This package forces the use of Google and Bing safe search by default.
It does this by adding hosts files for dnsmasq to use. These hosts replace the
normal IP addresses for Google and Bing with addresses that force safe
search to be turned on all the time.

Google and Bing Safe Search are suitable for most businesses, schools, and
families who wish to block adult content. This package also offers
YouTube's restricted and 'restricted moderate' via a configuration
option. The reason that this is not enabled is that it is probably more
suitable for children rather than a wide audience.

This package is designed so that other services that offer safe search can be
added easily in the future.
