Great,

Since this could be generally useful would you be willing to add it to
the library of babel (org/contrib/babel/library-of-babel.org)?  If so
then if you could supply a few explanatory sentences, I'll add those and
the code block to the library-of-babel.org distributed with Org-mode.

Thanks -- Eric
