62   Note to customizers: the body of the webrev is IDed as SUNWwebrev
63   to allow easy overriding by users of webrev via the userContent.css
64   mechanism available in some browsers.
65
66   For example, to have all "removed" information be red instead of
67   brown, set a rule in your userContent.css file like:
68
69       body#SUNWwebrev span.removed { color: red ! important; }

238# This function takes two files as arguments, obtains their diff, and
239# processes the diff output to present the files as an HTML document with
240# the files displayed side-by-side, differences shown in color.  It also
241# takes a delta comment, rendered as an HTML snippet, as the third
242# argument.  The function takes two files as arguments, then the name of
243# file, the path, and the comment.  The HTML will be delivered on stdout,
244# e.g.
245#
246#   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
247#         new/usr/src/tools/scripts/webrev.sh \
248#         webrev.sh usr/src/tools/scripts \
249#         '<a href="http://monaco.sfbay.sun.com/detail.jsp?cr=1234567">
250#          1234567</a> my bugid' > <file>.html
251#
252# framed_sdiff() is then called which creates $2.frames.html
253# in the webrev tree.
254#
255# FYI: This function is rather unusual in its use of awk.  The initial
256# diff run produces conventional diff output showing changed lines mixed
257# with editing codes.  The changed lines are ignored - we're interested in
258# the editing codes, e.g.
259#
260#      8c8
261#      57a61
262#      63c66,76
263#      68,93d80
264#      106d90
265#      108,110d91
266#
267#  These editing codes are parsed by the awk script and used to generate
268#  another awk script that generates HTML, e.g the above lines would turn
269#  into something like this:
270#
271#      BEGIN { printf "<pre>\n" }
272#      function sp(n) {for (i=0;i<n;i++)printf "\n"}
273#      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
274#      NR==8           {wl("#7A7ADD");next}
275#      NR==54          {wl("#7A7ADD");sp(3);next}
276#      NR==56          {wl("#7A7ADD");next}
277#      NR==57          {wl("black");printf "\n"; next}
278#        :               :
279#
280#  This script is then run on the original source file to generate the
281#  HTML that corresponds to the source file.
282#
283#  The two HTML files are then combined into a single piece of HTML that
284#  uses an HTML table construct to present the files side by side.  You'll
285#  notice that the changes are color-coded:
286#
287#   black     - unchanged lines
288#   blue      - changed lines
289#   bold blue - new lines
290#   brown     - deleted lines
291#
292#  Blank lines are inserted in each file to keep unchanged lines in sync
293#  (side-by-side).  This format is familiar to users of sdiff(1) or
294#  Teamware's filemerge tool.
