"""Simple Bot to reply to Telegram messages.
This program is dedicated to the public domain under the CC0 license.
This Bot uses the Updater class to handle the bot.
First, a few handler functions are defined. Then, those functions are passed to
the Dispatcher and registered at their respective places.
Then, the bot is started and runs until we press Ctrl-C on the command line.
Usage:
Basic inline bot example. Applies different text transformations.
Press Ctrl-C on the command line or send a signal to the process to stop the
bot.
