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:
62
63       body#SUNWwebrev span.removed { color: red ! important; }

591# sdiff_to_html
592#
593# This function takes two files as arguments, obtains their diff, and
594# processes the diff output to present the files as an HTML document with
595# the files displayed side-by-side, differences shown in color.  It also
596# takes a delta comment, rendered as an HTML snippet, as the third
597# argument.  The function takes two files as arguments, then the name of
598# file, the path, and the comment.  The HTML will be delivered on stdout,
599# e.g.
600#
601#   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
602#         new/usr/src/tools/scripts/webrev.sh \
603#         webrev.sh usr/src/tools/scripts \
604#         '<a href="http://monaco.sfbay.sun.com/detail.jsp?cr=1234567">
605#          1234567</a> my bugid' > <file>.html
606#
607# framed_sdiff() is then called which creates $2.frames.html
608# in the webrev tree.
609#
610# FYI: This function is rather unusual in its use of awk.  The initial
611# diff run produces conventional diff output showing changed lines mixed
612# with editing codes.  The changed lines are ignored - we're interested in
613# the editing codes, e.g.
614#
615#      8c8
616#      57a61
617#      63c66,76
618#      68,93d80
619#      106d90
620#      108,110d91
621#
622#  These editing codes are parsed by the awk script and used to generate
623#  another awk script that generates HTML, e.g the above lines would turn
624#  into something like this:
625#
626#      BEGIN { printf "<pre>\n" }
627#      function sp(n) {for (i=0;i<n;i++)printf "\n"}
628#      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
629#      NR==8           {wl("#7A7ADD");next}
630#      NR==54          {wl("#7A7ADD");sp(3);next}
631#      NR==56          {wl("#7A7ADD");next}
632#      NR==57          {wl("black");printf "\n"; next}
633#        :               :
634#
635#  This script is then run on the original source file to generate the
636#  HTML that corresponds to the source file.
637#
638#  The two HTML files are then combined into a single piece of HTML that
639#  uses an HTML table construct to present the files side by side.  You'll
640#  notice that the changes are color-coded:
641#
642#   black     - unchanged lines
643#   blue      - changed lines
644#   bold blue - new lines
645#   brown     - deleted lines
646#
647#  Blank lines are inserted in each file to keep unchanged lines in sync
648#  (side-by-side).  This format is familiar to users of sdiff(1) or
649#  Teamware's filemerge tool.
