$prog:  Uploads binary packages.

Usage:  $prog [-c|--config <file>] [-n|--no-upload] [-d|--debug] [-v|--verbose]
	$prog -h|--help
        $prog -V|--version

    -c | --config <file>
			Load the following configuration file instead of
			the default one.

    -d|--debug          Preserves some intermediate files to help
			debug any problems.

    -h|--help           Displays this help message and exits.

    -n|--no-upload      Does all of the work except for the actual upload.
			This option may be used to generate the upload script
			along with the list of packages to be excluded.

    -i|--no-install	Do not install the required packages; assume instead
			that they are already available.

    -v|--verbose        Enables verbose output.

    -V|--version        Displays the version of this script and exits.

Example:

    cd /usr/pkgsrc && $prog

Environment Variables:

    AWK  --  If specified, sets the awk program to be used

Files:

    pkgsrc/mk/bulk/build.conf
