NOTE: This version of this package is a work-in-progress, and is not yet intended for use by arbitrary students. The goal of this version is to permit the more adventurous to help test and polish this package, so that in the future it can provide a smooth experience for students. Please direct feedback to Neil Van Dyke <neil AT neilvandyke DOT org>.
This package implements support in PLT Scheme to permit students of Abelson and Sussman’s Structure and Interpretation of Computer Programs (SICP)} textbook to use PLT Scheme tools for the programming assignments. The main reason students may wish to use this package is so that they can use PLT Scheme’s DrScheme programming environment.
Note that this package is not a project of the PLT organization. PLT has a related textbook, How to Design Programs (HtDP), with a different emphasis and a different pedagogic approach. A comparison of the two textbooks is beyond the scope of this document. A 2004 paper by some PLT members, “The Structure and Interpretation of the Computer Science Curriculum” [PDF], provides a PLT perspective on the differences.

Installing this package consists simply of require-ing it from the Internet-based PLaneT software repository, and then restarting DrScheme. The steps in detail for how a beginner may do this through DrScheme are:
1. Make sure that the computer connected to the Internet.
2. Start DrScheme.
3. Change the DrScheme Language to Module. Specifically, select Language|Choose Language... to get the Choose Language dialog, then select Module and click OK.
4. In the top Definitions subwindow, paste the text:
#lang planet neil/sicp "Restart DrScheme now."
5. Click the Run toolbar button.
6. Wait for the "Restart DrScheme now." message to appear in the Interactions subwindow, then quit DrScheme and start it again.
There are two separate ways to specificy use of the SICP Language in DrScheme:
Change the Language to SICP, such as by using Language|Choose Language.... This is the normal way.
When using the Module language, begin the Scheme file with the line:
#lang planet neil/sicp
This package uses the soegaard/sicp PLaneT package by Mike Sperber and Jens Axel Soegaard to implement the SICP Picture Language. Note that you should not use the require form shown in the documentation for that package – this package provides the SICP Picture Language implicitly.
Note that PLaneT package version numbers of neil/sicp are used, rather than maintaning separate version numbers.
