# This shell script takes two `object histograms' produced using
|
|
# `histogram.pl' and prints the delta, sorted such that the objects
|
|
# that increased the most in raw memory usage are displayed at the
|
|
# top.
|
|

|
|
# Usage:
|
|
#
|
|
# histogram-pretty.sh [-c <count>] [-w <width>] <file>
|
|
#
|
|
# Pretty-print the histogram in file <file>, displaying at most
|
|
# <count> rows.

# How many rows are we gonna show?
