Hello! I've been interested in hacking language-c library a bit for my needs. (If it turns out useful and successful, I'll tell about it.) And I've cloned the repo listed at https://hackage.haskell.org/package/language-c-0.4.7 , namely: http://code.haskell.org/language-c Apart from my special hacks, I've also fixed some typos and so on. But then I discovered that if I want to publish them on hub.darcs.net , I need a darcs-2 repo, and the initial one which I used for cloning is a darcs-1 repo. I could do the conversion to darcs-2, but I read that it is not reproducible: run several times on the same set of patches it will give different results. As I've discovered also a language-c repo at hub.darcs.net which looks like an upstream repo: http://hub.darcs.net/visq/language-c , I'm in doubt whether I should continue making my patches against the darcs-1 repo which is said to be upstream at hackage or against http://hub.darcs.net/visq/language-c whichis not officially declared as the upstream but looks more fresh. ..if I want to be able to send some of my patches upstream. Best regards, Ivan
