This installer will guide you through the tog integration process. The installer
downloads a few plugins over the internet so the time it takes depends in a great
measure of your bandwidth, but usually it should take a few minutes.

Here's what you can expect from the installation process:

 1. All the tog's dependencies will be installed for you.
 2. The installer will generate a few migrations required by the dependencies
 4. The host app will be a working tog instance after the installation.

Don't worry if anything goes wrong. This installer will advise you on how to
solve any problems.

Press Enter to continue, or Ctrl-C to abort.}

Tog includes its own user authentication library: tog_user. It's based
on the great restful-authentication plugin and well suited to work out-the-box.

If you're creating a new app #{"it's definitely recommended to install this plugin".green.bold}.
If you've already using a user library in the host app you can skip this step.

Press Enter to install tog_user, or 'n' to skip this step

Hurrah!... everything should be fine now. Some things you could try:

* Run the tests. Just run: '#{"rake db:test:prepare && rake tog:plugins:test".green.bold}'.
* Start the app in your favorite server and check your new, shiny tog installation.  
* Visit http://wiki.github.com/tog/tog if you need technical read about the platform.
* You can install more tog plugins. For a list of available plugins check 
  http://www.toghq.com/tog_plugins
