No, you can also

$ ./runghc ./Setup.[l]hs configure --enable-library-profiling --user --
prefix=$HOME/.cabal
$ ./runghc ./Setup.[l]hs build
$ ./runghc ./Setup.[l]hs haddock --hyperlink-source
$ ./runghc ./Setup.[l]hs install

It's just more typing [protip: create a batch file (that is the Windows 
analogue of a shell-script, isn't it?)].
