/****************************************************************************
Unit Bufio; Interface
*****************************************************************************
Bufio implements the structured reading of the imput stream. As such, it
will handle the necessary byte-swapping that must occur when reading a
native Macintosh file.
This interface will also shield the calling application from knowledge of
the source format (file vs. memory).
Module Prefix: IO
