+               attributes, such as active state, bias, drive, edge detection
+               and debounce period
 
 * gpioget    - read values of specified GPIO lines
 
-* gpioset    - set values of specified GPIO lines, potentially keep the lines
-               exported and wait until timeout, user input or signal
+* gpioset    - set values of specified GPIO lines, holding the lines until the

-* gpiofind   - find the gpiochip name and line offset given the line name
