Haiku API reference is still incomplete.

The system is made of several kits, handling a particular part of the work. Each of them needs an introduction text, explaining what it does and providing some hints on how to use it.

Go to http://api.haiku-os.org and find a kit that's missing here. Write some introduction text about this kit to explain what it does. Look at the existing documentation to get an idea of what's to be done.
