+<h4>APS Virtual LINAC Templates</h4>
+
+<p>A new set of templates has been included in R3.14.5 to
+implement a Virtual LINAC in an ioc using databases and
+sequence programs. The Virtual LINAC simulates the generation
+and transmission of an electron beam down a LINAC. Several
+steering coils, BPMs, and other typical accelerator components
+are simulated to provide a realistic interaction between the
+operator and the "LINAC". Since it is an entirely soft application,
+it will work on any platform. An medm display is provided as the
+primary GUI. It can also be used to experiment with other CA
+client tools.</p>
+
+<p>To install the templates, use the following commands:</p>
+ 
+<pre>
+  mkdir <top>
+  cd <top>
+  &lt;base&gt;/bin/&lt;arch&gt;/makeBaseApp.pl -t vlinac vlinac
+  &lt;base&gt;/bin/&lt;arch&gt;/makeBaseApp.pl -i -t vlinac vlinac
+</pre>
