Hello,

I'm finding that I frequently work with Org-mode files that need

different configurations. I typically have a #+begin_src emacs-lisp

block in these files that I can execute with C-c C-c, so that emacs

behaves the way the file requires for the task at hand. When I'm

done, though, and jump onto the next task, which might depend on my

standard configuration to work correctly, I sometimes find that the

changes I've made break things. At this point, I typically save,

quit emacs and start over.

What I'd like to do is be able to have, in each file that contains

an emacs-lisp source block that changes the configuration, a

corresponding source code block that puts things back the way they

were before the block was executed.

Perhaps there is an easy way to do this?

What about making configuration variables buffer-local in the block
you execute? Once the buffer is killed, you should be back to your
previous configuration.

For example:

 #+BEGIN_SRC emacs-lisp
 (make-local-variable 'sentence-end-double-space)
 (setq sentence-end-double-space t)
 #+END_SRC
