title: How to set PVM's environment?
body: <p>i'm using Ubuntu v11.04. How to set PVM's environment variable ?</p>
  
  <p>in the handbook, it writes, "the easiest method is to set these variables in your .cshrc file", but i can't find any .cshrc file. i find cshrc.stub.</p>
  
  <p>if anyone has ever used PVM?</p>
