Cou someone help me a little bit with git?  I don't know how to
access a remove branch. I tried

Neither

   git clone --reference /usr/src/linux-git  git://git.infradead.org/libertas-2.6

and

   git clone --reference /usr/src/linux-git -o libertas git://git.infradead.org/libertas-2.6

But neither would give me anything than a branch "master".
