  • Makefile.am, configure.ac, spsize/size.c: Add Simple Priority Scheduler as complement to existing Deterministic Priority Scheduler. This scheduler serves both as an example and as a lighter weight implementation for smaller systems.
  • spsimplesched01/.cvsignore, spsimplesched01/Makefile.am, spsimplesched01/init.c, spsimplesched01/spsimplesched01.doc, spsimplesched01/spsimplesched01.scn, spsimplesched02/.cvsignore, spsimplesched02/Makefile.am, spsimplesched02/init.c, spsimplesched02/spsimplesched02.doc, spsimplesched02/spsimplesched02.scn, spsimplesched03/.cvsignore, spsimplesched03/Makefile.am, spsimplesched03/init.c, spsimplesched03/spsimplesched03.doc, spsimplesched03/spsimplesched03.scn: New files.
