+<p>The live-reload module enables Sly programs to react to changes in the
+file system and reload assets automatically, which is useful when
+using external programs such as an image editor or map editor. This
+makes it easy to see the changes made to game assets quickly.

+<dd><p>Return a new procedure that re-applies <code>proc</code> whenever the
+associated file is modified. The new procedure returns a signal
+(see <a href="Signals.html#Signals">Signals</a>) that contains the return value of <code>proc</code>. The
+first argument to <code>proc</code> must be a file name string.
+</p>
+<p>A simple polling method is used to test for updates. Files are polled
+every <code>polling-interval</code> ticks (120 by default).
