 * <h2>Chibi ?</h2>
 * I didn't want a serious name for this project. It is the Japanese word for
 * small as in small child. So ChibiOS/RT
 * @htmlonly (<span class="t_nihongo_kanji" xml:lang="ja" lang="ja">&#12385;&#12403;</span>OS/RT) @endhtmlonly
 * means small Real Time Operating System.
 * Source <a href="http://en.wikipedia.org/wiki/Chibi" target="_blank">Wikipedia</a>.
 *
 * <h2>Features</h2>
 * - Free software, GPL3 licensed. Stable releases include a exception clause
 *   to the GPL.
 * - Designed for realtime applications.
 * - Easily portable.
 * - Preemptive scheduling.
 * - 128 priority levels. Multiple threads at the same priority level allowed.
 * - Round robin scheduling for threads at the same priority level.
 * - Offers threads, virtual timers, semaphores, mutexes, condvars,
 *   event flags, messages, mailboxes, I/O queues.
 * - No static setup at compile time, there is no need to configure a maximum
 *   number of all the above objects.
 * - PC simulator target included, the development can be done on a PC
 *   under Linux or Windows.<br>
 *   Timers, I/O channels and other HW resources are simulated in a guest OS
 *   process and the application code does not need to be aware of it.
 * - No *need* for a memory allocator, all the kernel structures are static
 *   and declaratively allocated.
 * - Optional, thread safe, Heap Allocator subsystem.
 * - Optional, thread safe, Memory Pools Allocator subsystem.
 * - Blocking and non blocking I/O channels with timeout and events generation
 *   capability.
 * - Minimal system requirements: about 6KiB ROM with all options enabled and
 *   speed optimizations on. The size can shrink under 2KiB by disabling the
 *   the unused subsystems and optimizing for size.
 * - Almost totally written in C with little ASM code required for ports.
 * - Optional Hardware Abstraction Layer (HAL) with support for many device
 *   driver models and device driver implementations.
