The Infobox for Maps is a simple way of summarizing information on a map.

Syntax

{{Infobox Map
| name = Dude's cool map
| author = Dude
| image = dudes_cool_map.jpg
| image_caption = Look at Dude's cool map!
| link = [http://link.to/dudes/cool.map]
}}

Only the name parameter is mandatory but if that's the only one you probably don't want an Infobox, just a heading.

The link parameter is not post-processed to allow for multiple links.
