The map manager was originaly created by baba. We made some slight changes to it but as far as I know the original version is still under development. I believe baba plans to release it for public release once it's 100% complete. I was asked not to release it to anyone so I'm unable to give it to you. Plus it's pretty buggy right now and the adverage user would prolly not even beable to install it. So it would be best to wait for the final version of it anyway.
