Set a default rake task

Ever found yourself with a large Rakefile and forgot the names of frequently used tasks? Well, you can set a default Rake task so when you run rake by itself you’ll run that default task.

task :default => [:test]

task :test do
  ruby "test/unittest.rb"
end

The above is pulled from the docs. Although it’s a small thing, having a default task set (such as your test suite) can be helpful.
