* This is implementation of Autostart Spec

* The Autostart Directories are $XDG_CONFIG_DIRS/autostart.
* If the same filename is located under multiple Autostart Directories only the file under
* the most important directory should be used.
*
* Example: If $XDG_CONFIG_HOME is not set the Autostart Directory in the user's home directory
* is ~/.config/autostart/
* Example: If $XDG_CONFIG_DIRS is not set the system wide Autostart Directory is /etc/xdg/autostart/
* Example: If $XDG_CONFIG_HOME and $XDG_CONFIG_DIRS are not set and the two files
* /etc/xdg/autostart/foo.desktop and ~/.config/autostart/foo.desktop exist then only the file
* ~/.config/autostart/foo.desktop will be used because ~/.config/autostart/ is more important
* than /etc/xdg/autostart/.
*
* If Hidden key is set true in .desktop file, file MUST be ignored.
* OnlyShowIn and NotShowIn (list of strings identifying desktop environments) if (or if not)
* contains environment name, MUST not be started/not started.
* TryExec is same as for .desktop spec.
