+
+Description
+
+The xdg-desktop-icon program can be used to install an application launcher or
+other file on the desktop of the current user.
+
+An application launcher is represented by a *.desktop file. Desktop files are
+defined by the freedesktop.org Desktop Entry Specification. The most important
+aspects of *.desktop files are summarized below.
+
+Commands
+
+install
+    Installs FILE to the desktop of the current user. FILE can be a *.desktop
+    file or any other type of file.
+uninstall
+    Removes FILE from the desktop of the current user.
+
+Options
+
+--novendor
+
+    Normally, xdg-desktop-icon checks to ensure that a *.desktop file 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.
+
+--help
+    Show command synopsis.
+--manual
+    Show this manualpage.
+--version
+    Show the xdg-utils version information.
+
+Desktop Files
+
+An application launcher can be added to the desktop by installing 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.
+
+For a complete oveview of the *.desktop file format please visit http://
+www.freedesktop.org/wiki/Standards/desktop-entry-spec
+
+Environment Variables
+
+xdg-desktop-icon honours the following environment variables:
+
+XDG_UTILS_DEBUG_LEVEL
+    Setting this environment variable to a non-zero numerical value makes
+    xdg-desktop-icon do more verbose reporting on stderr. Setting a higher
+    value increases the verbosity.
+
+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.
+

+
+xdg-icon-resource(1)
+
+Examples
+
+The company ShinyThings Inc. has developed an application named "WebMirror" and
+would like to add a launcher for for on the desktop. The company will use
+"shinythings" as its vendor id. In order to add the application to the desktop
+there needs to be a .desktop file for the application:
+
+shinythings-webmirror.desktop:
+
+  [Desktop Entry]
+  Encoding=UTF-8
+  Type=Application
+
+  Exec=webmirror
+  Icon=shinythings-webmirror
+
+  Name=WebMirror
+  Name[nl]=WebSpiegel
+
+Now the xdg-desktop-icon tool can be used to add the webmirror.desktop file to
+the desktop:
+
+xdg-desktop-icon install ./shinythings-webmirror.desktop
+
+To add a README file to the desktop as well, the following command can be used:
+
+xdg-desktop-icon install ./shinythings-README
