Sorry for being ambiguous. I didn't have scripts in mind. Converting them
is no big deal. I thought of files read in by scripts. Some time ago I
wrote a script that converts flat javadoc generated HTML files into a
folder hierarchy and wondered why MacPerl choked on the larger files --
well, of course they use linefeeds at least the ones that I've seen so far.

Similar problems occur in lots of other cases where files from different
platforms are involved, especially when they're acquired in archives and no
implicit conversion is done.

I'd like best if MacPerl had an option to treat \015, \012 and \015\012 as
line endings. Thinking of it this might be very useful when Rhapsody
arrives as we probably have to get used to different line-endings in files
created on the same machine.
