The goal of this package is to be a drop-in replacement for the diffutils commands (diff, cmp, diff3, sdiff) in Rust.

Based on the incomplete diff generator in https://github.com/rust-lang/rust/blob/master/src/tools/compiletest/src/runtest.rs, and made to be compatible with GNU's diff and patch tools.
