  55 "GNU libsigsegv is a library for handling page faults in user mode. A page
  56 fault occurs when a program tries to access to a region of memory that is
  57 currently not available. Catching and handling a page fault is a useful
  58 technique for implementing pageable virtual memory, memory-mapped access to
  59 persistent databases, generational garbage collectors, stack overflow
  60 handlers, distributed shared memory, and more.")
