Agreed.  And it doesn't convert CRLF to LF, it simply kills any CR.

dos2unix from sysutils.  (No Mac conversion, however... but then
again, most people need to convert MS-DOS files anyway).

Never used anything else, and certainly wouldn't use tr for this.
dos2unix is a lot simpler than this tr solution... "dos2unix
dos.file", done.  (Of course you might have this in your list
already...)

Alternatively, mention recode.  But... that's lots more powerful, and
thus a lot more complicated.  (You *could* mention recode in a short
sentence "For universal recoding problems, there's recode" or
s.th. like that.  *Pointers* to advanced tools/topics are a good
thing, IMHO... always give people the option to learn.  It's not our
fault if people don't learn... but it is our fault if we don't show
them where they can).
