/* 

 An Albers Equal Area Conic projection in javascript, for protovis.

 For centering the contiguous states of the USA in a 800x400 div, I used:

 var scale = pv.Geo.scale(albers(23, -96, 29.5, 45.5))
                .range({ x: -365, y: -375 }, { x: 1200, y: 1200 });

  As of version 1.1.2, Propane will load and execute the contents of

  You can use this mechanism to add your own customizations to Campfire

  Below you'll find two customization examples.

Building GDAL 1.9.x with ESRI FileGDB support on OS X Lion

• Download the SDK from ESRI's website http://resources.arcgis.com/content/geodatabases/10.0/file-gdb-api
• Extract the SDK, and put the contents of the directory in a known location, I used ~/local/filegdb. Here's an example path to one of the files: ~/local/filegdb/lib/libFileGDBAPI.dylib
• I use ~/local/filegdb so it can stay isolated in it's own place. You can put it anywhere, but the next few steps might be different.
• Go into the directory containing the FileGDB SDK, e.g. ~/local/filegdb
• ESRI built these dylib's using @rpath's, so to avoid needing to mess with DYLD_LIBRARY_PATH, I updated the @rpath's using install_name_tool. There might be a more elegant way to handle this. If so, comments are welcome!
• Here are the commands I used to patch the dylibs, this is not required if you want to use DYLD_LIBRARY_PATH yourself:
