This toolkit primarily provides modules for performing both traditional and
object-oriented i/o) on things other than normal filehandles; in particular,
IO::Scalar, IO::ScalarArray, and IO::Lines.

In the more-traditional IO::Handle front, we have IO::AtomicFile which may be
used to painlessly create files which are updated atomically.

And in the "this-may-prove-useful" corner, we have IO::Wrap, whose exported
wraphandle() function will clothe anything that's not a blessed object in an
IO::Handle-like wrapper... so you can just use OO syntax and stop worrying about
whether your function's caller handed you a string, a globref, or a FileHandle.
