+Pexpect is a Pure Python Expect-like module
+
+Pexpect makes Python a better tool for controlling other applications.
+
+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.
+
+If you want to work with the development version of the source code then please
+read the DEVELOPERS document in the root of the source code tree.
