democratize

Democratize can extract thousands of usage examples (aka "demos") from some
of your favorite Emacs Lisp libraries and, among other things, insert them
into Help (or Helpful) buffers when you look up a function.

These examples come from files that are made available by the very
libraries. Alas, they often end up being overlooked for various reasons.
Overlook them no more: Democratize makes them easily accessible.

For all the details, please do see the README

Open it easily with:
  (find-file-read-only "README.org")   <--- C-x C-e here¹

or from any buffer:
  M-x democratize-see-readme

or read it online:
