/**
 * transport is a simple program that creates a message, explicitly
 * retrieves a Transport from the session based on the type of the
 * address (it's InternetAddress, so SMTP will be used) and sends 
 * the message.
 *
 * usage: <code>java transport <i>"toaddr1[, toaddr2]*"  from smtphost 
 * true|false</i></code><br>
 * where <i>to</i> and <i>from</i> are the destination and
 * origin email addresses, respectively, and <i>smtphost</i>
 * is the hostname of the machine that has the smtp server
 * running. The <i>to</i> addresses can be either a single email
 * address or a comma-separated list of email addresses in
 * quotes, i.e. "joe@machine, jane, max@server.com"
 * The last parameter either turns on or turns off
 * debugging during sending.
