# : is selector for response, . selectors make it cascaded and random response is selected
# ? is selector for pattern
# $ is used for setting response and template variables

# > is used to direct the response to previous or some other pattern

//a botlang code, you can also run the code directly from file
//Now we will load the object so that it can be executed
$bot->load($botcode);
//or you can run a BotLang script directly
$bot->load("script://intro.botlang"); // script prefix is important for it to know that you are loading script

//EXECUTION

//Now that your bot is prepared with default behaviour you can run it on different templates
