-----------------------------------------
{quote}How else would something like this be executed? Maybe I don't understand
your subsequent recommendation...\{quote}
can it just be a utility class that I call from a test or so I mean I am not
sure how userfriendly it is to specify classpaths etc. I'd just run it from a
test. I also think it's way more flexible if you have a java API to call rather
than some cmd args you need to parse etc.
{quote}Are you basically fine with me committing this?\{quote}
I think it should support deletes and should not use IW then I ok with it

> This issue introduces a MergePolicy simulator utility to help evaluate the
> effectiveness of a MergePolicy. The simulator does not result in the actual
> indexing and merging of segments; instead it provides some dummy constructs
> to MergePolicy to evaluate its decisions. Therefore you can do simulation
> runs in little time.
> I'm not sure where it would live. Perhaps dev-tools, or in tests, or in
> benchmark?
