Forum OpenACS Q&A: Response to OpenACS 4 on Mac OS X (and Darwin) HOWTO now available
^M's. Strangely, it seems that emacs is smart enough that it
recognizes that this is a Mac file, and it keeps everything in "Mac

edit out the ^M characters. I guess it probably has some facility
for translating back and forth, but I couldn't figure it out, so pico
fixed the problem for now.
