Markdown licensing

[John Gruber]

I'm leaning towards releasing Markdown 1.0.1 under a BSD-style
license instead of the current GPL. If you're not a license nerd,
feel free not to care. The gist of it is that the BSD is
significantly more liberal than the GPL, and would pretty much free
everyone to go ahead and include Markdown in their own projects,
regardless how their own projects are licensed.

If anyone has any thoughts on this, now would be the time to speak
up.
