expect - programmed dialogue with interactive programs

Expect  is a program that "talks" to other interactive programs according to a script.  Following  the  script, Expect  knows  what  can  be expected  from  a  program and what the correct response should be. 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.
