+The Nearest Neighbor application computes the nearest location to a specific 
+latitude and longitude for a number of hurricanes (data from: http://weather.unisys.com/hurricane/).
+
+The Makefile may need to be adjusted for different machines, but it was written for Mac OS X and
+Linux with either NVIDIA or AMD OpenCL SDKs.
+
+The hurricane data is located in a number of data files that are copied into the working
+directory by the Makefile.  A separate text file lists the names of the data files that
+will be used, and it is this text file that should be passed to the application (see usage, below).
+
+Nearest Neighbor Usage
+
+nearestNeighbor [filename] -r [int] -lat [float] -lng [float] [-hqt] [-p [int] -d [int]]
+
+example:
+$ ./nearestNeighbor filelist.txt -r 5 -lat 30 -lng 90
+
+filename     the filename that lists the data input files
+-r [int]     the number of records to return (default: 10)
+-lat [float] the latitude for nearest neighbors (default: 0)
+-lng [float] the longitude for nearest neighbors (default: 0)
+
+-h, --help   Display the help file
+-q           Quiet mode. Suppress all text output.
+-t           Print timing information.
+
+-p [int]     Choose the platform (must choose both platform and device)
+-d [int]     Choose the device (must choose both platform and device)
+
+
+Notes: 1. The filename is required as the first parameter.
+       2. If you declare either the device or the platform,
+          you must declare both.
