unix or mac-style text files?

[Heather Madrone]

I've already encountered a few text file anomalies on OS X. Most GUI applications
seem to default to Mac-style text files (linefeeds only), but shell programs such as
vi do not handle Mac-style text files gracefully.

Is perl on the Mac going to care whether source files are Mac-style or Unix-style?
Is it going to have difficulty reading and operating on either kind of file? What
kind of text files will it write?

Thanks in advance for any illumination.
