DrRacket Plugins

 (require drscheme/tool-lib)
 (require drscheme/tool)

This manual describes DrRacket’s plugins interface. It assumes familiarity with Racket, as described in the The Racket Guide, and the The Racket Reference, DrRacket, as described in DrRacket: The Racket Programming Environment and the GUI library, as described in The Racket Graphical Interface Toolkit. The Framework, as described in Framework: Racket GUI Application Framework, may also come in handy.

The drscheme/tool-lib and drscheme/tool libraries are for backward compatibility; they export all of the bindings of their drracket counterpart.
