2226
2227Crossfire maintains a very simple database for extension use. It can
2228currently store anything that can be serialised using Storable, which
2229excludes objects.
2230
2231The parameter C<$family> should best start with the name of the extension
2232using it, it should be unique.

2239
2240=item cf::db_put $family => $key => $value
