Forwarding FYI. I'm pretty sure this is an area that interests a lot of you.
For those interested please feel free to come and discuss it on the cargo
lists.

Hi Cargo devs,

Juri has started working on this. I've committed his work in the
contrib/customizer/ area
(https://svn.codehaus.org/cargo/cargo/trunk/contrib/customizer/).

The idea is for all of you to provide input. I didn't get much feedback on
the proposal below... :-)

I believe this is going to be big as there's real need for packaging J2EE
archives depending on an environment. There's currently no neat solution for
any build tool (ant, maven1, maven2) that I know of.

The idea is to offer this feature in Cargo. 

So if you're using maven1 or maven2 for example you'll be able to have your
normal build that builds your modules independently of any environment and
then have an environment module which will repackage your artifacts and
modify their contents depending on your environments.

There are still a lot of work to be done and we need all possible inputs and
help.

Thanks
-Vincent
