%description
This 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

The library is available as 32-bit and 64-bit.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc -q64" or "gcc -maix64".
