This gem adds functionality to Middleman and is not executable on its own,
other than for generating the documentation sample project. Instead, you 
must add this gem to your Middleman project's `Gemfile` and then activate 
it in your `config.rb` file.

`documentation` will produce a sample project named `middlemac-extras-docs/`
in your current working directory. This sample uses the features of this gem.
You can then serve this new project to read the documentation by:

cd middlemac-extras-docs
bundle install
bundle exec middleman server

    def documentation
      source = File.join('..', '..', 'documentation_project', '.')
      source = File.expand_path(source, __FILE__)

      FileUtils.cp_r(source, dest)
