documentation directories, and won't be confused with virtual machines.

-#
-# Use `slabinfo-gnuplot.sh stats' to pre-process collected records

-#
-# Graphs can be [individually] regenerate with different ranges and

-# To visually compare N `totals' graphs, do
-# slabinfo-gnuplot.sh -t FILE1-totals FILE2-totals ... FILEN-totals
