DESCRIPTION
       The xdg-desktop-menu program can be used to install new menu entries to the desktop's application menu.

       The application menu works according to the XDG Desktop Menu Specification at
       http://www.freedesktop.org/Standards/menu-spec

COMMANDS
       install
              Install one or more applications in a submenu of the desktop menu system.

              desktop-file: A desktop file represents a single menu entry in the menu. Desktop files are defined by
              the freedesktop.org Desktop Entry Specification. The most important aspects of *.desktop files are
              summarized below.

              Menu entries can be added to the menu system in two different ways. They can either be added to a
              predefined submenu in the menu system based on one or more category keywords, or they can be added to a
              new submenu.

              To add a menu entry to a predefined submenu the desktop file that represents the menu entry must have a
              Categories= entry that lists one or more keywords. The menu item will be included in an appropriate
              submenu based on the included keywords.

              To add menu items to a new submenu the desktop-files must be preceded by a directory-file that describes
              the submenu. If multiple desktop-files are specified, all entries will be added to the same menu. If
              entries are installed to a menu that has been created with a previous call to xdg-desktop-menu the
              entries will be installed in addition to any already existing entries.

              directory-file: The *.directory file indicated by directory-file represents a submenu. The directory
              file provides the name and icon for a submenu. The name of the directory file is used to identify the
              submenu.

              If multiple directory files are provided each file will represent a submenu within the menu that
              preceeds it, creating a nested menu hierarchy (sub-sub-menus). The menu entries themselves will be added
              to the last submenu.

              Directory files follow the syntax defined by the freedesktop.org Desktop Entry Specification.

       uninstall
              Remove applications or submenus from the desktop menu system previously installed with xdg-desktop-menu
              install.

              A submenu and the associated directory file is only removed when the submenu no longer contains any menu
              entries.

       forceupdate
              Force an update of the menu system.

              This command is only useful if the last call to xdg-desktop-menu included the --noupdate option.

OPTIONS
       --noupdate
              Postpone updating the menu system. If multiple updates to the menu system are made in sequence this flag
              can be used to indicate that additional changes will follow and that it is not necassery to update the
              menu system right away.

       --novendor
              Normally, xdg-desktop-menu checks to ensure that any *.directory and *.desktop files to be installed has
              a vendor prefix. This option can be used to disable that check.

              A vendor prefix consists of alpha characters ([a-zA-Z]) and is terminated with a dash ("-"). Companies
              and organizations are encouraged to use a word or phrase, preferably the organizations name, for which
              they hold a trademark as their vendor prefix. The purpose of the vendor prefix is to prevent name
              conflicts.

       --mode mode
              mode can be user or system. In user mode the file is (un)installed for the current user only. In system
              mode the file is (un)installed for all users on the system. Usually only root is allowed to install in
              system mode.

              The default is to use system mode when called by root and to use user mode when called by a non-root
              user.

DESKTOP FILES
       An application item in the application menu is represented by a *.desktop file. A *.desktop file consists of a
       [Desktop Entry] header followed by several Key=Value lines.

       A *.desktop file can provide a name and description for an application in several different languages. This is
       done by adding a language code as used by LC_MESSAGES in square brackets behind the Key. This way one can
       specify different values for the same Key depending on the currently selected language.

       The following keys are often used:

       Value=1.0
              This is a mandatory field to indicate that the *.desktop file follows the 1.0 version of the
              specification.

       Type=Application
              This is a mandatory field that indicates that the *.desktop file describes an application launcher.

       Name=Application Name
              The name of the application. For example Mozilla

       GenericName=Generic Name
              A generic description of the application. For example Web Browser

       Comment=Comment
              Optional field to specify a tooltip for the application. For example Visit websites on the Internet

       Icon=Icon File
              The icon to use for the application. This can either be an absolute path to an image file or an
              icon-name. If an icon-name is provided an image lookup by name is done in the user's current icon theme.
              The xdg-icon-resource command can be used to install image files into icon themes. The advantage of
              using an icon-name instead of an absolute path is that with an icon-name the application icon can be
              provided in several different sizes as well as in several differently themed styles.

       Exec=Command Line
              The command line to start the application. If the application can open files the %f placeholder should
              be specified. When a file is dropped on the application launcher the %f is replaced with the file path
              of the dropped file. If multiple files can be specified on the command line the %F placeholder should be
              used instead of %f. If the application is able to open URLs in addition to local files then %u or %U can
              be used instead of %f or %F.

       Categories=Categories
              A list of categories separated by semi-colons. A category is a keyword that describes and classifies the
              application. By default applications are organized in the application menu based on category. When menu
              entries are explicitly assigned to a new submenu it is not necassery to list any categories.

              When using categories it is recommended to include one of the following categories: AudioVideo,
              Development, Education, Game, Graphics, Network, Office, Settings, System, Utility.

              See Appendix A of the XDG Desktop Menu Specification for information about additional categories.
              http://standards.freedesktop.org/menu-spec/menu-spec-1.0.html

       MimeType=Mimetypes
              A list of mimetypes separated by semi-colons. This field is used to indicate which file types the
              application is able to open.

       http://www.freedesktop.org/wiki/Standards/desktop-entry-spec

DIRECTORY FILES
       The appearance of submenu in the application menu is provided by a *.directory file. In particular it provides
       the title of the submenu and a possible icon. A *.directory file consists of a [Desktop Entry] header followed
       by several Key=Value lines.

       A *.directory file can provide a title (name) for the submenu in several different languages. This is done by
       adding a language code as used by LC_MESSAGES in square brackets behind the Key. This way one can specify
       different values for the same Key depending on the currently selected language.

       The following keys are relevqnt for submenus:

       Value=1.0
              This is a mandatory field to indicate that the *.directory file follows the 1.0 version of the Desktop
              Entry specification.

       Type=Directory
              This is a mandatory field that indicates that the *.directory file describes a submenu.

       Name=Menu Name
              The title of submenu. For example Mozilla

       Comment=Comment
              Optional field to specify a tooltip for the submenu.

       Icon=Icon File
              The icon to use for the submenu. This can either be an absolute path to an image file or an icon-name.
              If an icon-name is provided an image lookup by name is done in the user's current icon theme. The
              xdg-icon-resource command can be used to install image files into icon themes. The advantage of using an
              icon-name instead of an absolute path is that with an icon-name the submenu icon can be provided in
              several different sizes as well as in several differently themed styles.

ENVIRONMENT VARIABLES
       xdg-desktop-menu honours the following environment variables:

       XDG_UTILS_DEBUG_LEVEL
              Setting this environment variable to a non-zero numerical value makes xdg-desktop-menu do more verbose
              reporting on stderr. Setting a higher value increases the verbosity.

       XDG_UTILS_INSTALL_MODE
              This environment variable can be used by the user or administrator to override the installation mode.
              Valid values are user and system.

EXIT CODES
       An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes
       can be returned:

       1      Error in command line syntax.

       2      One of the files passed on the command line did not exist.

       3      A required tool could not be found.

       4      The action failed.

       5      No permission to read one of the files passed on the command line.

EXAMPLES
       The company ShinyThings Inc. has developed an application named "WebMirror" and would like to add it to the
       application menu. The company will use "shinythings" as its vendor id. In order to add the application to the
       menu there needs to be a .desktop file with a suitable Categories entry:

       shinythings-webmirror.desktop:

         [Desktop Entry]
         Encoding=UTF-8
         Type=Application

         Exec=webmirror
         Icon=webmirror

         Name=WebMirror
         Name[nl]=WebSpiegel

         Categories=Network;WebDevelopment;


       Now the xdg-desktop-menu tool can be used to add the shinythings-webmirror.desktop file to the desktop
       application menu:

       xdg-desktop-menu install ./shinythings-webmirror.desktop


       Note that for the purpose of this example the menu items are available in two languages, English and Dutch. The
       language code for Dutch is nl.

       In the next example the company ShinyThings Inc. will add its own submenu to the desktop application menu
       consisting of a "WebMirror" menu item and a "WebMirror Admin Tool" menu item.

       First the company needs to create two .desktop files that describe the two menu items. Since the items are to
       be added to a new submenu it is not necassery to include a Categories= line:

       shinythings-webmirror.desktop:

         [Desktop Entry]
         Encoding=UTF-8
         Type=Application

         Exec=webmirror
         Icon=shinythings-webmirror

         Name=WebMirror
         Name[nl]=WebSpiegel


       shinythings-webmirror-admin.desktop:

         [Desktop Entry]
         Encoding=UTF-8
         Type=Application

         Exec=webmirror-admintool
         Icon=shinythings-webmirror-admintool

         Name=WebMirror Admin Tool
         Name[nl]=WebSpiegel Administratie Tool


       In addition a .directory file needs to be created to provide a title and icon for the sub-menu itself:

       shinythings-webmirror.directory:

         [Desktop Entry]
         Encoding=UTF-8

         Icon=shinythings-webmirror-menu

         Name=WebMirror
         Name[nl]=WebSpiegel


       These file can now be installed with:

       xdg-desktop-menu install ./shinythings-webmirror.directory \
             ./shinythings-webmirror.desktop ./shinythings-webmirror-admin.desktop


       The menu entries could also be installed one by one:

       xdg-desktop-menu install --noupdate ./shinythings-webmirror.directory \
             ./shinythings-webmirror.desktop
       xdg-desktop-menu install --noupdate ./shinythings-webmirror.directory \
             ./shinythings-webmirror-admin.desktop
       xdg-desktop-menu forceupdate


       Although the result is the same it is slightly more efficient to install all files at the same time.

       The *.desktop and *.directory files reference icons with the names webmirror, webmirror-admin and
       webmirror-menu which should also be installed. In this example the icons are installed in two different sizes,
       once with a size of 22x22 pixels and once with a size of 64x64 pixels:

       xdg-icon-resource install --size 22 ./wmicon-22.png shinythings-webmirror
       xdg-icon-resource install --size 22 ./wmicon-menu-22.png shinythings-webmirror-menu
       xdg-icon-resource install --size 22 ./wmicon-admin-22.png shinythings-webmirror-admin
       xdg-icon-resource install --size 64 ./wmicon-64.png shinythings-webmirror
       xdg-icon-resource install --size 64 ./wmicon-menu-64.png shinythings-webmirror-menu
       xdg-icon-resource install --size 64 ./wmicon-admin-64.png shinythings-webmirror-admin
