This module provides subs that allow you to read or write entire files
with one simple call. They are designed to be simple to use, have
flexible ways to pass in or get the file contents and to be very
efficient. There is also a sub to read in all the files in a
directory other than C<.> and C<..>

These slurp/spew subs work for files, pipes and
sockets, and stdio, pseudo-files, and DATA.
