+# This is the script for us to try to cause the TDengine server or client to crash
+#    
+# PREPARATION
+#
+# 1. Build an compile the TDengine source code that comes with this script, in the same directory tree
+# 2. Please follow the direction in our README.md, and build TDengine in the build/ directory
+# 3. Adjust the configuration file if needed under build/test/cfg/taos.cfg
+# 4. Run the TDengine server instance: cd build; ./build/bin/taosd -c test/cfg
+# 5. Make sure you have a working Python3 environment: run /usr/bin/python3 --version, and you should get 3.6 or above
+#
+# RUNNING THIS SCRIPT
+# 
+# This script assumes the source code directory is intact, and that the binaries has been built in the
+# build/ directory, as such, will will load the Python libraries in the directory tree, and also load
+# the TDengine client shared library (so) file, in the build/directory, as evidenced in the env
+# variables below.
+#
+# Running the script is simple, no parameter is needed (for now, but will change in the future).
+#
+# Happy Crashing...
+
+
+# Due to the heavy path name assumptions/usage, let us require that the user be in the current directory
+EXEC_DIR=`dirname "$0"`
+if [[ $EXEC_DIR != "." ]]
+then
+    echo "ERROR: Please execute `basename "$0"` in its own directory (for now anyway, pardon the dust)"
+    exit -1
+fi
+
+# First we need to set up a path for Python to find our own TAOS modules, so that "import" can work.
+export PYTHONPATH=$(pwd)/../../src/connector/python/linux/python3
+
+# Then let us set up the library path so that our compiled SO file can be loaded by Python
+export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$(pwd)/../../build/build/lib
+
+# Now we are all let, and let's see if we can find a crash.
