> Some stages were submitted. I'm not sure where they should go. Maybe SessionStage and
CommitStage could go under
>     package org.apache.commons.pipeline.stage.contrib.hibernate;
> and GroupStage and UngroupStage could go into
>     package org.apache.commons.pipeline.stage.contrib;
> I've looked over the code but haven't run these yet. These are here so people can work
with them and comment on improvements and how to add them to the pipeline codebase.

if I might contribute back a few Stages that I've written? The first two have dependencies
on commons-collections and the last two on Hibernate. Maybe they could go into a user-contrib
project?
