print("""Logitech G203 Prodigy / Lightsync Mouse LED control
Usage:
\tg203-led [lightsync] solid {color} - Solid color mode
\tg203-led [lightsync] cycle [{rate} [{brightness}]] - Cycle through all colors
\tg203-led [lightsync] breathe {color} [{rate} [{brightness}]] - Single color breathing
\tg203-led [lightsync] intro {on|off} - Enable/disable startup effect
\tg203-led [lightsync] dpi {dpi} - Set mouse dpi
Arguments:
\tColor: RRGGBB (RGB hex value)
\tRate: 1000-60000 (Number of milliseconds. Default: 10000ms)
\tBrightness: 1-100 (Percentage. Default: 100%)
\tDPI: 200-8000 (Prodigy), 50-8000 (Lightsync)
Assumes Prodigy by default unless "lightsync" is given as the first command argument.
This ensures backward compatibility.
Lightsync additional features:
\tg203-led lightsync triple {color color color} - Sets all 3 colors from left to right.
\tg203-led lightsync wave {rate} [{brightness} [{direction}]] - Like cycle but appears to move right or left.
\tg203-led lightsync blend [{rate} [{brightness}]] - Like breathe with the side colors changing after some delay.
\tDirection is either "left" or "right". Default: right).
Note that the lightsync setting will not persist.
There is onboard memory for persistence but it is not used by this script.""")
