message: Add mention of disabling benchmarks in binaries as well as libraries. Fixes
diff: @@ -64,6 +64,19 @@ for library crates, you could add this to your `Cargo.toml` file:
  bench = false
  ```
  +If your crate produces one or more binaries as well as a library, you may need to add additional
  +records to `Cargo.toml` like this:
  +
  +```toml
  +[[bin]]
  +name = "ny-binary"
  +path = "src/bin/my-binary.rs"
  +bench = false
  +```
  +
  +This is because Cargo automatically discovers some kinds of binaries and it will enable the default
  +benchmark harness for these as well.
  +
  Of course, this only works if you define all of your benchmarks in the
  `benches` directory.
