A python script to automatically reply to new skype messages.
main.py --username <your_skype_username> --password <your_skype_password> --response response.txt --timeout 60
This will reply to new messages with the contents of the file response.txt if the sender's last message was at least 60 seconds ago.
The script uses the SkPy package to interact with the Skype API. Because the API is undocumented and might change at any time the code could break unpredictably as well.
