(description
"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.")
