-The IO::Like module provides the methods of an IO object based upon on
-a few simple methods provided by the including class: unbuffered_read,
-unbuffered_write, and unbuffered_seek.
+The IO::Like module provides all of the methods of typical IO
+implementations such as File; most importantly the read, write, and
+seek series of methods. A class which includes IO::Like needs to
+provide only a few methods in order to enable the higher level
+methods. Buffering is automatically provided by default for the
+methods which normally provide it in IO.
