+NPS - Non-Preemtive Thread Scheduling Library
+Copyright (c) 1999 Ralf S. Engelschall.
+
+NPS is a POSIX/ANSI-C based library for Unix platforms which
+provides non-preemtive scheduling for multiple threads of execution
+("multi-threading") inside server applications. All threads run in the
+same address space of the server application, but each thread has it's
+own individual run-time stack and program-counter.
+
+The thread scheduling itself is done in a cooperative way, i.e. the
+threads are managed by a priority- and event-based non-preemtive
+scheduler. The intention is that this way one can achieve better
+portability and run-time performance than with preemtive scheduling.
+The event facility allows threads to wait until various types of events
+occur, including pending I/O on filedescriptors, elapsed timers,
+pending I/O on message ports, thread and process termination, and even
+customized callback functions.
