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.
