-description "Temporary, quick-hack metrics collection & thermal daemon"
-author "chromium-os-dev@chromium.org"
-
-# This is for quickly adding UMA stats that we may need for
-# short-term experiments, when we don't have the time to add
-# stuff to metrics_daemon. That's where it should go in the
-# long term.
-#
-# This is also currently doing a userland thermal loop to allow
-# for quick experimentation. This thermal loop will eventually
-# move to the BIOS once the data from experiments help prove its
-# efficacy.
