It would be so helpful if a jar-versions.xml file could be kept up to date in the root of the seam source code to track the versions of the bundle libraries, in the absence of other solutions. This idea comes from the JBoss AS, which uses this file to communicate the versions of libraries used.
Documenting the versions helps:
1. developers, who may find challenge in combining APIs of libraries without knowing the version
2. users who are unable to determine the contents of what they downloaded
3. for legal reasons, just in case there are differences in licenses amongst releases of third party products, to protect seam itself as well as integrators of seam.
With all that said, the better solution is to use ant-ivy or maven2 to get the jar files out of the source code. But I digress.
