Haha I mean when you have a rake task called `build`, you invoke it with `bundle exec rake build`, so this will when you run `bundle exec rake build`, this task will just run `bundle exec rake build` until you run out of memory :P

Keep the three lines you added above and add a new task called `manpage` or `man` to the list of dependencies:

```ruby
task :build => [:gemspec, :man] do
  # build the gem ...
end
```
