Ah yes, looks like we developed it concurrently. cabal-install 0.10.2 came out in March 2011 and cabal-sort 0.0.1 in May. > Nonetheless, cabal-sort can be used for other > purposes, too. E.g. you can use plain Cabal installation, when 'cabal > install' does not work due to problems in constraint solving.

No it's not, it's an interesting point. In practice with the current builder you'd be very unlucky to hit the exact time when it kicks off builds (only a few times a day). With the new server it's likely to be more of an issue since that will allow lots of builder clients. > You can also use cabal-sort for stepping into package directories > and do some manual updates before installing. > > However, I will add references to the new cabal-install features in the > documentation of cabal-sort. Cheers. I wonder if you have any suggestions for UI changes/improvements for cabal-install for working with related sets of local packages (something it's fairly weak on at the moment). Are there things in cabal-sort you think we should just lift directly into cabal-install or variations etc?
