+But wait, what if you want to export things for an os you're not using?
+
+Easy, just create a couple options files like so:
+
+#+BEGIN_SRC sh :tangle no
+name=option
+echo "(setq ${name}-p t)" > options/${name}.el
+echo "(setq ${name}-p nil)" > options/no-${name}.el

+
+#+BEGIN_SRC sh :tangle no

+#+END_SRC
+
+Etc...
+
+I wouldn't do this exactly, while you could, thats just too much to need to
+remember to type. The simplest way to do things is to just create an
+*options/$(uname -n).el* file with all the options you need defined. Note that
+in the or *BEGIN_SRC* lines you can use elisp to control when/how something should or
+should not get tangled.
+
+Example use of tangle/file, note the final option is just elisp and we just
+use *bound-and-true-p* to detect if we have a predicate or not.

+#+BEGIN_SRC emacs-lisp :tangle no
