+=use-package= is an awesome utility for managing and configuring
+packages in a neatly organized way and without compromising on
+performance. So let's install it using =striaght.el= and have it use
+=straight.el= for installing packages.

+
+#+begin_quote
+Help keeping ~/.emacs.d clean.
+#+end_quote
+
+By default, even for Emacs' built-in packages, the configuration files
+and persistent data are all over the place. Use =no-littering= to help
+contain the mess.

+#+end_src
+
+** Custom file (=custom.el=)
+
+I'm not planning on using the custom file much, but even so, I
+definitely don't want it mixing with =init.el=. So, here, let's give
+it it's own file.

+#+begin_src emacs-lisp

+sensible options. See documentation for the ~make-backup-file~
+variable.
