+** Snippets
+   YASnippet is the de facto snippet engine. There are two packages
+   for it: one for the engine itself and one with a library of
+   snippets:
+
+   #+begin_src emacs-lisp
+     (use-package yasnippet)
+     (use-package yasnippet-snippets)
+   #+end_src
+
+   I don't want it enabled all the time, only in certain modes. The
+   [[help:yas-minor-mode][yas-minor-mode]] function is provided for this, but it requires that
+   the snippet tables are loaded beforehand, so that has to be done
+   now.

+    There's a lot of boilerplate in C, so I want YASnippet enabled.

 ** C++
    Essentially the same story as for C.
