How to run scheme
-----------------

You have two choices:

* MIT Scheme

  This is the version of scheme used in 6.001.  It sports a powerful
  editor and debugger, but the interface is a bit arcane.  MIT Scheme
  can be downloaded from:
  http://sicp.ai.mit.edu/Fall-2003/SchemeImplementations

  It can also be accessed from a Linux athena machine by typing:
  athena% add 6.001
  athena% 6001-scheme

  Documentation on using it can be found at:
  http://sicp.ai.mit.edu/Fall-2003/manuals/dontpanicnew.html

  The reference manual:

* DrScheme

  This scheme is a more user-friendly editor/evaluator from Rice, but
  learning to use this scheme will not help you in the class.  I
  mention it because you're likely to be able to start working with
  scheme twice as quickly using DrScheme instead of MITScheme.
