 The GMap Macro Builder is a GUI for creating GMap macros; you may use it to create a map with points, lines, polygons, and circles, and then copy and paste the resulting macro text. After you insert the macro into a node, you can edit it using raw values that you get from elsewhere to create a different set of points or lines on the map.
 
 If you've enabled the gmap_macro_builder.module, you can access the GMap macro builder at the 'map/macro' path (there will be "Build a GMap macro" link in your Navigation menu).
 
-Note that there are many more options you can set on your maps if you are willing to edit macros by hand. For example, you may add KML or GeoRSS overlays to GMaps, but this option isn't available through the macro builder. Again, see API.txt for syntax details.
