  40    (description
  41 "GNU libsigsegv is a library for handling page faults in user mode. A page
  42 fault occurs when a program tries to access to a region of memory that is
  43 currently not available. Catching and handling a page fault is a useful
  44 technique for implementing pageable virtual memory, memory-mapped access to
  45 persistent databases, generational garbage collectors, stack overflow
  46 handlers, distributed shared memory, and more.")
