michael@0: # This makefile takes raw data files named ``winEmbed.dat'' and
michael@0: # ``mozilla.dat'' produces a graph that shows memory usage and peak
michael@0: # memory usage versus number of URLs loaded.
michael@0: #
michael@0: # The data files are assumed to be of the form:
michael@0: #
michael@0: #   <working-set-size-1> <peak-working-set-size-1>
michael@0: #   <working-set-size-2> <peak-working-set-size-2>
michael@0: #   ...
michael@0: #
michael@0: # It is also assumed that each measurement corresponds (roughly) to a
michael@0: # URL load.
michael@0: #
michael@0: # You can tweak ``win32.gnuplot.in'' to change the graph's output.
michael@0: #
michael@0: # You should use this with ``make --unix'' (which will use
michael@0: # sh.exe instead of cmd.exe to process commands); e.g.,
michael@0: #
michael@0: #   make --unix -f win32-gdf.mk \
michael@0: #     BUSTER_URL="http://localhost/cgi-bin/buster.cgi?refresh=10"

michael@0: # What You'll Need
michael@0: # ----------------
michael@0: #
michael@0: # . Get gnuplot for Win32 from
michael@0: #
michael@0: #     ftp://ftp.dartmouth.edu/pub/gnuplot/gnuplot3.7cyg.zip
michael@0: #
michael@0: # . The "standard" cygwin tools that you probably already have. (If
michael@0: #   you don't have 'em, see the Win32 build instructions on
michael@0: #   mozilla.org.)
michael@0: #
michael@0: 
michael@0: # This script computes a line using linear regression; its output is
michael@0: # of the form:
michael@0: #
michael@0: #   <b1> * x + <b0>
michael@0: #
michael@0: # Where <b1> is the slope and <b0> is the y-intercept.
