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

651# This function takes two files as arguments, obtains their diff, and
652# processes the diff output to present the files as an HTML document with
653# the files displayed side-by-side, differences shown in color.  It also
654# takes a delta comment, rendered as an HTML snippet, as the third
655# argument.  The function takes two files as arguments, then the name of
656# file, the path, and the comment.  The HTML will be delivered on stdout,
657# e.g.
658#
659#   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
660#         new/usr/src/tools/scripts/webrev.sh \
661#         webrev.sh usr/src/tools/scripts \
662#         '<a href="http://monaco.sfbay.sun.com/detail.jsp?cr=1234567">
663#          1234567</a> my bugid' > <file>.html
664#
665# framed_sdiff() is then called which creates $2.frames.html
666# in the webrev tree.
667#
668# FYI: This function is rather unusual in its use of awk.  The initial
669# diff run produces conventional diff output showing changed lines mixed
670# with editing codes.  The changed lines are ignored - we're interested in
671# the editing codes, e.g.
672#
673#      8c8
674#      57a61
675#      63c66,76
676#      68,93d80
677#      106d90
678#      108,110d91
679#
680#  These editing codes are parsed by the awk script and used to generate
681#  another awk script that generates HTML, e.g the above lines would turn
682#  into something like this:
683#
684#      BEGIN { printf "<pre>\n" }
685#      function sp(n) {for (i=0;i<n;i++)printf "\n"}
686#      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
687#      NR==8           {wl("#7A7ADD");next}
688#      NR==54          {wl("#7A7ADD");sp(3);next}
689#      NR==56          {wl("#7A7ADD");next}
690#      NR==57          {wl("black");printf "\n"; next}
691#        :               :
692#
693#  This script is then run on the original source file to generate the
694#  HTML that corresponds to the source file.
695#
696#  The two HTML files are then combined into a single piece of HTML that
697#  uses an HTML table construct to present the files side by side.  You'll
698#  notice that the changes are color-coded:
699#
700#   black     - unchanged lines
701#   blue      - changed lines
702#   bold blue - new lines
703#   brown     - deleted lines
704#
705#  Blank lines are inserted in each file to keep unchanged lines in sync
706#  (side-by-side).  This format is familiar to users of sdiff(1) or
707#  Teamware's filemerge tool.
