I do not know it for DR17, but in DR16 you have to extract your user
themes in ~/.enlightenment/themes/ (every theme in a seperate dir) and
then you can change the theme with a middle-mouse click and select one
theme from the Themes submenu (you maybe have to restart enlightenment
after u installed a theme, to accomplish this u also do a middle-click
and click on restart enlightenment or something like that).
