+Options:
+ -h
+ Display this help and exit.
+ -c <commit>
+ git checkout <commit> before anything else
+ -v
+ Show bitbake output, don't redirect it to a log.
+ -m <machine>
+ Value for MACHINE. Default is qemux86.
+ -j <val>
+ Value for PARALLEL_MAKE. Default is 8.
+ -t <val>
+ Value for BB_NUMBER_THREADS. Default is 8.
+ -i <image-name>
+ Instead of timing against core-image-sato, use <image-name>
+ -d <path>
+ Use <path> as DL_DIR
+ -p <githash>
+ Cherry pick githash onto the commit
+
+Note: current working directory must be inside a poky git clone.
