"""
|
|
This Bot uses the BotEventHandler class to handle the bot.
|
|
|
|
First, a few handler functions are defined. Then, those functions are passed to
|
|
the Broadcaster and registered at their respective places.
|
|
Then, the bot is started and the CLI-Loop is entered, where all text inputs are
|
|
inserted into the update queue for the bot to handle.
|
|
|
|
Usage:
|
|
Basic Echobot example, repeats messages. Reply to last chat from the command
|
|
line by typing "/reply <text>"
|
|
Type 'stop' on the command line to stop the bot.
