+ (description
+ "Pth is a very portable POSIX/ANSI-C based library for Unix
+platforms which provides non-preemptive priority-based scheduling for
+multiple threads of execution (aka ``multithreading'') inside
+event-driven applications. All threads run in the same address space of
+the server application, but each thread has it's own individual
+program-counter, run-time stack, signal mask and errno variable.
+
+The thread scheduling itself is done in a cooperative way, i.e., the
+threads are managed by a priority- and event-based non-preemptive
+scheduler. The intention is that this way one can achieve better
+portability and run-time performance than with preemptive
+scheduling. The event facility allows threads to wait until various
+types of events occur, including pending I/O on file descriptors,
+asynchronous signals, elapsed timers, pending I/O on message ports,
+thread and process termination, and even customized callback functions.
+
+Additionally Pth provides an optional emulation API for POSIX.1c
+threads (\"Pthreads\") which can be used for backward compatibility to
+existing multithreaded applications.")
