-- SYNOPSIS -- Routines to change unix file names to mac file names
--
-- DESCRIPTION
-- Dmake sometimes assumes that files have '/' as a directory parameter in some makefiles.
-- This works, even on DOS, but not on the Mac. In fact, on the Mac, you can't even do a
-- a simple switch of ':' for '/' because all other the Mac has decided to reverse the use
-- of a first-character directory delimiter to mean a relative path rather than absolute path.
-- (i.e., ':test:b' means directory test is relative to the current directory, rather than
-- a top-level directory. Thus, this file attempts to do the directory conversion behind
-- the back of the rest of the program.
