Some points:
+ There are couple of Lintian info/messages you may want to fix.
There is already upstream target in rules file (apt-get orig-source) and I dont think watch file is required explicitly.. If you want I can add it :)
+ Add better extended package description to get more idea for users
about package.
Noted this :) will fix it once I reach home ...
Cheers,
Thanks a lot...
