    """ZCatalog object

    A ZCatalog contains arbirary index like references to Zope
    objects.  ZCatalog's can index either 'Field' values of object, or
    'Text' values.

    ZCatalog does not store references to the objects themselves, but
    rather to a unique identifier that defines how to get to the
    object.  In Zope, this unique idenfier is the object's relative
    path to the ZCatalog (since two Zope object's cannot have the same
    URL, this is an excellent unique qualifier in Zope).

    Most of the dirty work is done in the _catalog object, which is an
    instance of the Catalog class.  An interesting feature of this
    class is that it is not Zope specific.  You can use it in any
    Python program to catalog objects.
