Yes, you configure what file it should use to collect modified
environment variables (called `buffer-env-script-name'), and then
depending on the file name it will run a command. E.g. if you want to
use manifest.scm files and a manifest.scm file is found, it will run
guix shell -D -f \"path/to/mainfest.scm\" -- env -0

No, instead it just looks for the guix.scm or manifest.scm file in a
"dominating directory" (the current working directory or anything
above). Project.el integration would be trivial to add though.

I wrote about it in some more detail here:

attract much attention.
