+* Setting up =load-path=
+
+  First, to help, I create a function that takes a path, adds it to
+  =load-path= and then checks to see if there is a file named
+  ~loaddefs.el~ in the given path. If there is, it loads it. This
+  ~loaddefs.el~ file is something that is created from autoload cookies
+  in the files in some of these paths.
+
+  Since the =load-path= is also important during byte-compilation, this
+  function should be defined both at run-time and compile-time.
+
+  #+BEGIN_SRC emacs-lisp
+    (eval-and-compile
+      (defun oni:loadpath-add-and-autoload (path)
+        "Add PATH to `load-path' and load a `loaddefs.el' if it exists."
+        (add-to-list 'load-path path)
+        (let ((loaddefs (concat path "/loaddefs.el")))
+          (when (file-exists-p loaddefs)
+            (load loaddefs)))))
+  #+END_SRC
+
+  After that I add some directories to my =load-path= so I can use these
+  libraries when wanted. One of these is the ~site-lisp~ directory in my
+  ~.emacs.d~ directory, which is where I keep most of my personal
+  non-ELPA modules (like module-specific initialization files). There
+  are also some directories I include in ~vendor-lisp~, which is where I
+  keep modules that I didn't write myself and, for some reason, can't
+  or don't want to use ELPA for. Again it is important to realize that
+  this information is relevant both at run-time and compile-time, so
+  we wrap it with an =eval-and-compile=.
