--DESCRIPTION--

<p>
    A doctype comes with a set of usual modules to use. Without having
    to mucking about with the doctypes, you can quickly activate or
    disable these modules by specifying which modules you wish to allow
    with this directive. This is most useful for unit testing specific
    modules, although end users may find it useful for their own ends.
</p>
<p>
    If you specify a module that does not exist, the manager will silently
    fail to use it, so be careful! User-defined modules are not affected
    by this directive. Modules defined in %HTML.CoreModules are not
    affected by this directive.
