-    GDAL version 1.9.1 or greater with cURL support enabled.  
-
-    To check if cURL is enabled for GDAL, use the command `gdalinfo --format WMS`  
-    If cURL is enabled you will see information about the WMS format, if not, 
-    you will get an error message and you will need to reconfigure GDAL to support cURL.  
-    **NOTE:** If this comes with your Anaconda distribution of Python, you may need
-    to set an environmental variable called GDAL_DATA in your bash profile that points to
-    gdal within your Anaconda folder.
