They're implemented using [slixmpp](https://slixmpp.readthedocs.io/).
These bots are written using [slixmpp](https://slixmpp.readthedocs.io/) or [xbotlib](https://git.vvvvvvaria.org/decentral1se/xbotlib).
The idea is that you create a single python file (`mybot.py` for example) and using the `slixmpp` library, you write a single Python class which knows how to speak XMPP, join rooms, respond to commands etc (see [ClientXMPP](https://slixmpp.readthedocs.io/api/clientxmpp.html#slixmpp.clientxmpp.ClientXMPP) for more). Following the logbot/streambot example, you can create a command line interface using `argparse` and then start to run it on your own computer first for testing and fun (and not spamming everyone else until your bot is ready!).
