[Glenn McDonald]

Running the command specified in the readme in go version go1.16.5 linux/amd64:

go get github.com/clever/microplane/cmd

yields the following error message:

go: downloading github.com/clever/microplane v0.0.32
go get: github.com/clever/microplane@v0.0.26 updating to
        github.com/clever/microplane@v0.0.32: parsing go.mod:
