Summary	C library and tools for interacting with the linux GPIO character device
Description	Since linux 4.8 the GPIO sysfs interface is deprecated. User space should use the character device instead. This library encapsulates the ioctl calls and data structures behind a straightforward API. Unfortunately interacting with the linux device file can no longer be done using only standard command-line tools. This is the reason for creating a library encapsulating the cumbersome, ioctl-based kernel-userspace interaction in a set of convenient functions and opaque data structures. Additionally this project contains a set of command-line tools that should allow an easy conversion of user scripts to using the character device.
