<p>The console output is color coded - green, amber, magenta for info, warn and crit messages, whereas the log files are just plain text.</p>
<p>There is a maximum of &lt;numberOfLogs&gt; log files with a maximum size of &lt;sizeOfLogs&gt;, at the moment, up to 10 logs of up to 100kB in size are kept, older logs are automatically deleted.</p>
<p>Debug output is not written to the logfile.</p>
<p>In order to start logging, the ALog::init() function has to be called</p>

<p>aMessageHandler Intercepts Messages and prints to console and log file </p>
<p>The message handler is responsible for intercepting the output from qDebug(), qInfo(), qWarning() and qCritical(), formatting them and printing them to the standard console out and to a logfile using QTextStream. Debug messages are not written to the log file. </p>
