+ <p><code>htcacheclean</code> is used to keep the size of
+ <code class="module"><a href="../mod/mod_disk_cache.html">mod_disk_cache</a></code>'s storage within a certain limit. This
+ tool can be either run manually or in daemon mode. When running in
+ daemon mode, it sleeps in the background and checks the cache directories
+ in regular intervals for stuff to be removed. You can stop the daemon
+ cleanly, when sending him a TERM or INT signal.</p>

+ <dd>Daemonize and repeat cache cleaning every <var>interval</var> minutes.
+ This option is mutually exclusive with the <code>-D</code>, <code>-v</code>
+ and <code>-r</code> options. To shutdown the daemon cleanly, just send it
+ a <code>SIGTERM</code> or <code>SIGINT</code>.</dd>
+
+ <dt><code>-D</code></dt>
+ <dd>Do a dry run and don't delete anything. This option is mutually
+ exclusive with the <code>-d</code> option.</dd>
+
+ <dt><code>-v</code></dt>
+ <dd>Be verbose and print statistics. This option is mutually exclusive
+ with the <code>-d</code> option.</dd>
+
+ <dt><code>-r</code></dt>
+ <dd>Clean thoroughly. This assumes that the Apache web server is
+ not running (otherwise you may get garbage in the cache). This option
+ is mutually exclusive with the <code>-d</code> option.</dd>
+
+ <dt><code>-n</code></dt>
+ <dd>Be nice. This causes slower processing in favour of other
+ processes. <code>htcacheclean</code> will sleep from time to time
+ so that (a) the disk IO will be delayed and (b) the kernel can schedule
+ other processes in the meantime.</dd>
+
+ <dt><code>-p<var>path</var></code></dt>
+ <dd>Specify <var>path</var> as the root directory of the disk cache. This
+ should be the same value as specified with the <code class="directive"><a href="../mod/mod_disk_cache.html#cacheroot">CacheRoot</a></code> directive.</dd>
+
+ <dt><code>-l<var>limit</var></code></dt>
+ <dd>Specify <var>limit</var> as the total disk cache size limit. The value
+ is expressed in bytes by default (or attaching <code>B</code> to the
+ number). Attach <code>K</code> for Kbytes or <code>M</code> for
+ MBytes.</dd>
+
+ <dt><code>-i</code></dt>
+ <dd>Be intelligent and run only when there was a modification of the disk
+ cache. This option is only possible together with the <code>-d</code>
+ option.</dd>
