First, a few callback 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:
|
|
Example of a bot-user conversation using ConversationHandler.
|
|
Send /start to initiate the conversation.
|
|
Press Ctrl-C on the command line or send a signal to the process to stop the

bot.
