description         GNU Portable Threads
long_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 ("multithreading") inside server applications. All \
                    threads run in the same address space of the server application, but \
                    each thread has its own individual program-counter, run-time stack, \
                    signal mask and errno variable.
