what is (.:format) appended to url path during rake routes?

When I run rake routes, I get something like this:

signin        /signin(.:format)                            application#signin

What is the (.:format) in the middle?

It's an optional format. It matches URLs like:

/signin
/signin.html
/signin.json

This format can then be used in the controller. For example:

class UsersController < ApplicationController
  def index
    @users = User.all
    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render xml: @users}
      format.json { render json: @users}
    end
  end
end

This code snippet is from Action Controller Overview. See more details in the routing guide.
