Thanks so much for this. Moving all the Clap stuff out of main.rs feels great!

I do have some basic questions. I would have thought that, after cargo installing this version, I could then run man phraze and get a man page of documentation. However, I get back No manual entry for phraze. I am doing something silly?

You can test the man pages with man --local-file target/man/phraze.1 and the shell completions with source ./target/completions/<your_shell>.

Don't think it's possible to make this work with cargo install but package maintainers will be able to add it to their phraze packages.

Got it -- makes sense. But anything to make life easier for package maintainers I'm all for. Thanks again -- merged, and a new release (v0.3.13) on the way!
