 This is an attempt to implement an API to create, update or delete DNS records
 on a BIND9 DNS server.

-
-To compile the code, you first need to [install Rust](https://rustup.rs/). Then
-you can run
-
-```
-cargo build --release

-
-in the project root. The server and client binary will be located in
