1. I've downloaded you source code microwin-frye-nanosteve.1.tar.bz2,
and readed it, I found you make a lot of change from v0.89.
Can you describle the concept of your work simply? So I can
understand your code easily. Where should I start it?
2. You said "except stipples and dashlists are still broken",
I want to know do you still working on it? And do you have a
schedule to release it? Is the following address still available
in the future?
