 KMeans Classifier Implementation
 
-Example:
-  # generate test data with 1000 rows clustered around 3 points
-  ./gen-data.rb 1000 3 > example.dat
+Examples:
 
-  # classify data, plot results as png
-  ./km-test kmeans example.dat example.png
+Generate 1000 rows of test data, clustered around 3 points:
+
+    # generate test data
+    ./gen-data.rb 1000 3 > example.dat
+
+    # classify data, plot results as png
+    ./km-test kmeans example.dat example.png
+
+Run all tests and save best clustering in current directory along with
+PNGs of results:
+
+    for i in tests/*dat; do
+      # build paths
+      png_path=kmeans-$(basename ${i/dat/png})
+      dst_path=kmeans-$(basename $i)
+
+      # run test
+      echo $i
+      ./km-test kmeans $i $png_path > $dst_path
+    done
