Hi, Sean

"nano-scale" was a pun, and also the idea I had of nano. I thought it was
called like that because nano is minimalistic. 

Your description is interesting. But I will stick with Emacs.

I'd like to add your Mercury mode and your custom formatter hook for nano to
the Mercury Resources List. I'd also like to add other useful projects of
yours. I'm a little lost in the 50 projects you have on Github. Could you
tell me the names of the projects you own, which you think are suitable for
adding to the list? I'll do the rest.

Cheers,
Volker
