  43     (description
  44      "GNU Pth is a portable library providing non-preemptive, priority-based
  45 scheduling for multiple execution threads.  Each thread has its own
  46 program-counter, run-time stack, signal mask and errno variable.  Threads are
  47 scheduled in a cooperative way, rather than in the standard preemptive way,
  48 such that they are managed according to priority and events.  However, Pth
  49 also features emulation of POSIX.1c threads (\"pthreads\") for backwards
  50 compatibility.")
