues from an external method?

[Randall Kern]

<dtml-call expr="manage_delObjects(ids=objectIds())">

Place this in a DTML method, and it will remove all the sub-objects in the
folder you call it on.

Example:

Create a folder "Test".  In that folder, create a DTML method called
remove_all, and put the DTML from above in it.  Then create another Folder
inside Test called "Lossy".  Create some random stuff you don't mind losing
into this new folder.

Open your browser, and goto http://yourserverhere/Test/Lossy/remove_all

Go back to the manage interface, and notice that all that stuff you didn't
mind losing is gone.
