#                   : Python:
#                   :   1. Install python (v3.6 and 64 bits, this is important)
#                   : OBS:
#                   :   1. Go to Tools › Scripts
#                   :   2. Click the "Python Settings" tab
#                   :   3. Select your python install path
#                   :   4. Click the "Scripts" tab
#                   :   5. Click the "+" button and add this script
#                   :   6. Set the Timespan between Replays
#                   :   7. (optional: set Scenes on which no Replays should be saved)
#                   :   8. Check "Enable"
