## Usage with the Nextcloud module

The apps will be available in the namespace `nextcloud25Packages.apps`.

The apps will be available in the namespace `nextcloud31Packages.apps` (and for older versions of Nextcloud similarly).

Using it together with the Nextcloud module could look like this:

```nix

```

{

  services.nextcloud = {

    enable = true;

    package = pkgs.nextcloud25;

    package = pkgs.nextcloud31;

    hostName = "localhost";

    config.adminpassFile = "${pkgs.writeText "adminpass" "hunter2"}";

    extraApps = with pkgs.nextcloud25Packages.apps; {

    extraApps = with pkgs.nextcloud31Packages.apps; {

      inherit mail calendar contact;

    };

    extraAppsEnable = true;
