+# DESCRIPTION 'ksum.py' generates a combined summary of vmlinux and
+# 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.
