multi-lingual ikiwiki

I know I haven’t started writing yet, I’m already worried about technical issues. How can I handle writing in different languages here? I’ve seen the po plugin but it requires me to set a “Master language” for the whole system. Rather, I want to be able to set different master languages for each post.[^1] Because sometimes I start writing in French, some other times I start writing in English. Most of the time I don’t translate myselft. So translation isn’t really what I’m looking for.

If you’ve got any suggestion on how to solve this, you’re very welcome. Until then, I’ll just stick to tagging.

[^1]: You might wonder: what for? I’d like to add a lang="en|fr" attribute for each post, that would allow me for instance to enable hyphenation at line-breaks.
