middlemac version #{Middleman::Middlemac::VERSION}

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

    desc 'documentation', 'Install the sample project into your current working directory.'
    long_desc <<-HEREDOC
`documentation` will produce a sample project named `middlemac-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-docs
bundle install
bundle exec middleman server
    
    HEREDOC
    def documentation
      source = File.join('..', '..', 'documentation_project', '.')
      source = File.expand_path(source, __FILE__)
      dest = File.expand_path(File.join('.', 'middlemac-docs', '.'))
      FileUtils.cp_r(source, dest)
      puts "middlemac installed the project in\n#{dest}" 
    end


    ############################################################
    # init
    ############################################################
    desc 'init', 'Install a (mostly) blank project into your current working directory.'
    long_desc <<-HEREDOC
`init` will produce a nearly blank project named `middlemac-init/` in you
current working directory. It is a minimal, buildable project that you can
serve and test by:

cd middlemac-init
bundle install
bundle exec middleman server
    
    HEREDOC
    def init
      source = File.join('..', '..', 'fixtures', 'middlemac_app', '.')
      source = File.expand_path(source, __FILE__)
      dest = File.expand_path(File.join('.', 'middlemac-init', '.'))
      FileUtils.cp_r(source, dest)
      puts "middlemac installed the project in\n#{dest}" 
    end
