"""Bundle support.
(See also http://dev.zope.org/Zope3/ThroughTheWebSiteDevelopment .)
A (site-management) bundle is a (site-management) folder with special
status.
Eventually, bundles will be read-only, and the only thing you can do
with bundles is install and uninstall them. At installation time, a
bundle's dependencies and are analized and satisfied, and the
configurations in the bundle are activated, unless they conflict with
existing configurations. This is an interactive process.
XXX This interim code is much less ambitious: it just provides a view
on a (site-management) folder that displays all configurations in a
bundle and lets the user activate them.
