[INFO] [stderr] warning: An explicit [[example]] section is specified in Cargo.toml which currently
[INFO] [stderr] disables Cargo from automatically inferring other example targets.
[INFO] [stderr] This inference behavior will change in the Rust 2018 edition and the following
[INFO] [stderr] files will be included as a example target:
[INFO] [stderr] 
[INFO] [stderr] * /opt/crater/workdir/examples/json.rs
[INFO] [stderr] * /opt/crater/workdir/examples/debug.rs
[INFO] [stderr] 
[INFO] [stderr] This is likely to break cargo build or cargo test as these files may not be

[INFO] [stderr] and disable this warning by adding `autoexamples = false` to your [package]
