+ * Notes:
+ * The initial adaptation from 4.4BSD Lite sources in September 1995 used 686
+ * lines from that version, and made changes/additions for 150 lines.  There
+ * was no reformatting, so with/without ignoring whitespace, the amount of
+ * change is the same.
+ *
+ * Comparing with current (2009) source, excluding this comment:
+ * a) 209 lines match identically to the 4.4BSD Lite sources, with 771 lines
+ *    changed/added.
+ * a) Ignoring whitespace, the current version still uses 516 lines from the
+ *    4.4BSD Lite sources, with 402 lines changed/added.
+ *
+ * Raymond's original comment on this follows...
