This is true as far as I know, but it seems that Vaclac took it in
his own hands to code the initial stages and he checked it into the
GRASS 7.1 source.

I installed GRASS 7.1 from source using homebrew (the formula is in a
pending pull request) and I could execute the examples fine.

is working, but I don't know if it has been tested a lot. For testing,
the sp collection could help as there are already examples which one
could run.

Otherwise - no idea - but it seems to be going forward.

Yes - some changes and getting rid of the initialisation of the GRASS
session, and only provide the path to the grass71 executable.

--8<---------------cut here---------------start------------->8---
grass71 --exec g.list --interface-description
--8<---------------cut here---------------end--------------->8---

I just tried it out.

or, maybe safer,

--8<---------------cut here---------------start------------->8---
grass71 PATH/TO/MAPSET --exec g.list --interface-description
--8<---------------cut here---------------end--------------->8---

This is only the first stage, and Vaclac seems to be very much open to
suggestions and discussion on which direction this should go.

The discussion is on grass-user.

It seems that you are planning to move the sp packages to github - is
this true?
