Considering full rewrite
Unipoly's workflow can be improved and users have requested new features, but this codebase is already a few years old and depends on legacy technologies (some librairies cannot be fetched from haskell's repositories anymore!). As discussed with @desroche and some Unipoly member, we might as well rewrite the whole thing.
We will most likely use perl5 with the Dancer web framework, as many applications (including unipoly's member management webapp) already use these technologies.
