how do i generate the wiki to try it out locally?

[llogiq]

python util/update_wiki.py

[oli-obk]

now it works (no more trailing whitespace, + the fix actually fixes something)

[mcarton]

Thanks, I had not idea python's regex supported something like that.

[oli-obk]

neither did I... I don't know any python to begin with ^^
