Org - mode was created by Carsten Dominik in 2003 , originally to organize his life and work , and since the first release numerous users and developers have contributed to this free software package , Emacs includes Org - mode as a major mode . Bastien Guerry is the current maintainer , in cooperation with an active development community . Since its success in EMACS , some other systems have also begun providing functions to work with org files . - Emacs and its derivatives are a family of text editors that are characterized by their extensibility.
