It's a good idea to point to the website, but help for the -h flag is not the right place for it. Add it as a line in usage() call maybe?

Add it a line in usage() call maybe?

maybe not.

• The (smart) user is looking for help and asks for help (with --help).
• Triggering usage message on demand is hard, surely no intuitive as -h.
• The truly helpless user is already adviced to do cargo deb --help.

Screenshot:

$ cargo deb foo
error: unexpected argument 'foo' found

Usage: cargo build [OPTIONS]

For more information, try '--help'.
cargo-deb: build failed

$ cargo deb usage
error: unexpected argument 'usage' found
