To create a “blank” MarSystem to begin programming, use
path/to/marsyas/scripts/createMarSystem.py MyMar
where MyMar is the name of your new MarSystem. This script will
create MyMar.h and foo.cpp in your current
directory.
If you want to create these new MarSystems in the src/marsyas/
directory, go to that directory and call the script. Relative paths are
fine, for example ../../scripts/createMarSystem.py MyMar
(on *nix).
