Well it depends.
I have two options:
- start from scratch
- start with GPL software
In the later case I have to expose...
But I believe that I will publish it even in the first case.
It's not going to be sold, so I don't have to make any garanties.
It's just like burning CDRs - it usually works, but you always know
that it may fail if you are out of luck.
