 - Add [neo-tree.nvim] as an alternative file-tree plugin. It will be available
   under `vim.filetree.neo-tree`, similar to nvimtree.
+
+- Add `print-nvf-config` & `print-nvf-config-path` helper scripts to Neovim
+  closure. Both of those scripts have been automatically added to your PATH upon
+  using neovimConfig or `programs.nvf.enable`.
+  - `print-nvf-config` will display your `init.lua`, in full.
+  - `print-nvf-config-path` will display the path to _a clone_ of your
+    `init.lua`. This is not the path used by the Neovim wrapper, but an
+    identical clone.
