2128Crossfire maintains a very simple database for extension use. It can 2653 warn "loading facedata from $path\n";
2129currently store anything that can be serialised using Storable, which
2130excludes objects.
2131 2654
2132The parameter C<$family> should best start with the name of the extension 2655 my $facedata;
2133using it, it should be unique. 2656 0 < aio_load $path, $facedata

2139Return a hashref for use by the extension C<$family>, which can be
