+# 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

 # 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.
+# Given 'buildstats' data (generate by bitbake when setting
+# USER_CLASSES ?= "buildstats" on local.conf), task names and a stats values
+# (these are the ones preset on the buildstats files), outputs
+# '<task> <recipe> <value_1> <value_2> ... <value_n>'. The units are the ones
+# defined at buildstats, which in turn takes data from /proc/[pid] files
 #
 # Some useful pipelines
 #
-# 1. Tasks with largest elapsed times
-# $ buildstats.sh -b <buildstats> | sort -k3 -n -r | head
+# 1. Tasks with largest stime (Amount of time that this process has been scheduled
+#    in kernel mode) values
+# $ buildstats.sh -b <buildstats> -s stime | 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

+# module sizes for a built kernel, as a quick tool for comparing the
+# overall effects of systemic tinification changes.  Execute from the
+# base directory of the kernel build you want to summarize.  Setting
+# the 'verbose' flag will display the sizes for each file included in
+# the summary.
