[Zope] Managing acl_users via scripting

[Dan Shafer]

I can't seem to find any docs on how to manage acl_users folder 
contents programmatically.

For example, can I write a Python script that will add a new user and 
password? How about a script that will change the password of an 
existing acl_user?

Or should I be using exUserFolder (or some other acl_users replacement 
product)?
