[Rust] Packaging help

[Jim Campbell]

Hello Fedora Rust people,

I am interested in packaging Rust applications in Fedora. I think it would
be good for me to start by updating packages that are already present in
the repos rather than bringing in new applications.

Where would be a good place for me to start, and are there restrictions
around updating packages in already-released Fedora versions?

Thanks, and I'll look forward to working with you,

Jim
