When debugging issues on embedded systems, it is often helpful to insert textual printouts at various locations in the running program in order to attempt to isolate the moment at which issues occur. The following simple component allows inserting such printouts in the runtime without having to modify other components. It's subroutines simply print a message customized by a template parameter.
