This is somehow suggested in "Libraries of Lisp Code for Emacs" which I = intend to refer to so I'm not sure there is a need to put too much = emphasis here. > If the file is needed simply because the user decided to split their > `.emacs` file into several separate files, then `load` (or `require`) = is > probably fine.

Well, actually all this started because I wanted to install Drew's = help-fns+.el and it happens that Drew uses "require". So, in case I want to add a similar feature set, would 'require be too = much ? Would (autoload 'help-fns+) be sufficient ? When I have the information about this, I think I can make a = satisfactory patch to the manual :) Keep in mind that this addition is for users who know a minimal subset = of emacs lisp (enough to play with their init file), not for authors.
