     - This module works on Debian and Ubuntu and requires only C(python-apt) package.
     - This module supports Debian Squeeze (version 6) as well as its successors.
     - This module treats Debian and Ubuntu distributions separately. So PPA could be installed only on Ubuntu machines.
-    - For PPA support you either need python-pycurl or wget on the client.
