+The autocommand must be defined before the colorscheme is set. To overwrite
+any highlight link that is already established in `colors/dracula.vim`, you
+will need to use the bang (!) modifier on the |hi-link| command.
+
+For more than one customization, it will be easier to define a function that
+can be called from the autocommand: >
+
+    function! s:customize_dracula() abort
+      " Link a highlight group to a predefined highlight group.
