/**
 * SECTION:gs-app
 * @title: GsApp
 * @include: gnome-software.h
 * @stability: Unstable
 * @short_description: An application that is either installed or that can be installed
 *
 * This object represents a 1:1 mapping to a .desktop file. The design is such
 * so you can't have different GsApp's for different versions or architectures
 * of a package. This rule really only applies to GsApps of kind %AS_APP_KIND_DESKTOP
 * and %AS_APP_KIND_GENERIC. We allow GsApps of kind %AS_APP_KIND_OS_UPDATE or
 * %AS_APP_KIND_GENERIC, which don't correspond to desktop files, but instead
 * represent a system update and its individual components.
 *
 * The #GsPluginLoader de-duplicates the GsApp instances that are produced by
 * plugins to ensure that there is a single instance of GsApp for each id, making
 * the id the primary key for this object. This ensures that actions triggered on
 * a #GsApp in different parts of gnome-software can be observed by connecting to
 * signals on the #GsApp.
 *
 * Information about other #GsApp objects can be stored in this object, for
 * instance in the gs_app_add_related() method or gs_app_get_history().
