20# DESCRIPTION
21#
22# Produces script data to be consumed by gnuplot. There are two possible plots
23# depending if either the -S parameter is present or not:
24#
25# * without -S: Produces a histogram listing top N recipes/tasks versus
26# stats. The first stat defined in the -s parameter is the one taken
27# into account for ranking
28# * -S: Produces a histogram listing tasks versus stats. In this case,
29# the value of each stat is the sum for that particular stat in all recipes found.
30# Stats values are in descending order defined by the first stat defined on -s
31#
32# EXAMPLES
33#
34# 1. Top recipes' tasks taking into account utime
35#
36# $ buildstats-plot.sh -s utime | gnuplot -p
37#
38# 2. Tasks versus utime:stime
39#
40# $ buildstats-plot.sh -s utime:stime -S | gnuplot -p
41#
42# 3. Tasks versus IO write_bytes:IO read_bytes
43#
44# $ buildstats-plot.sh -s 'IO write_bytes:IO read_bytes' -S | gnuplot -p
