[plt-scheme] instructions for installing plt language from planet

I have a PLT Language that I'd like to have installed from a PLaneT 
package.  What are some simple instructions that I can give a new 
student for how to install this PLaneT package?

Installation is a one-liner if I have the user go to a command prompt, 
but that might be intimidating, so I was thinking of having them do it 
through DrScheme.

With DrScheme, the steps I can think of to get them to reliably execute 
a "require" form in a Language that supports it seem convoluted.  (Start 
DrScheme, make sure you a new window with no file in it, change language 
to Module using such-and-such series of steps, enter "(require (planet 
foo/bar))" in the interactions subwindow, wait for the "PLaneT: Finished 
with foo/bar." message, quit DrScheme and start it up again.)
