[typo] [TYPO] config object is ... what?

[Dan Bikle]

People,

I'm new to Rails so I'm looking at other people's source code.

I'm poking around in the Rails code for the blog engine named 'typo':
http://typo.leetsoft.com/

I'm looking at this file:
http://typo.leetsoft.com/trac/file/trunk/app/controllers/application.rb

I see:

  before_filter :reload_settings

which is calling this:

  def reload_settings
    config.reload
  end

I'm curious about the object named 'config'.

I'm trying to figure out if it is a Rails object or Typo object.

The fact that it has a reload() method suggests to me that is an object
built from an ActiveRecord class.

I tried poking around with grep and got too many lines back since config
is such a common token.

What is the config object?

Anyone know?
