+GPIO Library
+============
+
+Overview
+--------
+
+The XMOS GPIO library allows you to access xCORE ports as low-speed GPIO.
+
+Although xCORE ports can be directly accessed via the xC programming
+language this library allows more flexible usage. In particular, it
+allows splitting a multi-pin output/input port to be able to use
+the individual pins independently. It also allows accessing ports
+across separate XMOS tiles or separate XMOS chips.
+
+Features
+........
+
+ * Abstract interface to GPIO functionality of XMOS ports
+ * Allow control of individual bits of multi-bit ports
+ * Allow access to ports across tiles
+
+Operating modes
+...............
+
+ * Multi-bit output for individual access to the pins of a multi-bit output port
+ * Multi-bit input for individual access to the pins of a multi-bit input port
+ * Multi-bit input for individual access to the pins of a multi-bit
+   input port allowing the application to react to events on those pins
+
+Software version and dependencies
+.................................
+
+The CHANGELOG contains information about the current and previous versions.
+For a list of direct dependencies, look for DEPENDENT_MODULES in lib_gpio/module_build_info.
