Hi, I'm looking for reference about run rule and the only thing I can find is this short reference: http://www.boost.org/doc/tools/build/doc/html/bbv2/reference/rules.html pointing to the Testing section which is currently blank: http://www.boost.org/doc/tools/build/doc/html/bbv2/tutorial/testing.html Would there be any chance to get this part updated? I'm looking for details about the run rule arguments: rule run ( sources + : args * : input-files * : requirements * : target-name ? : default-build * ) I'd appreciate if someone could explain what is the differences: sources vs input-files or args vs input-files.
