I'm working on a scripting language that will handle phrases with the
Braille indicators after the last word. The task right now is to write a
description of the script and then submit it to the list for feedback.
Then it will have to be implemented. Meanwhile, please don't worry about
the dode. Getting the contractions and symbols right can be done without
having the incicators just right.
