2170	Crossfire maintains a very simple database for extension use. It can
2171	currently store anything that can be serialised using Storable, which
2172	excludes objects.
2173
2174	The parameter C<$family> should best start with the name of the extension
2175	using it, it should be unique.

2181	Return a hashref for use by the extension C<$family>, which can be
2182	modified. After modifications, you have to call C<cf::db_dirty> or
2183	C<cf::db_sync>.
2184

2186

2188

2191	Stores the given family hashref into the database. Updates are delayed, if
2192	you want the data to be synced to disk immediately, use C<cf::db_sync>.
2193
