automatic @version tag generation

The "How to Write Doc Comments for the JavadocTM Tool" document

(http://java.sun.com/j2se/javadoc/writingdoccomments/index.html)

talks about taking the version from the version control system at

check out, using something like this:

@version %I%, %G%

Is this an automatic operation or is supposed to be manual?

I was wondering if anyone knows how to automate this process for ClearCase and/or CVS.

Thanks
