@atenjin The commit hash is missing in the second command here:

$ cargo run -- --version
cargo-contract 0.8.0-bd0db50-x86_64-linux-gnu
$ cargo run -- contract --version
cargo-contract 0.8.0

Besides that I think it's fine the way you copied the generate_cargo_keys stuff, avoiding polluting the codebase with substrate-named environment variables. So you can remove the comments regarding that.

I would prefer not having a wildcard import here.

Suggested change

	use platforms::*;
	use platforms::{TARGET_ARCH, TARGET_ENV, TARGET_OS};

thanks, I find out the place to add version for this tip.

Now I have removed the todo command and added suitable version hint.
