Usage: $(basename $0) [options] buildset project [app]
Arguments: buildset     Name of the buildset to create the app for.
           project      Project file to use for the build.

Options: --no-make:     The make phase is skipped.
         --force:       Force full compilation.
         --bloat:       Compile fullfledged BSP.
--> Note: It does not matter where the options are placed: before, in between or after the arguments.
