[INFO] [stderr] The bin target `cargo-ebuild` in package `cargo-ebuild v0.3.1 (/opt/rustwide/workdir)` has the same output filename as the lib target `cargo_ebuild` in package `cargo-ebuild v0.3.1 (/opt/rustwide/workdir)`.
[INFO] [stderr] Colliding filename is: /opt/rustwide/target/doc/cargo_ebuild/index.html
[INFO] [stderr] The output filenames should be unique.
[INFO] [stderr] This is a known bug where multiple crates with the same name use
[INFO] [stderr] the same path; see <https://github.com/rust-lang/cargo/issues/6313>.
