          bash
        
bundle gem lorem
gem build lorem.gemspec
gem push lorem-0.0.1.gem
bundle
rake -T
rake build
rake install
rake release

          lorem.gemspec
        
# -*- encoding: utf-8 -*-
$:.push File.expand_path("../lib", __FILE__)
require "lorem/version"

Gem::Specification.new do |s|
  s.name        = "lorem"
  s.version     = Lorem::VERSION
  s.platform    = Gem::Platform::RUBY
  s.authors     = ["Ryan Bates"]
  s.email       = ["ryan@railscasts.com"]
  s.homepage    = ""
  s.summary     = %q{Lorem ipsum generator}
  s.description = %q{Simply generates lorem ipsum text.}
  
  s.add_development_dependency "rspec"

  s.rubyforge_project = "lorem"

  s.files         = `git ls-files`.split("\n")
  s.test_files    = `git ls-files -- {test,spec,features}/*`.split("\n")
  s.executables   = `git ls-files -- bin/*`.split("\n").map{ |f| File.basename(f) }
  s.require_paths = ["lib"]
end

          Gemfile
        
source "http://rubygems.org"

          Specify your gem's dependencies in lorem.gemspec
        
gemspec

          Rakefile
        
require 'bundler'
Bundler::GemHelper.install_tasks

          lib/lorem.rb
