Added: jelly/src/java/org/apache/commons/jelly/util
NestedRuntimeException.java
Log:
Added the new Threads library created by Jason Horman which allows simple and
complex threading to be used inside a Jelly script.
This is especially useful for evaluating different Jelly scripts in parallel and
then joining them back together.
