 The NuttShell is a very complete shell system to be used in NuttX, similar to bash and other similar options. It supports a rich set of included commands, scripting and the ability to run your own applications as "builtin" (part of the same NuttX binary). NSH is implemented as an application where most of the functionality is part of the library called `nshlib`.
 
 As such, NSH is completely optional and can be disabled so that NuttX directly starts a given task instead of the main ``nsh`` application.

 Timer Example
 --------------
 
 The previously selected example will basically consult the timer status, set a timer alarm interval, set a timer signal handler function to be notified at the alarm, which only increments a variable, and then it will start the timer. The application will periodically consult the timer status at the sample rate previously configured through the ``menuconfig`` to follow the time left until the timer expires. After the samples have been read, the application stops de timer.
