Yes. But bible would be plain text files.. Properties would be used for 
index only...

I didn't plan to do xml parser. I was looking for sollution similar to 
Spehen's, but plain text, no decoding of bible or anything. Stephen 
implemented some coding style which uses less data, I was working toward 
normal text format bible, that is in jar (so it's compressed to 1.5 Mb), 
and is much easer to access...

Take care,
Andy
