Long line.

[kustermann, 2012/12/05 09:08:53]

Done.

+            # the action doesn't get executed if any of libdart/libdart_withcore

[ahe, 2012/12/04 15:33:58]

It is not only libdart/libdart_withcore.

Also, the sentence is a bit convoluted, you could try something like this:

"Depend on libdart_dependency_helper to track the libraries it depends on".

Done.
