Re: [ot] extended posix regexp for email address
First off, this is way OT for debian-devel. Pick up a copy of Friedl's
_Mastering Regular Expressions_ to learn more about RE.

And no, it most definetly is not.
Until you've read and understood the monstrosity that is the regexp in
Email::Valid, you should stay well away from writing your own regex to
validating email addresses. Consider using someone else's library to
do the same.

I now know how retro SCOs OSes are. Riotous, riotous stuff. How they
had the ya-yas to declare Linux an infant OS in need of their IP is
beyond me. Upcoming features? PAM. files larger than 2 gigs. NFS over
TCP. The 80's called, they want their features back.
