+The Qt GUI can either use the standard system style/themes or custom stylesheets.
+The available standard styles that are installed on the system will be listed when running the executable command line help.
+To use a provided system style, use the --style command line argument.
+To use a custom Qt stylesheet file, set an environment variable named FCEUX_QT_STYLESHEET that contains
+the full path to the file. This will check for this at startup.
+If the variable is defined and the file is readable by the program,
+then the styling settings will be used by the GUI.

Bash Shell Setup Example:

+ export FCEUX_QT_STYLESHEET=/home/me/myFceux.qss ++ For information on Qt stylesheet syntax, see Qt online documentation
