+'''Pexpect is a Python module for spawning child applications and controlling
+them automatically. 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. Other Expect-like modules for Python
+require TCL and Expect or require C extensions to be compiled. Pexpect does not
+use C, Expect, or TCL extensions. It should work on any platform that supports
+the standard Python pty module. The Pexpect interface focuses on ease of use so
+that simple tasks are easy.
+
+There are two main interfaces to the Pexpect system; these are the function,
+run() and the class, spawn. The spawn class is more powerful. The run()
+function is simpler than spawn, and is good for quickly calling program. When
+you call the run() function it executes a given program and then returns the
+output. This is a handy replacement for os.system().
+
+For example::
+
+    pexpect.run('ls -la')
+
+The spawn class is the more powerful interface to the Pexpect system. You can
+use this to spawn a child program then interact with it by sending input and
+expecting responses (waiting for patterns in the child's output).
+
+For example::
+
+    child = pexpect.spawn('scp foo user@example.com:.')
+    child.expect('Password:')
+    child.sendline(mypassword)
+
+This works even for commands that ask for passwords or other input outside of
+the normal stdio streams. For example, ssh reads input directly from the TTY
+device which bypasses stdin.
