-Named Templates
-===============
-
-We often want to be able to define view logic and view templates
-independently.  We'd like to be able to change the template used by a
-form without being forced to modify the form.
-
-Named templates provide templates that are registered as named view
-adapters.   To define a named template, use the `NamedTemplateImplementation`
-constructor:
-
-    >>> from zope.app.pagetemplate import ViewPageTemplateFile
-    >>> from zope.formlib.namedtemplate import NamedTemplateImplementation
-    >>> sample = ViewPageTemplateFile('sample.pt')
-    >>> sample = NamedTemplateImplementation(sample)
-
-Let's define a view that uses the named template.  To use a named
-template, use the NamedTemplate constructor, and give a template name:
-
-    >>> from zope.formlib.namedtemplate import NamedTemplate
-    >>> class MyView:
-    ...     def __init__(self, context, request):
-    ...         self.context = context
-    ...         self.request = request
-    ...
-    ...     __call__ = NamedTemplate('sample')
-
-Normally, we'd register a named template for a view interface, to
-allow it to be registered for multiple views.  We'll just register it
-for our view class.
-
-    >>> from zope import component
-    >>> from zope.formlib import interfaces
-    >>> component.provideAdapter(sample, [MyView], name='sample')
-
-Now, with this in place, we should be able to use our view:
-
-    >>> class MyContent:
-    ...     def __init__(self, name):
-    ...         self.name = name
-
-    >>> from zope.publisher.browser import TestRequest
-    >>> print MyView(MyContent('bob'), TestRequest())(x=42)
-    <html><body>
-    Hello bob
-    The URL is http://127.0.0.1
-    The positional arguments were ()
-    The keyword argument x is 42
-    </body></html>
-    <BLANKLINE>
-
-The view type that a named template is to be used for can be supplied
-when the named template is created:
-
-    >>> from zope import interface
-    >>> class MyView:
-    ...     def __init__(self, context, request):
-    ...         self.context = context
-    ...         self.request = request
-    ...
-    ...     __call__ = NamedTemplate('sample2')
-
-    >>> sample = ViewPageTemplateFile('sample.pt')
-    >>> sample = NamedTemplateImplementation(sample, MyView)
-    >>> component.provideAdapter(sample, name='sample2')
-    >>> print MyView(MyContent('bob'), TestRequest())(x=42)
-    <html><body>
-    Hello bob
-    The URL is http://127.0.0.1
-    The positional arguments were ()
-    The keyword argument x is 42
-    </body></html>
