# sdiff_to_html
#
# This function takes two files as arguments, obtains their diff, and
# processes the diff output to present the files as an HTML document with
# the files displayed side-by-side, differences shown in color. It also
# takes a delta comment, rendered as an HTML snippet, as the third
# argument. The function takes two files as arguments, then the name of
# file, the path, and the comment. The HTML will be delivered on stdout,
# e.g.
#
# $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
# new/usr/src/tools/scripts/webrev.sh \
# webrev.sh usr/src/tools/scripts \
# '<a href="https://jbs.oracle.com/bugs/browse/JDK-1234567">
# JDK-1234567</a> my bugid' > <file>.html
#
# framed_sdiff() is then called which creates $2.frames.html
# in the webrev tree.
#
# FYI: This function is rather unusual in its use of awk. The initial
# diff run produces conventional diff output showing changed lines mixed
# with editing codes. The changed lines are ignored - we're interested in
# the editing codes, e.g.
#
# 8c8
# 57a61
# 63c66,76
# 68,93d80
# 106d90
# 108,110d91
#
# These editing codes are parsed by the awk script and used to generate
# another awk script that generates HTML, e.g the above lines would turn
# into something like this:
#
# BEGIN { printf "<pre>\n" }
# function sp(n) {for (i=0;i<n;i++)printf "\n"}
# function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
# NR==8 {wl("#7A7ADD");next}
# NR==54 {wl("#7A7ADD");sp(3);next}
# NR==56 {wl("#7A7ADD");next}
# NR==57 {wl("black");printf "\n"; next}
# : :
#
# This script is then run on the original source file to generate the
# HTML that corresponds to the source file.
#
# The two HTML files are then combined into a single piece of HTML that
# uses an HTML table construct to present the files side by side. You'll
# notice that the changes are color-coded:
#
# black - unchanged lines
# blue - changed lines
# bold blue - new lines
# brown - deleted lines
#
# Blank lines are inserted in each file to keep unchanged lines in sync
# (side-by-side). This format is familiar to users of sdiff(1) or
# Teamware's filemerge tool.

Options:
-v: Print the version of this tool.
-b: Do not ignore changes in the amount of white space.
-c <CR#>: Include link to CR (aka bugid) in the main page.
-O: Print bugids/arc cases suitable for OpenJDK.
-i <filename>: Include <filename> in the index.html file.
-o <outdir>: Output webrev to specified directory.
-p <compare-against>: Use specified parent wkspc or basis for comparison
-w <wxfile>: Use specified wx active file.
-u <username>: Use that username instead of 'guessing' one.
-m: Forces the use of Mercurial
-t: Forces the use of Teamware
Mercurial only options:
-r rev: Compare against a specified revision
-N: Skip 'hg outgoing', use only 'hg status'
-f: Use the forest extension
Environment:
WDIR: Control the output directory.
WEBREV_BUGURL: Control the URL prefix for bugids.
WEBREV_SACURL: Control the URL prefix for ARC cases.
SCM Environment:
