`Tranformers' define tranformations of Strings, byte arrays and streams.
Transformers are devided in three species. CharTransformers which transform some String to
another String (or Reader to a Writer). Then there are transformation which take a byte array
(or an InputStream) and transform that to a String (or a Writer), these are called
ByteToCharTransformers. And the last type are are the ByteTranformers, which tranform a byte
array to another byte array (or an InputStream to an OutputStream).
All Transformers can be specialized to 'ConfigurableTransformers'.
Several Abstract implemenations are present too. E.g. the 'ReaderTransformer' is nearly a
complete CharTransformer, only the function wich pipes a Reader to a Writer is
abstract. StringTranformer is a CharTransformer which' only abstract function is the one
taking a String argument.

| Java Source File Name | Type | Comment |
| AbstractCommandStringTransformer.java | Class | If you want to transform a Reader stream by the use of an external command, than you can extend
this class. |
| Base64.java | Class | |
| BufferedReaderTransformer.java | Class | |
| ByteArrayToCharTransformer.java | Class | You need only to implement transform(byte[]) you have the simplest
kind of transformer (which is not 'streamable'). |
| ByteCharTransformer.java | Class | A CharTransformer which wraps a ByteToCharTransformer. |
| ByteToCharTransformer.java | Interface | Interface for transformations. |
| ByteTransformer.java | Interface | Interface for transformations. |
| Censor.java | Class | Replaces certain 'forbidden' words by something more decent. |
| ChainedCharTransformer.java | Class | A CharTransformer which wraps N other CharTransformers, and links them with N - 1 new Threads,
effectively working as a 'chained' transformer.
The first transformation is done by the ChainedCharTransformer instance itself, after starting
the N - 1 Threads for the other N - 1 transformations.
If no CharTransformers are added, and 'transform' is called, logically, nothing will happen. |

Transformer instances, but can do that
'parameterized'. |
| Perl.java | Class | And yet another rather idiotic type of Transformer. |
| ReaderTransformer.java | Class | You need only to implement transform(Reader, Writer) you have the simplest
