Interestingly enough, I stumbled upon mgwiki there, and it looks like something to look into later on. But I digress.
Plus I have to set up things such that it is relatively easy to propagate fixes either way across ‘bare’ Yaki and the production site (and Subversion branching is not something I want to have to fiddle with).
Still, it’s a step. More to come in the next few days.
