# DESCRIPTION
# Given a 'buildstats' path (created by bitbake when setting
# USER_CLASSES ?= "buildstats" on local.conf) and task names, outputs
# '<task> <recipe> <elapsed time>' for all recipes. Elapsed times are in
# seconds, and task should be given without the 'do_' prefix.
#
# Some useful pipelines
#
# 1. Tasks with largest elapsed times
# $ buildstats.sh -b <buildstats> | sort -k3 -n -r | head
#
# 2. Min, max, sum per task (in needs GNU datamash)
# $ buildstats.sh -b <buildstats> | datamash -t' ' -g1 min 3 max 3 sum 3 | sort -k4 -n -r
