Do you want to abort if SPACK_ENV is not set, i.e. make it a requirement?

I think that's what this will do? If not then I can explicitly set set -a or whatever to fail on non-zero.

set -e I think - I was confused because the notes above say "it is strongly recommended" to do this in an active env.

Also add to doc/source/? |

I resolved the conflict, once the readthedocs page is rendered I'll take a look, if it looks good I'll merge |
Summary
This PR adds a utility for doing single-node parallel installations using backgrounded instances of
spack install. Mostly suitable for small installations or interactive batch jobs; for larger installations using a batch job along the lines of what we have for Acorn probably makes more sense.Testing
Tested on personal machine.
