All Implemented Interfaces:

Closeable, AutoCloseable, Readable
```
public class ReadlineReader
extends Reader
```
A Reader wrapper for the Readline classes. This seems to work fine in conjunction with such classes as BufferedReader, but it hasn't been tested well enough to see if this will work well in all cases. This was implemented to make it easier to supplant Readline's functionality [shrug] anywhere and everywhere, but specifically in BeanShell.
