whats the difference between commit & deliver

there are two events being sent in IWorkspaceConnection, ICommitEvent.COMMIT and IChangeHisotryEvent.DELIVER. Whatexactly is the difference? Normally I can only see the deliver event

Is it possible that the COMMIT event will only be sent when I am connecting to CVS/SVN, as described here: https://jazz.net/learn/LearnItem.jsp?href=content/docs/source-control/faq/index.html?

Commit means changes were committed to a changeset in that workspace.
Deliver means a set of changesets/baselines have been delivered to
another workspace.

No, commit happens all the time, it is how you build up changesets.
