+/**
+ * This class defines the encoding half of character encoders.
+ * A character encoder is an algorithim for transforming 8 bit binary
+ * data into text (generally 7 bit ASCII or 8 bit ISO-Latin-1 text)
+ * for transmition over text channels such as e-mail and network news.
+ *
+ * The character encoders have been structured around a central theme
+ * that, in general, the encoded text has the form:
+ *
+ * <pre>
+ *      [Buffer Prefix]
+ *      [Line Prefix][encoded data atoms][Line Suffix]
+ *      [Buffer Suffix]
+ * </pre>
+ *
+ * In the CharacterEncoder and CharacterDecoder classes, one complete
+ * chunk of data is referred to as a <i>buffer</i>. Encoded buffers
+ * are all text, and decoded buffers (sometimes just referred to as
+ * buffers) are binary octets.
+ *
+ * To create a custom encoder, you must, at a minimum,  overide three
+ * abstract methods in this class.
+ * <DL>
+ * <DD>bytesPerAtom which tells the encoder how many bytes to
+ * send to encodeAtom
+ * <DD>encodeAtom which encodes the bytes sent to it as text.
+ * <DD>bytesPerLine which tells the encoder the maximum number of
+ * bytes per line.
+ * </DL>
+ *
+ * Several useful encoders have already been written and are
+ * referenced in the See Also list below.
+ *
