+This fork follows the [upstream version](http://www.airspayce.com/mikem/arduino/AccelStepper/). Files are slightly reorganized to follow Arduino library conventions to allow for inclusion into the Arduino IDE library manager.

+
+This is the Arduino AccelStepper library. It provides an object-oriented interface for 2, 3 or 4 pin stepper motors and motor drivers.
+
+The standard Arduino IDE includes the Stepper library (http://arduino.cc/en/Reference/Stepper) for stepper motors. It is perfectly adequate for simple, single motor applications.
+
+AccelStepper significantly improves on the standard Arduino Stepper library in several ways:
+
+  - Supports acceleration and deceleration
+  - Supports multiple simultaneous steppers, with independent concurrent stepping on each stepper
+  - API functions never delay() or block
+  - Supports 2, 3 and 4 wire steppers, plus 3 and 4 wire half steppers.
+  - Supports alternate stepping functions to enable support of AFMotor (https://github.com/adafruit/Adafruit-Motor-Shield-library)
+  - Supports stepper drivers such as the Sparkfun EasyDriver (based on 3967 driver chip)
+  - Very slow speeds are supported
+  - Extensive API
+  - Subclass support
