Mkovmake is an optimizing overlay makefile generator-- in other words, you use it in the Makefile of a large program that you are trying to make, and it generates base and overlay definitions and an ld command that would correctly load the object modules. This avoids incessant calculations of module sizes each time sources are changed, and allows large programs to be easily put together on a PDP-11. It is designed to allow varying levels of user participation in case the user can optimize better than mkovmake's static algorithm. Try it out; the man page even has examples. -- Dennis Flaherty dennisf@ndcvx.cc.nd.edu U of Notre Dame Dept. of Electrical Engineering Notre Dame *tells* me what opinions to have.
