+<p>Sometimes it is useful to run <span class='object_link'><a href="Rubu.html" title="Rubu (class)">Rubu</a></span> automatically whenever a file changes.
+Linux provides a facility called <strong>inotify</strong>, which can be
+used in Ruby through “rb-inotify” gem. Automatic update example program is
+in:</p>
+
+<pre class="code ruby"><code class="ruby"><span class='id identifier rubyid_example'>example</span><span class='op'>/</span><span class='id identifier rubyid_up'>up</span><span class='op'>-</span><span class='id identifier rubyid_to'>to</span><span class='op'>-</span><span class='id identifier rubyid_date'>date</span>
+</code></pre>
+
+<p>This program runs <span class='object_link'><a href="Rubu.html" title="Rubu (class)">Rubu</a></span> each time there is a change in “src” or in “bin”
+directory. It compiles and generates C files if necessary. If there are new
+compilation requirements coming, before all previous have been completed,
+it will continue compilation. When all compilations are done (i.e. none
+pending), it will call <span class='object_link'><a href="Rubu.html" title="Rubu (class)">Rubu</a></span> to perform linking. “up-to-date” displays
+status messages in red and green on the screen. If it is started with “-v”
+option the compile commands are visible, and if it is started with “-d”
+option, there is extra delay in compilation command.</p>
+
+<pre class="code ruby"><code class="ruby">cd example
+up-to-date -v -d</code></pre>
+
+<p>This is useful if you want to play around with the pending compilation
+processes when new changes are coming in. You can make (dummy) changes to
+“hello_world.c” (for example), and follow the updates in the terminal where
+you started “up-to-date”.</p>
