Or it's a problem with pre-OS X Mac line endings. If so, you could
modify the above perl script, but I'd suggest an easier way:
Use the UNIX command "tr" to replace the special character ^M (or
015) by UNIX line endings (012). The command for that would simply be
tr "\015" "\012" < INTEXTFILE > OUTTEXTFILE
where INTEXTFILE is the bad file and OUTTEXTFILE is the resulting
fixed version.
I actually have this as a script called mac2unix, created analogously
to what David described. Its content is a bit shorter -
#!/bin/csh
tr "\015" "\012" < $1 > $2
That's all - you'd invoke this with "mac2unix INTEXTFILE
OUTTEXTFILE" from the Terminal command line. I remember using this a
long time ago because TeX files from the old Mac OS were being
typeset under OS X as if each line were a separate paragraph... (or
something like that)... hope this helps with the verbatim problem, too.
OK - before sending this off I just checked if there's an _even_ more
"user-friendly" solution because I recall that some people seem to
dislike the command line... And indeed, there is a bona fide
application that does this:

Have fun,
