title: installing ifort and icc simultaneously
body: <p>I am trying to install and use both the fortran and c++ compilers from intel on my ubuntu machine.  The problem I am having is that when I update the symbolic links for one I lose the ability to use the other.  The compilevars.sh script add necessary paths for each compiler.</p>
  
  <p>I was thinking I could copy the files for both compilers into a new directory and then update the compilevars.sh to point to the new directories.  Im not sure that this is the best method to do this.  It seems like a common problem, but I can't find anything on google or here that addresses it.</p>
  
  <p>I am using the compilers from this website
