Hi. I could try to do this if you want.

I have already done it, but not sure if this the idea.

Doubts about position/formatting:

• Should it be first/latest print better? I guess versioning it's used to be shown as the first or latest thing on the output, but...

./target/debug/sccache --show-stats

Yes! This is what I want.

Showing along with cache location LGTM. In the future, maybe we can introduce sections like setup and statistics to make them more readable.

For the output content, we can remove the Sccache prefix, and only use Version.

There should be a clear indicator that it's the client version.

Do you mean something like this explicitly?

Or even some kind of concat like

....
Version              0.4-pre.6 (client)

Thanks.
