 gspell development
 ==================
-
-Contributions are no longer accepted
-------------------------------------
-
-And new maintainers are not accepted either.
-
-But the source code is open, you can copy it freely and create a new project.
-What I just ask for the new project:
-- Must have a different project name.
-- And it must be possible to install gspell plus the new project in parallel on
-  the same prefix. For example by just bumping the major/API version of the
-  library to something far apart.
-
-Notes
------
-
-gspell follows the same guidelines and code conventions as GtkSourceView (when
-GtkSourceView was still developed by Sébastien Wilmet).
