Subject Re: reference document which properties are set in which configuration file
Date Sat, 11 Feb 2012 05:08:13 GMT
Harsh, All

This was one of the first questions that  I asked. It is sometimes not clear whether some
parameters are site related  or jab related or whether it belongs to NN, JT , DN or TT.

If I get some time during the weekend , I will try and put this into a document and see if
it helps

Raj
