Hi Garima

This serves as a very good introduction. We need however to learn more about 
each of those alternative work before we can make a decision. and not just 
from a code point of view but also in how good a job it does.

Also you seem to have missed that libreoffice 3.5 introduced a new tool based on 
lightproof
http://libreoffice.hu/2011/12/08/grammar-checking-in-libreoffice/

Another avenue worth investigating is an idea i just got. Why not do something 
like bayesian spam filters do. Learn from known goo grammar. And let the user 
allow the filter checker to learn more. With get hot new stuff so you can 
download  other languages as users make them. This would be a totally new way 
of doing it. I'm willing to bet on this. If it doesn't work out well fine, if 
it does then great. Just let us make sure that the teextediting grammarplugin 
is not too tied in to what ever backend we do. Then we can always change our 
mind later.

And doing some frontier work will be really fun.
