-----------
A gettext compatible i18n library for modern JavaScript Applications

by Alex Sexton - AlexSexton [at] gmail - @SlexAxton
WTFPL license for use
Dojo CLA for contributions

Jed offers the entire applicable GNU gettext spec'd set of
functions, but also offers some nicer wrappers around them.
The api for gettext was written for a language with no function
overloading, so Jed allows a little more of that.

Many thanks to Joshua I. Miller - unrtst@cpan.org - who wrote
gettext.js back in 2008. I was able to vet a lot of my ideas
against his. I also made sure Jed passed against his tests
in order to offer easy upgrades -- jsgettext.berlios.de
