pub fn write_man(out: &mut impl Write) -> Result<(), CliError>Expand description
Writes the roff source of acme-proxy.1.
Rendered section by section rather than through Man::render, because
three of them are facts clap has no way to know: the environment this
binary reads, the file it looks for, and where the full documentation is.
They are written as roff here rather than hung off after_long_help, which
would put the same block — .TP markup and all — into --help.
One page, for the top-level command. The per-flag detail of every subcommand
lives in the book’s Admin CLI chapter, which SEE ALSO names: a tree of ~50
roff files would document admin user totp reset for a binary that installs
no man pages at all.
