In the exercise sessions, the students will have a chance to use the tools that are described in the lectures. They will work with CVS and configuration management tools. They will be asked to use the test and debugging tools on some simple examples. By showing how these tools can locate known problems, students will learn how to use them on new problems. Students will then be given a functional program and a brief description of what it does. The goal is to extend the program to handle a larger problem domain. It is expected that the example programs and exercises will be primarily in C++. In the final exercise sessions, the students will practice the new technologies introduced with examples. For these exercises the Python language will be used.
