title: Use of JCLLIB and DOCLIB in ESP scheduler application is not clear
body: <p>I can see in some applications, JCLLIB and DOCLIB both are present and in some applications both are not mentioned. So in such a case, where both are not mentioned, is there any default library which ESP searches? I mean what will happen in this case? Being quite naïve in this, I am not able to understand. Please share your knowledge.</p>
