source code

/**
* This class implements a technical support system. It is
* the top-level class in this project. The support system
* communicates via text input/output in the text terminal.
* This class uses an object of class InputReader to read
* input from the user and an object of class Responder to
* generate responses.
* It contains a loop that repeatedly reads input and
* generates output until the user wants to leave.
