-# pty
-
-Pty is a Go package for using unix pseudo-terminals.
-
-## Install
-
-    go get github.com/creack/pty
-
-## Example
-
-### Command
-
-```go
-package main
-
-import (
-	"github.com/creack/pty"
-	"io"
-	"os"
-	"os/exec"
-)
-
-func main() {
-	c := exec.Command("grep", "--color=auto", "bar")
-	f, err := pty.Start(c)
-	if err != nil {
-		panic(err)
-	}
-
-	go func() {
-		f.Write([]byte("foo\n"))
-		f.Write([]byte("bar\n"))
-		f.Write([]byte("baz\n"))
-		f.Write([]byte{4}) // EOT
-	}()
-	io.Copy(os.Stdout, f)
-}
-```
-
