- top level tasks
- uses SAX2
- stateless handlers ( i.e. all 'state' is in AntContext, all handlers
are singletons ).
- automatically replaces ProjectHelper using the discovery ( i.e. just
place ant-sax2.jar in lib, and ProjectHelper2 will be used )
- uses PropertyInterceptor ( if any registered ) before looking in the 
properties hashtable
- import via Import task
- <systemPath> allows you to add dynamically a <path> to ant/lib
( like junit.jar ) and make optional tasks work with this one.

Just like the old one :-) I just did a bit of refactoring to 
make it stateless ( no for performance, but because I think it 
is much easier to have access to the whole state - including
element stack, file stack, etc )

What do you mean ? 

So far it builds the same files as gump ( i.e. with ProjectHelper2
I build the same set of projects as normal ant ). 

I'll add a sample for import and systemPath, and soon a BSF and JXPath

cleanups, samples/docs and that's it. I don't expect much change to 
the code.

The dynamic properties are 'plugged' by regular tasks - and 
import is also a regular task, etc. 

I am trying to elminate the special treatment of DataTypes/Tasks - 
there is some complexity there that I feel can be eliminated, but
not sure how to do it without braking something.

Give me few more days for this one.
