+
+# This makefile takes raw data files named ``winEmbed.dat'' and
+# ``mozilla.dat'' produces a graph that shows memory usage and peak
+# memory usage versus number of URLs loaded.
+#
+# The data files are assumed to be of the form:
+#
+#   <working-set-size-1> <peak-working-set-size-1>
+#   <working-set-size-2> <peak-working-set-size-2>
+#   ...
+#
+# It is also assumed that each measurement corresponds (roughly) to a
+# URL load.
+#
+# You can tweak ``win32.gnuplot.in'' to change the graph's output.
+#
+# You should use this with ``make --unix'' (which will use
+# sh.exe instead of cmd.exe to process commands); e.g.,
+#
+#   make --unix -f win32-gdf.mk \
+#     BUSTER_URL="http://localhost/cgi-bin/buster.cgi?refresh=10"
+#
+# What You'll Need
+# ----------------
+#
+# . Get gnuplot for Win32 from
+#
+#     ftp://ftp.dartmouth.edu/pub/gnuplot/gnuplot3.7cyg.zip
+#
+# . The "standard" cygwin tools that you probably already have. (If
+#   you don't have 'em, see the Win32 build instructions on
+#   mozilla.org.)
+#
+
+# This script computes a line using linear regression; its output is
+# of the form:
+#
+#   <b1> * x + <b0>
+#
+# Where <b1> is the slope and <b0> is the y-intercept.
