The following scenario should be supported:
1) The user starts engine using JNLP/bundled installer/media installer/etc
without any additional parameteres
2) The extra page should be available at the end of installation where the user
can create a one-file bundle with all the components that (s)he has installed or
the state file that (s)he could use for silent installation later.
How does it intersect with current -silent mechanism ?
I`d say it is a totally different thing.
