"""Reset a list's web_page_url attribute to the default setting.

This script is intended to be run as a bin/withlist script, i.e.

% bin/withlist -l -r fix_url listname [options]

Options:
    -u urlhost
    --urlhost=urlhost
        Look up urlhost in the virtual host table and set the web_page_url and
        host_name attributes of the list to the values found.  This
        essentially moves the list from one virtual domain to another.

        Without this option, the default web_page_url and host_name values are
        used.

    -v / --verbose
        Print what the script is doing.

If run standalone, it prints this help text and exits.
