compton-trans is a bash script that sets _NET_WM_WINDOW_OPACITY attribute of a window using standard X11
       command-line utilities, including xprop(1) and xwininfo(1). It is similar to transset(1) or
       transset-df(1).

       •   Set the opacity of the window with specific window ID to 75%:

               compton-trans -w "$WINDOWID" 75

       •   Set the opacity of the window with the name "urxvt" to 75%:

               compton-trans -n "urxvt" 75

       •   Set current window to opacity of 75%:

               compton-trans -c 75

       •   Select target window and set opacity to 75%:

               compton-trans -s 75

       •   Increment opacity of current active window by 5%:

               compton-trans -c +5

       •   Decrement opacity of current active window by 5%:

               compton-trans -c -- -5

-wWINDOW_ID
           Specify the window id of the target window.

       -nWINDOW_NAME
           Specify and try to match a window name.

       -c
           Specify the currently active window as target. Only works if EWMH _NET_ACTIVE_WINDOW property exists
           on root window.

       -s
           Select target window with mouse cursor. This is the default if no window has been specified.

       -oOPACITY
           Specify the new opacity value for the window. This value can be anywhere from 1-100. If it is
           prefixed with a plus or minus (+/-), this will increment or decrement from the target window’s
           current opacity instead.
