[Ifeffit] artemis split off source

[Paul Fons]

A trivial question perhaps... I understand that the Artemis source is 
being split into a development version and a stable version.  For those 
(like me) who like to live on the bleeding edge, where will the various 
sources reside?  In particular, will the update_horae script upgrade to 
the latest development version (or perhaps there should be a switch for 
using the development version so it can't be executed by accident)?
