Exactly.  To my mind, the biggest problem is that it is difficult,
time consuming, and error prone to encode a complex fitting model
using Artemis' GUI.  I forsee that one of my common uses of Demeter
will be to encode a complex fitting model in a one-off script and have
that script write out an Artemis project file.  Then I'll get the good
parts of the GUI while using something automated to deal with the
tedious parts.

In fairness, Ifeffit is great at doing its low-level thing.  It's just
that low-level tools tend not to scale up gracefully.

Thanks for all the kind words, Mauro.  I am excited that you get the
point of middleware and that you get the point of using Subversion.
Even if you use and don't contribute, Subversion lets you always use
up-to-the-minute code.
