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