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

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

430# the files displayed side-by-side, differences shown in color.  It also
431# takes a delta comment, rendered as an HTML snippet, as the third
432# argument.  The function takes two files as arguments, then the name of
433# file, the path, and the comment.  The HTML will be delivered on stdout,
434# e.g.
435#
436#   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
437#         new/usr/src/tools/scripts/webrev.sh \
438#         webrev.sh usr/src/tools/scripts \
439#         '<a href="http://monaco.sfbay.sun.com/detail.jsp?cr=1234567">
440#          1234567</a> my bugid' > <file>.html
441#
442# framed_sdiff() is then called which creates $2.frames.html
443# in the webrev tree.
444#
445# FYI: This function is rather unusual in its use of awk.  The initial
446# diff run produces conventional diff output showing changed lines mixed
447# with editing codes.  The changed lines are ignored - we're interested in
448# the editing codes, e.g.
449#
450#      8c8
451#      57a61
452#      63c66,76
453#      68,93d80
454#      106d90
455#      108,110d91
456#
457#  These editing codes are parsed by the awk script and used to generate
458#  another awk script that generates HTML, e.g the above lines would turn
459#  into something like this:
460#
461#      BEGIN { printf "<pre>\n" }
462#      function sp(n) {for (i=0;i<n;i++)printf "\n"}
463#      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
464#      NR==8           {wl("#7A7ADD");next}
465#      NR==54          {wl("#7A7ADD");sp(3);next}
466#      NR==56          {wl("#7A7ADD");next}
467#      NR==57          {wl("black");printf "\n"; next}
468#        :               :
469#
470#  This script is then run on the original source file to generate the
471#  HTML that corresponds to the source file.
472#
473#  The two HTML files are then combined into a single piece of HTML that
474#  uses an HTML table construct to present the files side by side.  You'll
475#  notice that the changes are color-coded:
476#
477#   black     - unchanged lines
478#   blue      - changed lines
479#   bold blue - new lines
480#   brown     - deleted lines
481#
482#  Blank lines are inserted in each file to keep unchanged lines in sync
483#  (side-by-side).  This format is familiar to users of sdiff(1) or
484#  Teamware's filemerge tool.
