The build command allows you to create a gem from a ruby gemspec.

The best way to build a gem is to use a Rakefile and the Gem::PackageTask
which ships with RubyGems.

The gemspec can either be created by hand or extracted from an existing gem
with gem spec:

  $ gem unpack my_gem-1.0.gem
  Unpacked gem: '.../my_gem-1.0'
  $ gem spec my_gem-1.0.gem --ruby > my_gem-1.0/my_gem-1.0.gemspec
  $ cd my_gem-1.0
  [edit gem contents]
  $ gem build my_gem-1.0.gemspec

Gems can be saved to a specified filename with the output option:

  $ gem build my_gem-1.0.gemspec --output=release.gem

    EOF
  end

  def usage # :nodoc:
    "#{program_name} GEMSPEC_FILE"
  end

  def execute
    gemspec = get_one_gem_name

    unless File.exist? gemspec
      gemspec += '.gemspec' if File.exist? gemspec + '.gemspec'
    end

    if File.exist? gemspec
      Dir.chdir(File.dirname(gemspec)) do
        spec = Gem::Specification.load File.basename(gemspec)

        if spec
          Gem::Package.build(
            spec,
            options[:force],
            options[:strict],
            options[:output]
          )
        else
          alert_error "Error loading gemspec. Aborting."
          terminate_interaction 1
        end
      end
    else
      alert_error "Gemspec file not found: #{gemspec}"
      terminate_interaction 1
    end
  end
