Releasing blib.py?

I used blib.py in the bot I created (User:WingerBot), with a few changes (mainly, I extracted calls to pywikibot.output() to a function and changed it to directly output UTF-8 encoded text to stdout/stderr, because pywikibot.output() behaves strangely when stdout is redirected to a file, automatically transliterating Arabic text). I would like to make the source code for the bot available. Are you willing to allow blib.py to be released? If so, what license do you want on it (e.g. GPL or MIT)?

GPL is ok.

Thanks. Code is now on github, at [1].
