Make a builder

To create a new builder like a the MarkupBuilder or AntBuilder, you have to implement in java (in groovy later too) a subclass of the groovy.util.BuilderSupport class.
The main methods to be implemnted are the following :

• protected abstract void setParent(Object parent, Object child);
• protected abstract Object createNode(Object name);
• protected abstract Object createNode(Object name, Object value);
• protected abstract Object createNode(Object name, Map attributes);
• protected abstract Object createNode(Object name, Map attributes, Object value);
• protected Object getName(String methodName)
