 /**
  * Encodes and decodes to and from Base64 notation.
- *
+ * 
  * <p>
  * Change Log:
  * </p>
  * <ul>
- *  <li>v2.1 - Cleaned up javadoc comments and unused variables and methods. Added
- *   some convenience methods for reading and writing to and from files.</li>
- *  <li>v2.0.2 - Now specifies UTF-8 encoding in places where the code fails on systems
- *   with other encodings (like EBCDIC).</li>
- *  <li>v2.0.1 - Fixed an error when decoding a single byte, that is, when the
- *   encoded data was a single byte.</li>
- *  <li>v2.0 - I got rid of methods that used booleans to set options. 
- *   Now everything is more consolidated and cleaner. The code now detects
- *   when data that's being decoded is gzip-compressed and will decompress it
- *   automatically. Generally things are cleaner. You'll probably have to
- *   change some method calls that you were making to support the new
- *   options format (<tt>int</tt>s that you "OR" together).</li>
- *  <li>v1.5.1 - Fixed bug when decompressing and decoding to a             
- *   byte[] using <tt>decode( String s, boolean gzipCompressed )</tt>.      
- *   Added the ability to "suspend" encoding in the Output Stream so        
- *   you can turn on and off the encoding if you need to embed base64       
- *   data in an otherwise "normal" stream (like an XML file).</li>  
- *  <li>v1.5 - Output stream pases on flush() command but doesn't do anything itself.
- *      This helps when using GZIP streams.
- *      Added the ability to GZip-compress objects before encoding them.</li>
- *  <li>v1.4 - Added helper methods to read/write files.</li>
- *  <li>v1.3.6 - Fixed OutputStream.flush() so that 'position' is reset.</li>
- *  <li>v1.3.5 - Added flag to turn on and off line breaks. Fixed bug in input stream
- *      where last buffer being read, if not completely full, was not returned.</li>
- *  <li>v1.3.4 - Fixed when "improperly padded stream" error was thrown at the wrong time.</li>
- *  <li>v1.3.3 - Fixed I/O streams which were totally messed up.</li>
+ * <li>v2.1 - Cleaned up javadoc comments and unused variables and methods.
