FWIW, I've made good progress in getting the necessary functionality into the ManifoldCF scripting language, but I'm still missing a number of key features. When these are ironed out I will be putting together a site page on the script and on how to use it, with some examples. Based on the speed of progress so far, I'd guess that all of this will probably not be complete until after Labor Day. I hope to cut the first RC for the 0.3-incubating release then, if everyone else is ready.
Thanks, Karl
