 - Document new ConfigSchema setup and format; dev-includes.txt is a base

 IMPORTANT FEATURES
 - Get everything into configuration objects (filters, I'm looking at you)

+
+<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.
