when I suggested this to my newbie friend, she found the PATH 
problem to be a hassle so I did wrapper scripts.

What we could do though is download it locally then give them a 
"D shell" script to set the PATH up. (Or run it automatically in 
.bashrc or something, but I kinda prefer making it a local script 
they can run without changing any shared files)
