Documentation shouldn't use Cabal packages as examples

You shouldn't use Cabal and cabal-install as examples in the cabal documentation. The reader has to mentally quote stuff to understand which level the text is talking about.

Start by locating the Cabal and cabal-install examples throughout the documentation and read the surrounding sections to identify which concepts each example represents. Done means the examples clearly distinguish the relevant levels without requiring readers to mentally quote the names.
