"""Check a tagged (dated, or sender style only) e-mail address.

Usage:  %(program)s [-c <file>] [-V] [-h] address [senderaddr]

Where:
    -c <file>
    --config-file <file>
       Specify a different configuration file other than ~/.tmda/config.
       
    -l
    --localtime
       Display dates in the local time zone instead of UTC.

    -V
    --version
       Print TMDA version information and exit.

    --help
    -h
       Print this help message and exit.

    address is the address you want to check.
    
    senderaddr is the sender address to verify if checking a sender style address.
