[Qbs] A simple project that copy an executable does not work

[Vincent Hui]

Hi Richard,

Thank you very much for your reply.

I am creating toy projects for learning how to use qbs.

In the document of Rule, A simple example is not a complete example. It
does not tell user to assign the product type to "txt_output" explicitly.

I hope the document can be improved in the future.

Thank you again,
Vincent
