Hi,

I'm spending a lot of time in org-mode doing literate programming and it
does most everything that I need.

However, it did not support the jison
<http://zaach.github.io/jison/try/> compiler
generator.  So I added it by copying ob-dot.el and making some minor
changes. I also wrote instructions that more or less follow the same
outline as the dot documentation
<http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-dot.html>.

If this patch is added to org-mode then org-babel will have a language for
making new languages.

Thanks,

Peter
