Extending the package task

[Magnus Melander]

Hi!
I have successfully extended the build task as suggested in the documentation:

build do
   puts("Do extra stuff")
end

However, when I try to do the same with the package task, it does not work:

package do
   puts("Custom packaging")  # never happens
end

I can't see any reason why it should not work, but maybe my understanding of 
buildr is incorrect.
I'm running version 1.47 of buildr.

Regards,
Magnus
