CI Application with multiple roots

[eluser]yacman[/eluser]
You can use CI's Routes to route requests to your controllers however you want.

or you could have:
/controllers/news.php
/controllers/politics.php
/controllers/sports.php
/controllers/weather.php

/models/news_model.php
/models/politics_model.php
/models/sports_model.php
/models/weather_model.php

Or you could have a single controller:

/controllers/home.php
with functions, news, politics, sports, weather.
