Welcome to pylibftdi's documentation!
+pylibftdi is a simple library interacting with FTDI devices to provide
+serial and parallel IO from Python.
+The two main use cases it serves are:
+* the need to control or monitor external equipment, for which a FTDI
+ module may be a cheap and reliable starting point.
+* the need to interact with existing devices which are known to contain
+ FTDI chipsets for their USB interface.
+FTDI (http://www.ftdichip.com) create devices (chipsets, modules,
+cables etc) to interface devices to the USB port of your computer.
+libftdi (http://www.intra2net.com/en/developer/libftdi/) is an open source
+driver to communicate with these devices, and runs on top of libusb.
+It works on Windows, Linux, and Mac OS X, and likely other systems too.
+pylibftdi is a pure Python module which interfaces (via ctypes) to libftdi,
+exposing a simple file-like API to connected devices. It supports serial and
+parallel IO in a straight-forward way, and aims to be one of the simplest
+ways of interacting with the world outside your PC.
