-# do_package_write_*, causing them to be written into a different
-# directory where we can compare them to whatever older packages might
-# be in the "real" package feed directory, and avoid copying the new
-# package to the feed if it has not materially changed. The idea is to
-# avoid unnecessary churn in the packages when dependencies trigger task
-# reexecution (and thus repackaging). Enabling the class is simple:
-#
-# INHERIT += "packagefeed-stability"
-#
-# Caveats:
-# 1) Latest PR values in the build system may not match those in packages
-#    seen on the target (naturally)
-# 2) If you rebuild from sstate without the existing package feed present,
-#    you will lose the "state" of the package feed i.e. the preserved old
-#    package versions. Not the end of the world, but would negate the
-#    entire purpose of this class.
-#
-# Note that running -c cleanall on a recipe will purposely delete the old
-# package files so they will definitely be copied the next time.
