Hi,
>What's the format I should use? An email? Comments in the code? A PDF >document? Or? All sorts of comments in the code are always welcome: blurbs at the beginning of each file explaining the main design choices, then smaller comments explaining tricky points, TODO or FIXME when appropriate, etc. But in my previous message I was thinking just short informal emails, to have an idea of the current status, what already works, what doesn't, the major challenges ahead. If you like together with actual patch submissions. Thanks, Paolo
