in repository ruby-org.

commit 7354b5874f90862b6f76c0a7085d475b4940a0d6
Author: Rüdiger Sonderfeld <ruediger at c-plusplus.de>
Date:   Sat Jul 23 18:45:51 2011 +0200

    Convert special symbols (e.g., \alpha) to corresponding html or utf8 for textile.
    
    The replacement code is autogenerated from Emacs. The generated code is included because org-ruby should not require Emacs and org-mode for building. The generation is not added to Rake (yet) and you have to run it manually from Emacs.
