A program that can automate interactive applications
Expect is a tool for automating interactive applications according to a script.
Following the script, Expect knows what can be expected from a program and what
the correct response should be. Expect is also useful for testing these same
applications. And by adding Tk, you can also wrap interactive applications in
X11 GUIs. An interpreted language provides branching and high-level control
structures to direct the dialogue. In addition, the user can take control and
interact directly when desired, afterward returning control to the script.
