Another important consideration in team software development is the ability to group classes, applications, and prerequisites into multiple configurations. Because of this ability to combine units of software in multiple ways, a team can reuse software for multiplatform applications and customize software for similar purposes.

Specifying platform-specific configurations is done in the Application Editions browser, which you access by selecting Application Editions from the full Tools menu. The Smalltalk User Guide describes in detail how to group classes and applications into platform-specific configurations.
