Have a look at zope.app.rotterdam (deprecated AFAIK) and zope.app.boston.

In this case the '<defaultView>' is used. The root object is just a
Folder - the default view is '@@index.html'. Just put an object
'index.html' into the root folder (or in any folder) to have it
shown by default.

A template is always a whole webpage - mo macro is applied magically.
You have to include macros explicitely:

<div metal:use-macro="context/@@[macro-view]/[macro]">
... my little template...

[macro-view] is the macro-package - e.g. standard_macros or view_macros.
You can define as much as you like by adding templated <page>-zcml
directives for your layer and marking them es macro packages.
(see zope.app.basicskin.standardmacros.StandardMacros.macro_pages)

AFAIK it's just a standard to use "page" to render a view as part of
a management interface and to use "view" to render it standalone.
