Where to put licensing info

[ses5909]

If you create a theme, where do you put the licensing info? In the style.css file? or as a separate text file?

I think either would work, but most seem to be in a separate .txt file.

license.txt file would be where I'd put it (in fact, I will be doing that when I finish working on one of my WordPress theme projects - you and Ben know which one I'm talking about).

I would prefer style.css file because sometimes .txt files have chances of getting deleted. IMO.
