Remove one space before "app"

What happens if this fails?

[knn, 2015/04/08 10:40:50]

The stamp file will not be written and build will stop.

[Bernhard Bauer, 2015/04/08 12:36:17]

What I meant to ask was, what happens if e.g. the directory is non-empty? I
assume we will throw an exception? Is that going to have an effect on the rest
of the build? Do we want to gracefully handle that case (if only to get a nicer
error message when this is an expected failure mode)?

[knn, 2015/04/08 12:52:54]

If the directory is not empty, we are packing junk resource files which
shouldn't be happening. I do not expect this script to run more than once with
the old resources. If someone manually fiddles with the temporary generated
files isn't it fair to expect them to clean up as well?
Since there should be no sane way to get to an non-empty directory, I am not
handling it. The error message is the only thing we know about the failure as
well.

[Bernhard Bauer, 2015/04/08 12:58:53]

Okay... I'm just worried that someone might rightfully add something here, and
then suddenly something would break, but I guess that's not going to be likely
if this is only temporary anyway.
