This means that you expect that the files have been copied here first, but
you're not guaranteeing that.

[ricow1, 2013/02/19 10:44:48]

I don't expect that, it does not matter, we just reference these files from the
Manifest, not when we compile

[ricow1, 2013/02/19 10:45:58]

Yeah, I see why, sorry, will fix

I don't understand this input.

[ricow1, 2013/02/19 10:44:48]

Done, that is _not_ a input for this
