56   Note to customizers: the body of the webrev is IDed as SUNWwebrev
57   to allow easy overriding by users of webrev via the userContent.css
58   mechanism available in some browsers.
59
60   For example, to have all "removed" information be red instead of
61   brown, set a rule in your userContent.css file like:

234# sdiff_to_html
235#
236# This function takes two files as arguments, obtains their diff, and
237# processes the diff output to present the files as an HTML document with
238# the files displayed side-by-side, differences shown in color.  It also
239# takes a delta comment, rendered as an HTML snippet, as the third
240# argument.  The function takes two files as arguments, then the name of
241# file, the path, and the comment.  The HTML will be delivered on stdout,
242# e.g.
243#
244#   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
245#         new/usr/src/tools/scripts/webrev.sh \
246#         webrev.sh usr/src/tools/scripts \
247#         '<a href="http://monaco.sfbay.sun.com/detail.jsp?cr=1234567">
248#          1234567</a> my bugid' > <file>.html
249#
250# framed_sdiff() is then called which creates $2.frames.html
251# in the webrev tree.
252#
253# FYI: This function is rather unusual in its use of awk.  The initial
254# diff run produces conventional diff output showing changed lines mixed
255# with editing codes.  The changed lines are ignored - we're interested in
256# the editing codes, e.g.
257#
258#      8c8
259#      57a61
260#      63c66,76
261#      68,93d80
262#      106d90
263#      108,110d91
264#
265#  These editing codes are parsed by the awk script and used to generate
266#  another awk script that generates HTML, e.g the above lines would turn
267#  into something like this:
268#
269#      BEGIN { printf "<pre>\n" }
270#      function sp(n) {for (i=0;i<n;i++)printf "\n"}
271#      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
272#      NR==8           {wl("#7A7ADD");next}
273#      NR==54          {wl("#7A7ADD");sp(3);next}
274#      NR==56          {wl("#7A7ADD");next}
275#      NR==57          {wl("black");printf "\n"; next}
276#        :               :
277#
278#  This script is then run on the original source file to generate the
279#  HTML that corresponds to the source file.
280#
281#  The two HTML files are then combined into a single piece of HTML that
282#  uses an HTML table construct to present the files side by side.  You'll
283#  notice that the changes are color-coded:
284#
285#   black     - unchanged lines
286#   blue      - changed lines
287#   bold blue - new lines
288#   brown     - deleted lines
289#
290#  Blank lines are inserted in each file to keep unchanged lines in sync
291#  (side-by-side).  This format is familiar to users of sdiff(1) or
292#  Teamware's filemerge tool.
