    longDescription = ''

      Elpaca is an elisp package manager. It allows users to find,

      install, update, and remove third-party packages for Emacs. It

      is a replacement for the built-in Emacs package manager,

      package.el.

      Elpaca:

       - Installs packages asynchronously, in parallel for fast, non-blocking installations.

       - Includes a flexible UI for finding and operating on packages.

       - Downloads packages from their sources for convenient elisp development.

       - Supports thousands of elisp packages out of the box (MELPA, NonGNU/GNU ELPA, Org/org-contrib).

       - Makes it easy for users to create their own ELPAs.

      Elpaca has been adapted for Emacs managed via Nix. To activate

      Elpaca, this snippet can be used within your init.el:

      ```elisp

      (add-hook 'after-init-hook #'elpaca-process-queues)

      (elpaca-use-package-mode) ;; Optional, for use-package support

      ```
