It is possible to set up multiple configuration packages. The default configuration package opens the following structures:
You can define other configuration packages by simply making a package that opens module-system and, optionally, built-in- structures, more- structures, or other structures that export structures and interfaces.
For example: =0pt=0pt=0pt =0pt > ,config (define-structure foo (export ) (open module-system built-in-structures more-structures)) > ,in foo foo> (define-structure x (export a b) (open scheme) (files x)) foo>
The ,config-package-is command designates a new configuration package for use by the ,config command and resolution of struct-names for other commands such as ,in and ,open.
