-** DONE re-work tangling system
-Sometimes when tangling a file (e.g. when extracting elisp from a
-org-mode file) we want to get nearly every source-code block.

-Sometimes we want to only extract those source-code blocks which
-reference a indicate that they should be extracted (e.g. traditional

-I'm not sure how we can devise a single simple tangling system that

-*** new setup
-the =tangle= header argument will default to =no= meaning source-code
-blocks will *not* be exported by default.  In order for a source-code
-block to be tangled it needs to have an output file specified.  This

 by adding a =defadvice= to =org-open-at-point= we can use the common
 =\C-c \C-o= keybinding to open the results of a source-code block.
