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; }

714# This function takes two files as arguments, obtains their diff, and

716# the files displayed side-by-side, differences shown in color.  It also
717# takes a delta comment, rendered as an HTML snippet, as the third
718# argument.  The function takes two files as arguments, then the name of
719# file, the path, and the comment.  The HTML will be delivered on stdout,
720# e.g.
721#
722#   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
723#         new/usr/src/tools/scripts/webrev.sh \
724#         webrev.sh usr/src/tools/scripts \
725#         '<a href="http://monaco.sfbay.sun.com/detail.jsp?cr=1234567">
726#          1234567</a> my bugid' > <file>.html
727#
728# framed_sdiff() is then called which creates $2.frames.html
729# in the webrev tree.
730#
731# FYI: This function is rather unusual in its use of awk.  The initial
732# diff run produces conventional diff output showing changed lines mixed
733# with editing codes.  The changed lines are ignored - we're interested in
734# the editing codes, e.g.
735#
736#      8c8
737#      57a61
738#      63c66,76
739#      68,93d80
740#      106d90
741#      108,110d91
742#
743#  These editing codes are parsed by the awk script and used to generate
744#  another awk script that generates HTML, e.g the above lines would turn
745#  into something like this:
746#
747#      BEGIN { printf "<pre>\n" }
748#      function sp(n) {for (i=0;i<n;i++)printf "\n"}
749#      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
750#      NR==8           {wl("#7A7ADD");next}
751#      NR==54          {wl("#7A7ADD");sp(3);next}
752#      NR==56          {wl("#7A7ADD");next}
753#      NR==57          {wl("black");printf "\n"; next}
754#        :               :
755#
756#  This script is then run on the original source file to generate the
757#  HTML that corresponds to the source file.
758#
759#  The two HTML files are then combined into a single piece of HTML that
760#  uses an HTML table construct to present the files side by side.  You'll
761#  notice that the changes are color-coded:
762#
763#   black     - unchanged lines
764#   blue      - changed lines
765#   bold blue - new lines
766#   brown     - deleted lines
767#
768#  Blank lines are inserted in each file to keep unchanged lines in sync
769#  (side-by-side).  This format is familiar to users of sdiff(1) or
770#  Teamware's filemerge tool.
