In Section 2.3, "Basic use of the MLWorks project system" we saw how to use the project workspace to set up a project file for compiling a set of dependent source files into object files, and how to load those files into the interactive environment. In this sections we examine some further uses of the project system, namely how to display source dependencies, how to specify libraries and subprojects for a project, and how to set compilation for different configurations of, for example, the application platform.
