# NAME
#     xbuildgen - Generate build results across multiple platforms.
#
# SYNOPSIS
#     xbuildgen [option(s)...] [log-file(s)...]
#
# DESCRIPTION
#     The xbuildgen utility generates a build result in HTML format
#     across multiple platforms or tests with builds in columns and
#     components such as examples, locales, and tests in rows by
#     default.
#
# OPTIONS
#     -n   No clean. Avoid removing temporary files.
#
#     -s   Stylesheet. Create a style sheet named resultstyle.css in
#          the same directory as the output file when the -o option
#          is specified, or in the current working directory otherwise.
#
#     -v   Verbose. Produce verbose output on stdout.
#
#     -e <list-of-examples>
#          Generate a report for the specified list of example programs
#          with examples listed in columns and builds in rows.
#
#     -h   Print help.
#
#     -l <list-of-locales>
#          Generate a report for the specified list of locales with
#          locales listed in columns and builds in rows.
#
#     -o <output-file>
#          Specify the pathname of the output file. The utility will
#          use stdout when no output file is specified.
#
#     -T <text>
#          Specify the title for the page.
#
#     -t <list-of-tests>
#          Generate a report for the specified list of tests with
#          tests listed in columns and builds in rows.
