This page has been labelled for deletion.
The given reason is: Kosmos has been depreciated for Maperitive. Therefore pages about it and usage rules are no longer valid. Since it is no longer available. Therefore they are being purged as a part of a cleanup project.
This normally means the page title is a bad one, and the content has been moved somewhere better. If a page title is vaguely meaningful, the page should perhaps be a redirect, or hold a small summary for historical interest instead. If you disagree with its deletion, please explain why on its talk page.
The page should now be empty apart from this message (as per procedure). The page history shows what used to be on this page, and allows people to rescue an old revision. We may decide to do this, but otherwise a wiki sysop user can delete this page more permanently at some point. In the meantime we should fix any pages linking to here.
