Subject Re: Whirr installation issue
Date Wed, 18 Apr 2012 22:15:34 GMT
Hi Ashish,

Just wanted to clear a little more on this ..

So on my local ubuntu machine I will install whirr 0.7.1 . In that case
from which site I should download this for ubuntu 11.10.
Any clue is appreciated.

Thanks in advance
Debashis
