-    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
-      ```
