<p>
    If you've been poking around the various folders in HTML Purifier,
    you may have noticed the <code>maintenance</code> directory.  Almost
    all of these scripts are devoted to flushing out the various caches
    HTML Purifier uses.  Normal users don't have to worry about this:
    regular library usage is transparent.  However, when doing development
    work on HTML Purifier, you may find you have to flush one of the
    caches.
</p>

<p>
    As a general rule of thumb, run <code>flush.php</code> whenever you make
    any <em>major</em> changes, or when tests start mysteriously failing.
    In more detail, run this script if:
</p>

<ul>
    <li>
        You added new source files to HTML Purifier's main library.
        (see <code>generate-includes.php</code>)
    </li>
    <li>
        You modified the configuration schema (see
        <code>generate-schema-cache.php</code>). This usually means
        adding or modifying files in <code>HTMLPurifier/ConfigSchema/schema/</code>,
        although in rare cases modifying <code>HTMLPurifier/ConfigSchema.php</code>
        will also require this.
    </li>
    <li>
        You modified a Definition, or its subsystems. The most usual candidate
        is <code>HTMLPurifier/HTMLDefinition.php</code>, which also encompasses
        the files in <code>HTMLPurifier/HTMLModule/</code> as well as if you've
        <a href="enduser-customize.html">customizing definitions</a> without
        the cache disabled. (see <code>flush-generation-cache.php</code>)
    </li>
    <li>
        You modified source files, and have been using the standalone
        version from the full installation. (see <code>generate-standalone.php</code>)
    </li>
</ul>

<p>
    You can check out the corresponding scripts for more information on what they
    do.
