See `ghcup --help`.
Common use cases are:
```sh
# install the last known "best" GHC version
ghcup install
# install a specific GHC version
ghcup install 8.2.2
# set the currently "active" GHC version
ghcup set 8.4.4
# install cabal-install
ghcup install-cabal
# update cabal-install
cabal new-install cabal-install
```
Generally this is meant to be used with [`cabal-install`](https://hackage.haskell.org/package/cabal-install), which
handles your haskell packages and can demand that [a specific version](https://cabal.readthedocs.io/en/latest/nix-local-build.html#cfg-flag---with-compiler) of `ghc` is available, which `ghcup` can do.
