                        DefineJellyBeanTag.java DefineBeanTag.java
                        DefineTagTag.java DefineScriptTag.java

               jelly/src/java/org/apache/commons/jelly/impl BeanTag.java
  Log:
  modified the class names of the define tag library so that the autogenerated tag reference is accurate and the runtime (dynamic) implementaiton tags don't appear in the reference documentation.
  
  Also tidied up the javadoc to make the reference a little more complete for the define library
