It is incredibly simple:

  A Zope object is an instance of some class.
  A class implements a set of interfaces.
  An interface is a set of attributes, i.e. members and methods.

  These interfaces are described in the API.


How to use it:

  if you have an object "o" from class "c" implementing
  interface "i" defining method "m", then you use

	    o.m(... parameters as defined by "i" ...)

  The interface also speaks of constructors. They are
  used to construct (= create) objects.
  They are methods of so called product factories.
  You use them as follows:

      container.manage_addProduct[...product_name...].constructor(
         ... parameters as defined by "i" ...)

  to add an object to "container".
