Heading "Usage" towards the end. I quote the relevant passage: - To run your program from within Eclipse, create a *Run Configuration* of type *Java Application*. The name of the main class is the module name you used in the Frege file where the main function you want to run is located. (For some mysterious reason, Eclipse cannot find this name, so you have to type it.) You may also need to give appropriate values for -Xmx and -Xss as *VM arguments* under the *Arguments* tab. Give the *Run Configuration* a meaningful name and run it from the Eclipse *Run* menu. Standard input and output will be done through the console view. -- You received this message because you are subscribed to the Google Groups "Frege Programming Language" group.
