[wp-hackers] _e(), _() and __()

[Stephen O'Connor]

Okay, just peeked into phpxref... _() does absolutely nothing - it just
returns whatever string it's given. I think I remember something about it
being simply a backwards compatible thing (it's referenced 83 times, all in
either the class-pop3.php or textile1.php. :)

The __() returns a localized or translated string I think. Not exactly sure
how that works. :\ _e() does the exact same thing, only it echo's what it's
given.

Whenever you have a question about functions you should check out the online
version of phpxref. It's been a lifesaver for me.
