<div class="textblock"><p>MQTTVersion - display the version and build information strings for a library. </p>
<p>With no arguments, we try to load and call the version string for the libraries we know about: mqttv3c, mqttv3cs, mqttv3a, mqttv3as. With an argument: 1) we try to load the named library, call getVersionInfo and display those values. 2) If that doesn't work, we look through the binary for eyecatchers, and display those. <br  />
 This will work if the library is not executable in the current environment. </p>
