 * This is where this extension originated see 'Slippy Map MediaWiki Extension' page. Currently forked a version of the code in the OSM repo, but trying to re-sync (and swap to using the new syntax)
 * 
 * Just to let others know where you live, or feed them misinformation... e.g.: Betawiki:User:Raymond/Kölner_Dom. Newish version (latest syntax)
 * Fürthwiki
 * We use OSM & SlippyMap whenever we describe streets, important buildings or sights: (old version old syntax)

Syntax
The extension allows users to embed a slippy map using the following syntax in their wiki code:



Older version (running on the above sites) took a syntax like this:

lat=51.485|lon=-0.15|z=11|w=300|h=200|format=jpeg

Users can discover suitable latitude logitude and zoom values by doing the following:
 * Edit the page
 * Use the slippymap syntax with any old values e.g. paste in the above example
 * Doing a preview
 * zoom/pan the right position,
 * Use the 'Get wikicode' button
 * Copy and paste the resulting wiki code into the editing box
 * Save the page

TODO

 * support multiple maps on one wiki page
 * fix js embedding include method
 * internal marker image
 * config option to enable/disable
 * MapOfService
 * a layer
 * make get "Get wikicode" button marker aware
 * Change syntax to be in line with Extension:Google Maps
