Short: Patches dos.library to support ./ and ../

UnixDirs	A program which intercepts calls to dos.library to add the
		UNIX style '.' and '..' syntax for current and parent direct-
		ories, respectively, to file and path names.  I.E., you can
		refer to files in the current directory as './foo' and files
		in the parent directory as '../foo', or any combination of the
		two.  Similar to program on disk 321, but independently devel-
		oped.  Includes source.
