Note that 'cabal upgrade' upgrades everything you've currently got
installed (which in general is not necessarily possible).

The standard workflow is just:

cabal update            #download list of new packages
cabal install yi        #install latest version of yi

The difference between
$ cabal install yi
and
$ cabal upgrade yi
is whether we try to upgrade the dependencies of yi as well or just try
to use any currently installed versions of yi's dependencies.

If anyone has some good ideas on how we can make the first step more
automatic then see ticket #359
