The old 'disableCheckedExceptions' branch wasn't a particularly nice distribution/storage model of experimental features. For example, it was hopelessly out of date. Redesigned to a separate experimental directory, along with new build scripts, and rewrite it to the new lombok.patcher model.

Unfortunately it doesn't actually work, just yet. Seems to do nothing at all.

+		<h1>Tired of checked exceptions?</h1>
+		<p>
+			This lombok spinoff project consists of a hack that only works in javac - not eclipse or any other IDE.<br />
+			It will completely disable the notion of checked exceptions. You may throw any exception anywhere, and you may
+			also catch any exception anywhere. In standard javac, you may not catch a checked exception that is not declared
+			as thrown by at least 1 statement in your try block, unless it is <code>Exception</code> or <code>Throwable</code>.<br />
+			This restriction is lifted as well.
+		</p>
+		<h3>Usage</h3>
+		<p>
+			Just make sure <code>disableCheckedExceptions-alpha.jar</code> is on the classpath as you compile. For example:<br />
+			<code>javac -cp disableCheckedExceptions-alpha.jar MySource.java</code>
+		</p>
+		<p>
+			Ready to try it out? download it here: <a href="downloads/disableCheckedExceptions-alpha.jar">disableCheckedExceptions-alpha.jar</a>
+		</p>
+		<p>
+			Want to know how its done? Grab the <em>disableCheckedExceptions</em> branch of project lombok. You can browse and download the branch <a href="http://github.com/rzwitserloot/lombok/tree/disableCheckedExceptions">here on github</a>.
