Docs.rs uses semver to parse URLs. You can use this feature to access
            crates' documentation easily. Example of URL redirections for
            clap crate:
        
| URL | Redirects to documentation of | 
|---|---|
| docs.rs/clap | Latest version of clap | 
| docs.rs/clap::Command | Latest version of clap, and search for "Command" within the crate | 
| docs.rs/clap/~2 | 2.* version | 
| docs.rs/clap/~2.9 | 2.9.* version | 
| docs.rs/clap/2.9.3 | 2.9.3 version (you don't need =unlike semver) | 
| docs.rs/clap/* | Latest version of this page (if it still exists). "latest" or "newest" work as well as *. |
