<para>
This clears the cache for a specific template. If you have
multiple caches for this template, you can clear a specific
cache by supplying the cache id as the second parameter. You
can also pass a compile id as a third parameter. You can "group"
templates together so they can be removed as a group. See the
<link linkend="caching">caching section</link> for more
information. As an optional fourth parameter, you can supply a
minimum age in seconds the cache file must be before it will
get cleared.
