Subject: Explain what to do if test vectors are missing
X-Git-Url: https://git.codecow.com/?a=commitdiff_plain;h=164d7de5531256a10f464bd8ba56831f3ec7e46c;p=Monocypher.git

Explain what to do if test vectors are missing

Users who try to `make test` without the test vectors will have a nice
error message explaining how to actually perform the tests (either
generate those test vectors, or grab an official release.

It should thus be clear what libsodium is for, and why end users don't
need it.
