The Expect for Perl module was inspired more by the functionality the Tcl tool provides than any previous Expect-like tool such as Comm.pl or chat2.pl. I've had some comments that people may not have heard of the original Tcl version of Expect, or where documentation (book form) on Expect may be obtained. The Tcl version of expect is a creation of Don Libes (libes@nist.gov). The Tcl Expect home page is http://expect.nist.gov/. Don has written an excellent in-depth tutorial of the Tcl Expect, which is _Exploring Expect_. It is the O'reilly book with the monkey on the front. Don has several references to other articles on the Expect web page.
