Usage: rpub generate [-slach]

Generate one or more standard files to get started with a new project.  By
default an entire skeleton project is generated, but by passing the -s, -l, -c
options you can generate just a single file.

Options:
EOS
          opts.separator ' '

          opts.on '-s', '--[no-]styles', 'Generate default stylesheet' do |v|
            @all = false if v
            @styles = v
          end

          opts.on '-l', '--[no-]layout', 'Generate default HTML layout' do |v|
            @all = false if v
            @layout = v
          end

          opts.on '-c', '--[no-]config', 'Generate default configuration' do |v|
            @all = false if v
            @config = v
          end
