ELPA: where is chess developed?

[Jack Hill]

Hi Emacs,

I'm interested in working with the Chess package. According to 
1b67906a62fe84cf838f7bb88675af69e0efff13 [0], Chess is developed in the 
the main ELPA repository. However, it seems that the previous upstream 
location [1] has seen more development activity than the external/chess 
branch [2].

[1] https://github.com/jwiegley/emacs-chess
[2] https://git.savannah.gnu.org/cgit/emacs/elpa.git/log/?h=externals/chess

What's going on here? Did the project fork and there are two development 
streams going forward? Did the aspiration to develop chess in the ELPA 
repository fail, and we should switch back to jwiegley/emacs-chess as 
upstream? If I package this for my distribution, which one should I use?

Please copy me on replies.

Thanks,
Jack
