Artanis: Modern Web Framework for Scheme

More seriously, Artanis is written using GNU Guile, one of the best implementations of Scheme language.

One day, the folks at GNU were discussing what language they would write the GNU website in - and many chose Python. But I found that strange, because the official extension language of GNU is GNU Guile. And I wondered aloud - why not start a brand new project to provide a web framework written with GNU Guile? To which RMS said, "It's cool, I like this idea."

But at that time, it was just an idea without a plan.

Fortunately, a few months later, the Guile community held a hack-potluck to celebrate Guile2 turning two - which is a contest to write a cool program in a few weeks. And so, Artanis was born.
