In Rails, the Rakefile allows you to run tasks using the application's environment. There are plenty of other non-rails things that rake is useful for. Its not something Rails specific and you can use any Ruby code in it. Rails and many gems use rake for things like migrations, cron jobs, and any other task that needs to run outside the application server.
