+# http://git.yoctoproject.org/cgit/cgit.cgi/meta-mentor/log/classes/buildstats-summary.bbclass
+# with following modifications
+# 1) when both setscene and normal tasks were executed, count it as no_sstate
+# 2) count do_populate_sysroot and do_packagedata tasks, because often we invalidate only runtime deps
