What is Legato?

On the embedded side, Octave is built on top of Legato. The Legato Application Framework provides a set of tools and structures to build an application system for your target system. The Legato system contains all the pieces that are needed for your target system to interact with the hardware and send data over a network through Octave. Legato allows you to customize the system to only enable the hardware and software that is needed to perform the tasks you require.
