Send Twitter search results to a Zulip stream.

Depends on: twitter-python version 1.0 or later

To use this script:

1. Set up Twitter authentication, as described below
2. Subscribe to the stream that will receive Twitter updates (default stream: twitter)
3. Test the script by running it manually, like this:

/usr/local/share/zulip/integrations/twitter/twitter-search-bot --search="@nprnews,quantum physics"

4. Configure a crontab entry for this script. A sample crontab entry
that will process tweets every 5 minutes is:

*/5 * * * * /usr/local/share/zulip/integrations/twitter/twitter-search-bot --search="@nprnews,quantum physics"

== Setting up Twitter authentications ==

Run this on a personal or trusted machine, because your API key is
visible to local users through the command line or config file.

This bot uses OAuth to authenticate with Twitter. Please create a
~/.zulip_twitterrc with the following contents:

[twitter]
consumer_key =
consumer_secret =
access_token_key =
access_token_secret =

In order to obtain a consumer key & secret, you must register a
new application under your Twitter account:

1. Go to http://dev.twitter.com
2. Log in
3. In the menu under your username, click My Applications
4. Create a new application

Make sure to go the application you created and click "create my
access token" as well. Fill in the values displayed.
