Over the past few months, Samsung's latest payment to Enlightenment developers has been for constructing documentation. There's few open-source projects that actually have very good documentation, since writing docs are among the least entertaining tasks for code developers, but Samsung has paid the Enlightenment developers to write up some nice documentation for their code.
Samsung paid for the work while the ProFUSION mobile development company worked on the documentation. Details on the documentation can be found here. There's now documentation (or better documentation) coverage for Eina, Eet, Evas, Ecore, Edje, Emotion, and Elementary components.
Samsung's primary area where they employ Enlightenment's capabilities is on their Linux-based Bada operating system. Bada is used for various Samsung mobile phones from low-end to high-end devices, but is certainly not as well known as Google's Android, Microsoft Windows Phone 7, MeeGo, Apple iOS, or even Palm/HP webOS. With Samsung continuing to sponsor Enlightenment development, they must still have some hope for their mobile operating system in this very competitive space.
