-"""
-Execute tasks through strace to obtain dependencies after the process is run. This
-scheme is similar to that of the Fabricate script.
-
-To use::
-
-  def configure(conf):
-     conf.load('strace')
-
-WARNING:
-* This will not work when advanced scanners are needed (qt4/qt5)
-* The overhead of running 'strace' is significant (56s -> 1m29s)
-* It will not work on Windows :-)
