-- Abstract     :
----------------: IO_SUPPORT is a companion package for SYSDEP,
-- a system dependencies package that provides console input and
-- console output without echo on the input and without control
-- character interpretation.  IO_SUPPORT, which employs SYSDEP,
-- provides an input line editor and interfaces to the routines
-- in SYSDEP which provide a greater degree of functionality than
-- SYSDEP itself provides.
--
--      For applications which are embedded and do not require
-- features of TEXT_IO other than simple character or string I/O,
-- IO_SUPPORT with SYSDEP offer an alternative to withing in the
-- entire TEXT_IO package.
--
--      The philosophy behind creating SYSDEP is to provide low-level
-- I/O routines which can be built upon to implement applications which
-- require raw I/O, such as communications servers and character-oriented
-- tools.  IO_SUPPORT goes one step further by providing a set of
-- commonly-used routines around SYSDEP, preventing the need for
-- constantly reinventing the basic wheel.
