	No tools are present that I know of, but using a little Perl/CGI
or PHP to execute passwd is pretty simple. Just be sure to use a series
of checks so people don't send in chars that can be interpreted for
execution or have special purpose uses by shells.

Don't suggest this solution as it is insecure, but it's an example:

Don't remember how to change the password using command line arguments
either, but I know it can be done somehow (pw? passwd?), some way..
