+Pexpect is a pure Python module for spawning child applications; controlling
+them; and responding to expected patterns in their output. Pexpect works like
+Don Libes' Expect. Pexpect allows your script to spawn a child application and
+control it as if a human were typing commands.
+
+Pexpect can be used for automating interactive applications such as ssh, ftp,
+passwd, telnet, etc. It can be used to a automate setup scripts for duplicating
+software package installations on different servers. It can be used for
+automated software testing. Pexpect is in the spirit of Don Libes' Expect, but
+Pexpect is pure Python. Unlike other Expect-like modules for Python, Pexpect
+does not require TCL or Expect nor does it require C extensions to be compiled.
+It should work on any platform that supports the standard Python pty module.
+The Pexpect interface was designed to be easy to use.
