How to use Itranslator? -

I found at
http://www.omkarananda-ashram.org/Sanskrit...nslator2003.htm
a free translator which converts ITRANS 5.30 encoded text or text files into Devanagari or Transliteration (True Type), which can be saved in Rich Text Format. Somehow I cant figure out how to use it properly? Anybody ever worked with it? Thanks.

I believe there's a rather clear manual that comes along with it, right under the download links. Try that for starters.
