Note: The Modules system defined on this page (and incorporated in 3.3alpha) is no longer part of the mainline Squeak release. See Modules Discussion at OOPSLA 2002 and Squeak Central for more details.

This is the place for growing documentation and everything else related to the Modules/Repositories/Packages system being added to Squeak 3.3alpha. (Modules 2001-09-26) Like everything else, if you miss something here then create it!

Experimental code for Modules
(Squeak 3.3alpha can be downloaded from the 3.3alpha directory of any of the Squeak FTP Mirrors.)

Mailing list

There is a group of Squeakers actively working on the modules code and using a separate, temporary mailing list for these discussions. Visit http://lists.advantive.com/listinfo/sqmodules to view the list archives or join the list.
