Converting DOS text files

CR-LF line terminators and final ^Z) for UNIX.

Much to my surprise, he's right that SCO really did make it a program. 
Back in the days of UNIX, we would have used one of the little filter
programs (like tr or sed) that came with the system.  Oh well, "forward
into the past" and "programmer's full employment" and all that.

Why is that a problem?  A filter is just slightly more general: You can
apply a filter to files; a program written to handle only files can't be
used in a pipe sequence.  But let's forge ahead...

A big problem?  Why not (in sh notation):
	for f in *.txt
	do cp $f /tmp/d$$
	   dtox /tmp/d$$ >$f
	done
	rm /tmp/d$$

or go all the way to a UNIX approach and replace the dtox line with
	tr -d '\015\032' </tmp/d$$ >$f
