-You will need `clang` and `clang++` along with basic build dependencies for this example to compile.
-To build this example, run `cargo build --example libfuzzer_libpng --release`.
-This will call [the build.rs](./build.rs), which in turn downloads a libpng archive from the web.

-Afterwards, the fuzzer will be ready to run, from `../../target/examples/libfuzzer_libpng`.
-=======
 To build this example, run `cargo build --release`.
 This will build the library with the fuzzer (src/lib.rs) with the libfuzzer compatibility layer and the SanitizerCoverage runtime functions for coverage feedback.
 In addition, it will build also two C and C++ compiler wrappers (bin/c(c/xx).rs) that you must use to compile the target.
