I believe that the first version of cabal-sort is older than this
cabal-install feature. 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. You can
upload packages in topologically sorted order to Hackage, such that
building on Hackage works correctly. Is this also done by cabal-install's
upload command? 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.
