iw.releaser consists of 3 parts (the doc is outdated) :

- an entry point for setuptools to add a release command for eggs. This
helps developer
  release one package. but it is just a tool to help releasing.
- a project_release script, that create a svn branch for a buildout
- a project_deploy that runs bootstrap, bin/buildout then creates a tarball
  this is the part that does like zc.sourcerelease (see
https://ingeniweb.svn.sourceforge.net/svnroot/ingeniweb/iw.releaser/trunk/iw/releaser/project.py)
afaik
