  + h So, without further ado, let\'s build our package:

  + x nix build "$(dirname "${BASH_SOURCE[0]}")" -L

  +

  + h Maybe there was no output\; this means that package was already built and put into the Nix store

  + x nix build "$(dirname "${BASH_SOURCE[0]}")" -L --rebuild

  +

  + h By default, we get a ./result symlink

  + x find -L ./result

  +

  + h And we can run our executable

  + x ./result/bin/wttr-delft
