+ * @file
+ *
+ * @description
+ *
+ * OpenStreetMap SlippyMap - MediaWiki extension
+ *
+ * This defines what happens when <slippymap> tag is placed in the wikitext
+ *
+ * We show a map based on the lat/lon/zoom data passed in. This extension
brings in
+ * the OpenLayers javascript, to show a slippy map.
+ *
+ * Usage example:
+ * <slippymap lat=51.485 lon=-0.15 z=11 w=300 h=200
layer=osmarender></slippymap>
+ *
+ * Tile images are not cached local to the wiki.
+ * To acheive this (remove the OSM dependency) you might set up a squid proxy,
+ * and modify the requests URLs here accordingly.
+ *
+ * This file should be placed in the mediawiki 'extensions' directory
+ * ...and then it needs to be 'included' within LocalSettings.php
