59 to allow easy overriding by users of webrev via the userContent.css
60 mechanism available in some browsers.

63 brown, set a rule in your userContent.css file like:

624 # another awk script that generates HTML, e.g the above lines would turn
625 # into something like this:
626 #
627 # BEGIN { printf "<pre>\n" }
628 # function sp(n) {for (i=0;i<n;i++)printf "\n"}
629 # function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}

633 # NR==57 {wl("black");printf "\n"; next}

637 # HTML that corresponds to the source file.
638 #
639 # The two HTML files are then combined into a single piece of HTML that
640 # uses an HTML table construct to present the files side by side. You'll
641 # notice that the changes are color-coded:
642 #
643 # black - unchanged lines
644 # blue - changed lines
645 # bold blue - new lines
646 # brown - deleted lines
647 #
648 # Blank lines are inserted in each file to keep unchanged lines in sync
649 # (side-by-side). This format is familiar to users of sdiff(1) or
650 # Teamware's filemerge tool.
