/**
* @mainpage Introdution
* @author Giovanni Di Sirio (gdisirio@users.sourceforge.net).
*
* <h2>Why Nil?</h2>
* Of course because it is so small that it is almost nil.
* I wrote Nil because I wanted to experiment with an idea I had
* regarding a minimal RTOS. Basically I wanted to verify how small
* could be an RTOS while retaining useful features.
*
* <h2>Features</h2>
* - Free software, GPL3 licensed. Stable releases include a exception clause
* to the GPL.
* - Designed for realtime applications.
* - Easily portable.
* - Preemptive scheduling.
* - Each thread has its own priority level.
* - Offers tasks, time, semaphores, event flags, timeouts.
* - Fully static.
* - Minimal system requirements: about 700 bytes ROM with all options enabled.
* - Almost totally written in C with little ASM code required for ports.
* - Compatible with ChibiOS/HAL.
* - API compatible with ChibiOS/RT of which, ChibiOS/NIL, is functionally
* a subset.
