+Synopsis
+
+   xdg-file-dialog openfilename [--title TITLE] [FILENAME]
+
+   xdg-file-dialog openfilenamelist [--title TITLE] [FILENAME]
+
+   xdg-file-dialog savefilename [--title TITLE] [FILENAME]

+
+   xdg-file-dialog { --help | --manual | --version }
+
+Description
+
+   The xdg-file-dialog program can be used to let the native file selection
+   dialog handle file and directory input.
+
+   xdg-file-dialog is for use inside a desktop session only. It is not
+   recommended to use xdg-file-dialog as root.
+
+Commands
+
+   openfilename
+           Returns the filename with path for a file to read from. FILENAME
+           can optionally be used to specify path and filename of a
+           preselection.
+
+   openfilenamelist
+           Returns one or more filenames with path for files to read from,
+           each on a new line. FILENAME can optionally be used to specify
+           path and filename of a preselection.
+
+   savefilename
+           Returns the filename with path for file to write to. FILENAME can
+           optionally be used to specify path and filename of a preselection.
+
+   directory
+           Returns the path for an exsiting directory. DIRNAME can optionally
+           be used to specify a path of a preselection.
+
+Options
+
+   --title TITLE
+           Sets the dialog's title (caption) to the specified text.
+
+   --help
+           Show command synopsis.
+
+   --manual
+           Show this manualpage.
+
+   --version
+           Show the xdg-utils version information.
+
+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.
+
+Examples
+
+ xdg-file-dialog savefilename /tmp/foobar.png
+
+   Asks for a save file name starting in directory /tmp and suggesting
+   foobar.png as the filename
+
+ xdg-file-dialog directory --title "Select a target folder" /tmp
+
+   Asks for a directory name starting in directory /tmp using the text
+   "Select a target folder" as the dialog's title/caption.
