body: <p>How can we read a config file stored at a location relative to the Mirth Connect Installation directory?</p>
  
  <p>For example if Mirth is installed in /opt/Mirth-Connect directory and I want to read a file from /opt/Mirth-Connect/conf directory without specifying the fully qualified path name.</p>
  
  <p>We are using multiple instances of Mirth for different environments which are installed on the same machine, So I can't hard code full path in channel configurations.</p>
