Simple Bot to reply to Telegram messages.
First, a few handler functions are defined. Then, those functions are passed to
the Application and registered at their respective places.
Then, the bot is started and runs until we press Ctrl-C on the command line.
Usage:
Basic Echobot example, repeats messages.
Press Ctrl-C on the command line or send a signal to the process to stop the
bot.
