Re: [ANNOUNCEMENT] Test: coreutils 9.0 (TEST)

[Keith Christian <keith1christian@gmail.com>]

I'd like to test coreutils but cannot find the docs for how to install
a test version.
Sorry, but I don't see anything in setup.exe that would facilitate
installing a test version, seems I recall that test versions were
available to install via setup.
