2176	=head2 EXTENSION DATABASE SUPPORT
2177
2178	Crossfire maintains a very simple database for extension use. It can
2179	currently store anything that can be serialised using Storable, which
2180	excludes objects.
2181
2182	The parameter C<$family> should best start with the name of the extension
2183	using it, it should be unique.
2184
2185	=over 4
2186
2187	=item $hashref = cf::db_get $family
2188
2189	Return a hashref for use by the extension C<$family>, which can be
2190	modified. After modifications, you have to call C<cf::db_dirty> or
2191	C<cf::db_sync>.
2192
2193	=item $value = cf::db_get $family => $key
2194
2195	Returns a single value from the database
2196
2197	=item cf::db_put $family => $hashref
2198
2199	Stores the given family hashref into the database. Updates are delayed, if
2200	you want the data to be synced to disk immediately, use C<cf::db_sync>.
2201
2202	=item cf::db_put $family => $key => $value
2203
2204	Stores the given C<$value> in the family hash. Updates are delayed, if you
2205	want the data to be synced to disk immediately, use C<cf::db_sync>.
2206
2207	=item cf::db_dirty
2208
2209	Marks the database as dirty, to be updated at a later time.
2210
2211	=item cf::db_sync
