-Bindings View: View/Change Script Bindings
-
-    Description
-
-        This view allows you to set "bindings" (associations between a
-        name and a Zope object) in the context of a single Script.
-        These names can be used within the Script to refer to objects
-        outside the script.
-        
-    Controls
-
-        'Context' -- associate a name with the acqusition parent of
-         the script when it is invoked.  The default name for this
-         binding is "context".
-
-        'Container' -- associate a name with the physical parent
-         container of the script when it is invoked.  The default name
-         for this binding is "container".
-
-        'Script' -- associate a name with the script object itself.
-        There is no default name for this binding.
-
-        'Namespace' -- associate a name with the DTML "namespace"
-        object.  When this script is called from DTML, the namespace
-        name will be bound to the DTML namespace object, otherwise it
-        will be bound to an empty namespace.  There is no default name
-        for this binding.
-
-        'Subpath' -- associate a name with the portion of the URL path
-        after the script's name if the script is called directly via a
-        URL.  The subpath is represented as a list of strings split a
-        slash separators if the script is called directly from a URL.
-        Otherwise, the subpath is an empty list.  The default name for
-        this binding is "traverse_subpath".
-
-        'Save Changes' -- saves changes made to the elements of this form.
