[ELPA] new package: tramp-docker

[Brian Cully]

This package allows Tramp to use Docker (and Podman) containers as its 
remote environment.

Note that there is an extant 'docker-tramp' module in MELPA, so there 
may be some confusion. I wrote this one in order to get it into ELPA, 
and, as such, I've assigned copyright to the FSF.

The repository lives at: https://git.spork.org/tramp-docker.git

Docker is a big enough target that it may be worth integrating this 
directly in Emacs rather than going through ELPA. I'm not currently set 
up to do this, but if anyone wants to integrate it and submit it 
upstream, you have my blessing.
