| I have always used JP's teeny tiny script he wrote for The Guru 
| magazine 100 years ago.  But, alas it is only for *nix. Here is is.  
| You put it in your path (/usr/local/bin) and call it addcr, then link 
| it to delcr with:
| 
| Ln addcr delcr
| 
| Thatw way it workds in either direction based on the program you call.
| 
| Addcr unixfile windowsfile
| Delcr windwsfile unixfile
| 
| Nifty, compact, protable to any *nix.

| : Carriage-Return converter  - JP. Radley for The Guru
|        # addcr : adds CRs
|        # delcr : removes CRs
|        [ $# -ne 2 ] &&
|        echo Usage: $0 infile outfile && exit
|        case $0 in
|                *addcr) sed s+$+^M+ <$1 >$2;;
|                *delcr) sed s-^M--g <$1 >$2;;
|        esac

Instead of addcr linked to delcr, I now use a script which does either
task.  I call it cr+-.  It could easily be changed to take filename
arguments like addcr|delcr, but as it stands, it's used as a filter.

	#!/bin/sh
	#@(#)cr+-   JPRadley v 1.1
	#@(#)adds CRs if not present, strips them if present
	#@(#)if you just cat this file, you miss its essence, so instead
	#@(#)cat -v this file, so as to see two actual ^M that it
contains
	sed '
	s-^M--g
	t
	s+$+^M+
	t
	'

Like fine wine.....
