     6Don't forget to enable inline mode with @BotFather
     7
     8First, a few handler functions are defined. Then, those functions are passed to
     9the Application and registered at their respective places.
    10Then, the bot is started and runs until we press Ctrl-C on the command line.
    11
    12Usage:
    13Basic inline bot example. Applies different text transformations.
    14Press Ctrl-C on the command line or send a signal to the process to stop the
    15bot.
