Does Alchemy Support Versions, workflow, tags, search - i.e., stuff outside of content but not layout

[Mike Papper]

Im reading about Alchemy. I sort of understand the content storage and push that into a pre-made layout (made by a developer).
But I cannot tell if it has support for all the stuff that "surrounds" content management - like versions of content, workflow (where you pass content through people before its published), tags and search?

Is there a page with a feature set?

Any input is appreciated.
