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/wiki/Specifications/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 precedes 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 necessary 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.

       --help
	   Show command synopsis.

       --manual
	   Show this manual page.

       --version
	   Show the xdg-utils version information.

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 necessary 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#category-registry

       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/Specifications/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 relevant 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 necessary 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
