<p>excas [options]</p>
<p>This is an example CA server that is sometimes used for testing purposes. An
example server can be created with the makeBaseApp perl script, as descibed in
the application Developer's Guide.</p>

<th>Description</th>

<tr>
<td>-duuuu</td>
<td>set level uuuu for debug messages, where uuuu is an positive integer
number</td>
</tr>
<tr>
<td>-paaaa</td>
<td>prefix all of the PV names below with aaaa changing the name of
"bill" to "xyz:bill"</td>

<td>-s1 is the default it enables periodic scanning of the PV replacing
the PV with its value added with a small random change, -s0 turns off
type of periodic scanning </td>
