Subsystems

Mostly a subsystem is a part offering a specific functionality with a defined interface and can have multiple different implementations. (See sw/airborne/subsystems/...)

They are selected and configured with a <subsystem name="foo" type="bar"> in the firmware section of the airframe file.

All this does is basically include a makefile foo_bar.makefile that adds the respective sources and adds a few configuration options. (See conf/autopilot/subsystems/...)

This makes it easier to put an airframe file together (they replace the old raw makefile section) and also allows us to change the code and move/rename files behind the scenes without breaking everyones airframe files.

See FirmwareArchitecture for the differences to Modules.
