The Specification class contains the metadata for a Gem. Typically defined in a .gemspec file or a Rakefile, and looks like this:

spec = Gem::Specification.new do |s|
  s.name = 'example'
  s.version = '1.0'
  s.summary = 'Example gem specification'
  ...
end

For a great way to package gems, use Hoe.
