            - Path of the binary to use. This can either be C(pacman) or a pacman compatible AUR helper.
            - Pacman compatibility is unfortunately ill defined, in particular, this modules makes

              some AUR helpers (notably, C(yay)).

              if I(name) and I(upgrade) are not specified. This will change in community.general 5.0.0.
              See the examples for how to make the module behave as it will in 5.0.0 right now, or how
              to keep the current behavior with 5.0.0 and later.

        description:
            - Whether or not to upgrade the whole system.
              Can't be used in combination with C(name).

        default:
        type: str

notes:
  - When used with a C(loop:) each package will be processed individually,
    it is much more efficient to pass the list directly to the I(name) option.
  - To use an AUR helper (I(executable) option), a few extra setup steps might be required beforehand.
    For example, a dedicated build user with permissions to install packages could be necessary.
