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

955# argument.  The function takes two files as arguments, then the name of
956# file, the path, and the comment.  The HTML will be delivered on stdout,
957# e.g.
958#
959#   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
960#         new/usr/src/tools/scripts/webrev.sh \

963#          1234567</a> my bugid' > <file>.html
964#
965# framed_sdiff() is then called which creates $2.frames.html
966# in the webrev tree.
967#
968# FYI: This function is rather unusual in its use of awk.  The initial
969# diff run produces conventional diff output showing changed lines mixed
970# with editing codes.  The changed lines are ignored - we're interested in
971# the editing codes, e.g.
972#
973#      8c8
974#      57a61
975#      63c66,76
976#      68,93d80
977#      106d90
978#      108,110d91
979#
980#  These editing codes are parsed by the awk script and used to generate
981#  another awk script that generates HTML, e.g the above lines would turn
982#  into something like this:
983#
984#      BEGIN { printf "<pre>\n" }
985#      function sp(n) {for (i=0;i<n;i++)printf "\n"}
986#      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
987#      NR==8           {wl("#7A7ADD");next}
988#      NR==54          {wl("#7A7ADD");sp(3);next}
989#      NR==56          {wl("#7A7ADD");next}
990#      NR==57          {wl("black");printf "\n"; next}
991#        :               :
992#
993#  This script is then run on the original source file to generate the
994#  HTML that corresponds to the source file.
995#
996#  The two HTML files are then combined into a single piece of HTML that
997#  uses an HTML table construct to present the files side by side.  You'll
998#  notice that the changes are color-coded:
999#
1000#   black     - unchanged lines
1001#   blue      - changed lines
1002#   bold blue - new lines
1003#   brown     - deleted lines
1004#
1005#  Blank lines are inserted in each file to keep unchanged lines in sync
1006#  (side-by-side).  This format is familiar to users of sdiff(1) or
1007#  Teamware's filemerge tool.
