[Comm-en] Sisyphus.....Alt.....few questions

[Chad]

I would like to try some of the Sisyphus packages. I do NOT want to mess 
up my current install of AltJr2.2. Is it best to do a second intall of 
AltJr2.2 do all the updates and they go to the repositories and select 
the sisyphus repositories? Then update everything sisyphus or can I just 
  do certain progams?
