NAME
	$program - Make a tarball of the MySQL database files and upload it.

SYNOPSIS
	$program [OPTIONS]

DESCRIPTION

	This script creates a compressed tarball from the MySQL database files
	on disk, and uploads it to the ietf datatracker developer area on
	www.ietf.org.

	It is intended to be used with the docker datatracker environment, after
	you have set up the database with docker/setupdb, started the docker
	image with docker/run, and updated the database with docker/updatedb.  

	To use it, exit from the docker container, to make sure that mysqldb
	isn't running and all the files consistent and available for copy.  Then
	run docker/$program outside the docker container.  You need to have ssh
	access to www.ietf.org in order for the scp command to succeed.
