30 * Convenience class for reading character files.  The constructors of this

32 * size are appropriate.  To specify these values yourself, construct an
33 * InputStreamReader on a FileInputStream.
34 *
35 * <p><code>FileReader</code> is meant for reading streams of characters.
36 * For reading streams of raw bytes, consider using a
37 * <code>FileInputStream</code>.
