Thank you!
I wanted to get some early indications instead of spending months in my ivory tower
thinking about how to unleash greatness on the surface of the earth.

Iterative releasing has a greater chance of going somewhere... at least I hope so.

Not yet.

Right now it is too much in a flux to write up a grammar for the textual
I feel that it is most important to get the visuals down with a rough draft of what
the textual counter part should be and then we can move on to a more rigorous
specification of the textual format.

But I would be interested to hear what would be a good format for the grammar.
Should it be an antrl grammar? Or a PEG for Neotoma? Or???
