Thanks, a couple of comments below.

This talks about precedence between the variable and the command-line
option without first introducing the environment variable. The
precedence part should be not _instead_ of the description of the
variable, but _in_addition_ to it. It's okay that there's now the
ENVIRONMENT section, but it's too far away, so at least something like
"see ENVIRONMENT below" should be here.

Same here.

And here.

And here.

And this section should say that the corresponding command-line
arguments override the environment variables.
