+A crate for stripping ANSI escape sequences from byte sequences.
+
+This can be used to take output from a program that includes escape sequences and write
+it somewhere that does not easily support them, such as a log file.
+
+# Examples
+
+The `strip` function accepts bytes and returns a `Vec` of bytes with ANSI escape sequences removed.
+
+```rust
+extern crate strip_ansi_escapes;
+
+use std::io::{self, Write};
+
+fn work() -> io::Result<()> {
+  let bytes_with_colors = b"\x1b[32mfoo\x1b[m bar";
+  let plain_bytes = strip_ansi_escapes::strip(&bytes_with_colors)?;
+  io::stdout().write_all(&plain_bytes)?;
+  Ok(())
+}
+
+fn main() {
+    work().unwrap();
+}
+```
+
+For writing directly to a writer, the `Writer` struct may be preferable.
+
+```rust
+extern crate strip_ansi_escapes;
+
+use std::io::{self, Write};
+use strip_ansi_escapes::Writer;
+
+fn work() -> io::Result<()> {
+  let bytes_with_colors = b"\x1b[32mfoo\x1b[m bar";
+  let mut writer = Writer::new(io::stdout());
+  // Only `foo bar` will be written to stdout
+  writer.write_all(bytes_with_colors)?;
+  Ok(())
+}
+
+fn main() {
+    work().unwrap();
+}

+//! This can be used to take output from a program that includes escape sequences and write

+//! The simplest interface provided is the [`strip`] function, which takes a byte slice and returns
