# DESCRIPTION
#
# Produces script data to be consumed by gnuplot. There are two possible plots
# depending if either the -S parameter is present or not:
#
# * without -S: Produces a histogram listing top N recipes/tasks versus
# stats. The first stat defined in the -s parameter is the one taken
# into account for ranking
# * -S: Produces a histogram listing tasks versus stats. In this case,
# the value of each stat is the sum for that particular stat in all recipes found.
# Stats values are in descending order defined by the first stat defined on -s
#
# EXAMPLES
#
# 1. Top recipes' tasks taking into account utime
#
# $ buildstats-plot.sh -s utime | gnuplot -p
#
# 2. Tasks versus utime:stime
#
# $ buildstats-plot.sh -s utime:stime -S | gnuplot -p
#
# 3. Tasks versus IO write_bytes:IO read_bytes
#
# $ buildstats-plot.sh -s 'IO write_bytes:IO read_bytes' -S | gnuplot -p

should be the same because data is plot as histogram.
