-Buffruneio is a wrapper around bufio to provide buffered runes access with
-unlimited unreads.
-
-```go
-import "github.com/pelletier/go-buffruneio"
-```
-
-## Examples
-
-```go
-import (
-    "fmt"
-    "github.com/pelletier/go-buffruneio"
-    "strings"
-)
-
-reader := buffruneio.NewReader(strings.NewReader("abcd"))
-fmt.Println(reader.ReadRune()) // 'a'
-fmt.Println(reader.ReadRune()) // 'b'
-fmt.Println(reader.ReadRune()) // 'c'
-reader.UnreadRune()
-reader.UnreadRune()
-fmt.Println(reader.ReadRune()) // 'b'
-fmt.Println(reader.ReadRune()) // 'c'
-```
