+
+HtmlTidy is a plugin for the popular cross-browser TTY WYSIWYG editor,
+htmlArea (http://www.interactivetools.com/products/htmlarea/). HtmlTidy
+basically queries HTML Tidy (http://tidy.sourceforge.net/) on the
+server side, getting it to make-html-nice, instead of relying on masses
+of javascript, which the client would have to download.
+
+Hi, this is a quick explanation of how to install HtmlTidy. Much better
+documentation is probably required, and you're welcome to write it :)
+
+
+* The HtmlTidy directory you should have found this file in should
+  include the following:
+
+  - README
+        This file, providing help installing the plugin.
+
+  - html-tidy-config.cfg
+        This file contains the configuration options HTML Tidy uses to
+        clean html, and can be modified to suit your organizations
+        requirements.
+
+  - html-tidy-logic.php
+        This is the php script, which is queried with dirty html and is
+        responsible for invoking HTML Tidy, getting nice new html and
+        returning it to the client.
+
+  - html-tidy.js
+        The main htmlArea plugin, providing functionality to tidy html
+        through the htmlArea interface.
+
+  - htmlarea.js.onmode_event.diff
+        At the time of publishing, an extra event handler was required
+        inside the main htmlarea.js file. htmlarea.js may be patched
+        against this file to make the changes reuquired, but be aware
+        that the event handler may either now be in the core or
+        htmlarea.js may have changed enough to invalidate the patch.
+	
+	UPDATE: now it exists in the official htmlarea.js; applying
+	this patch is thus no longer necessary.
+
+  - img/html-tidy.gif
+        The HtmlTidy icon, for the htmlArea toolbar. Created by Dan
+        Petty for The University of Western Australia.
+
+  - lang/en.js
+        English language file. Add your own language files here and
+        please contribute back into the htmlArea community!
+
+  The HtmlArea directory should be extracted to your htmlarea/plugins/
+  directory.
+
+
+* Make sure the onMode event handler mentioned above, regarding
+  htmlarea.js.onmode_event.diff, exists in your htmlarea.js
+
+
+* html-tidy-logic.php should be executable, and your web server should
+  be configured to execute php scripts in the directory
+  html-tidy-logic.php exists in.
+
+
+* HTML Tidy needs to be installed on your server, and 'tidy' should be
+  an alias to it, lying in the PATH known to the user executing such
+  web scripts.
+
+
+* In your htmlArea configuration, do something like this:
+
+    HTMLArea.loadPlugin("HtmlTidy");
+
+    editor = new HTMLArea("doc");
+    editor.registerPlugin("HtmlTidy");
+
+
+* Then, in your htmlArea toolbar configuration, use:
+
+    - "HT-html-tidy"
+        This will create the 'tidy broom' icon on the toolbar, which
+        will attempt to tidy html source when clicked, and;
+
+    - "HT-auto-tidy"
+        This will create an "Auto Tidy" / "Don't Tidy" dropdown, to
+        select whether the source should be tidied automatically when
+        entering source view. On by default, if you'd like it otherwise
+        you can do so programatically after generating the toolbar :)
+        (Or just hack it to be otherwise...)
+    
+
+Thank you.
+
+Any bugs you find can be emailed to zeno@ucc.gu.uwa.edu.au
