  10 ## Introduction
  11
  12 The `meta-agl-demo` layer is the reference user interface layer for the DEMO
  13 platform of Automotive Grade Linux (AGL).
  14 The layer provides a reference platform and applications.
  15 The BitBake target name for the DEMO platform is `agl-demo-platform`, which is
  16 the full DEMO platform image.

 126 ## Packagegroups
 127
 128 AGL DEMO Platform's
 129 [packagegroups](https://www.yoctoproject.org/docs/2.4.4/dev-manual/dev-manual.html#usingpoky-extend-customimage-customtasks)
 130 consist of the following:
 131
 132 ### packagegroup-agl-demo-platform
 133
 134 This packagegroup is used for generating the `agl-demo-platform` image,
 135 which is the full image for the AGL distributions IVI profile.
 136 You can see the recipe (i.e. `agl-demo-platform.bb`) that installs
 137 the `packagegroup-agl-demo-platform` packagegroup
 138 [here](https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-platform/images/agl-demo-platform.bb).
 139
 140 As meta-agl's design of packagegroups, the `agl-demo-platform.bb` recipe installs
 141 only `packagegroup-agl-demo-platform` and the packages of the DEMO applications.
 142
 143 ``agl-demo-platform`` contains the following three packagegroups:
 144
 145   * `packagegroup-agl-image-minimal`
 146   * `packagegroup-agl-image-ivi`
 147   * `packagegroup-agl-demo-platform`
 148
 149 ### packagegroup-agl-appfw*
 150
 151 These packagegroups contain packages for the AGL distribution's
 152 Application Framework.
 153 Subsystem should maintain `packagegroup-agl-appfw-[subsystem].bb`, which
 154 should hold sufficient packages for the Application Framework.
 155
 156 Subsystems also can maintain their own packagegroups using appropriate
 157 `recipes-*/`.
 158 For example, Qt5 has two packagegroups in `meta-agl-demo`:
 159 `packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`,
 160 which are under `recipes-qt/`.
 161
 162 The `packagegroup-agl-appfw-native-qt5` is included by
 163 `packagegroup-agl-appfw-native` because Qt5 belongs to native application
 164 framework of AGL Distro.
 165
 166 Because the `packagegroup-agl-demo-qt-examples` is not mandatory for
 167 the AGL Application Framework and the AGL DEMO, the packagegroup is added
 168 to the layer's `local.conf` file only when needed.
