+The pickling-section may be a bit tricky so that I included simpler test scripts in this directory (pickle-test-scripts/) to check if your environment is set up correctly. Basically, it is just a trimmed-down version of the relevant sections from Ch08, including a very small movie_review_data subset.
+
+Executing
+
+    python pickle-dump-test.py
+
+will train a small classification model from the `movie_data_small.csv` and create the 2 pickle files 
+
+    stopwords.pkl
+    classifier.pkl
+
+Next, if you execute
+
+    python pickle-load-test.py
+
+You should see the following 2 lines as output:
+
+    Prediction: positive
+    Probability: 85.71%
