;; Commentary:
;;
;; Standard package installer for vim and neovim plugins.
;; This is implemented as an extension of the `copy-build-system'
;; and takes advantage of vim and neovim's built-in package manager.
;; It extends the installation procedure from the copy-build-system
;; to put files in the correct place and then generates help tags.
;;
;; Code:

(define %vim-build-system-modules
  ;; Build-side modules imported by default.
