+#
+# framed_sdiff() is then called which creates $2.frames.html
+# in the webrev tree.
+#
+# FYI: This function is rather unusual in its use of awk.  The initial
+# diff run produces conventional diff output showing changed lines mixed
+# with editing codes.  The changed lines are ignored - we're interested in
+# the editing codes, e.g.
+#
+#      8c8
+#      57a61
+#      63c66,76
+#      68,93d80
+#      106d90
+#      108,110d91
+#
+#  These editing codes are parsed by the awk script and used to generate
+#  another awk script that generates HTML, e.g the above lines would turn
+#  into something like this:
+#
+#      BEGIN { printf "
\n" }
+#      function sp(n) {for (i=0;i%4d %s \n", n, NR, $0}
+#      NR==8           {wl("#7A7ADD");next}
+#      NR==54          {wl("#7A7ADD");sp(3);next}
+#      NR==56          {wl("#7A7ADD");next}
+#      NR==57          {wl("black");printf "\n"; next}
+#        :               :
+#
+#  This script is then run on the original source file to generate the
+#  HTML that corresponds to the source file.
+#
+#  The two HTML files are then combined into a single piece of HTML that
+#  uses an HTML table construct to present the files side by side.  You'll
+#  notice that the changes are color-coded:
+#
+#   black     - unchanged lines
+#   blue      - changed lines
+#   bold blue - new lines
+#   brown     - deleted lines
+#
+#  Blank lines are inserted in each file to keep unchanged lines in sync
+#  (side-by-side).  This format is familiar to users of sdiff(1) or
+#  Teamware's filemerge tool.
