libfile-map-perl - 0.67-2 main

File::Map maps files or anonymous memory into perl variables that can be read
just like any other variable. Files are unmapped when the scalar variable is
destroyed, even in multithreaded programs.
.
Mapped memory is shared between threads and forked processes, and can be
returned to the system when no longer needed. File::Map has built-in support
for thread synchronisation, and is safe yet fast.
