"""To use this you need to set the environment variable SUDO_ASKPASS to
/usr/sbin/sudopw (assuming that is where this script is installed), and
call sudo with the -A option.

For example:
export SUDO_ASKPASS=/usr/sbin/sudopw
sudo -A env

Of course you also need to set up your /etc/sudoers file so that the
user concerned is allowed to execute the desired programs (see the man
pages for sudo and sudoers).
