Hello, thank you for this great crate. I just want to point out that there is no example to show that you can configure multiple crates in a row with a comma:

RUST_LOG = "data=debug,hardware=debug"

Also, I lost a lot of time because I had a crate called fan-control, and the correct name to configure it was fan_control, I think it would be good to mention it in the docs.

Thanks

Technically we do describe this syntax

The value of this environment variable is a comma-separated list of logging directives.

but that is easy to miss and showing it in the syntax, maybe with an example, could help.

Oh, looks like we do have examples at the end of the section. Making tweaks to hopefully catch people's eye more.
