title: git + assembla + multiple ssh keys/multiple computers
body: <p>I have multiple computers working on the same project, and I'm using a free assembla git repo account to manage all this. </p>
  
  <p>In order to access the git repo, I need to generate unique SSH keys on each computer.
  However, a computer might be working on other assembla projects as well, so there seems to be a conflict whenever I generate a new ssh key (like I have to keep replacing the id_rsa files).
  Once I recreate the id_rsa files (and replace them) on a local machine, it loses access to the previous assembla git projects using the previously-generated ssh key.</p>
  
  <p>I'm fairly new to the whole git business, and trying to learn as I go.</p>
  
  <p>I found something that sounded like a solution to my problem:
  "Different SSH keys for different projects"

  <p>However, I don't understand how to do #1?  It says to "place somewhere in $PATH this script (let its name will be gitssh)", but I don't know what/where "$PATH" is?</p>
  
  <p>Any help would be greatly appreciated.
  Thanks!!</p>
