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