|

2326 | |
|
|
2327 | Crossfire maintains a very simple database for extension use. It can |
|
|
2328 | currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to |
|
|
2329 | convert to/from binary). |
|
|
2330 | |
|
|
2331 | The parameter C<$family> should best start with the name of the extension |
|
|
2332 | using it, it should be unique. |
