If a derivation has multiple outputs, `nix-build` will build the default
(first) output. You can also build all outputs:
$ nix-build '<nixpkgs>' -A openssl.all
```console
$ nix-build '<nixpkgs>' -A openssl.all
```
This will create a symlink for each output named `result-outputname`.
The suffix is omitted if the output name is `out`. So if `openssl` has

This will create a symlink `result-man`.
Build a Nix expression given on the command line:
