/**
* @mainpage Introduction
* @author Giovanni Di Sirio (gdisirio@users.sourceforge.net).
*
* <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, binary and counter semaphores, mutexes,
* condvars, event sources, event flags, messages, mailboxes.
* - 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.
* - 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.
* - Compatible with ChibiOS/HAL.
