24 * ivi-shell supports a type of shell for In-Vehicle Infotainment system.
25 * In-Vehicle Infotainment system traditionally manages surfaces with global
26 * identification. A protocol, ivi_application, supports such a feature
27 * by implementing a request, ivi_application::surface_creation defined in
28 * ivi_application.xml.
30 * The ivi-shell explicitly loads a module to add business logic like how to
31 * layout surfaces by using internal ivi-layout APIs.
