- * Dumps the database.
|

|
- * It writes all of the database to standard output.
|
|
|
- * It uses gzip compression if compress is set in the URL/post data.
|
|
|
- * It may possibly time out, and mess up badly if you were relying on it. :P
|
|
|
- * The data dumped depends on whether "struct" and "data" are passed.
|
|
|
- * It requires an administrator and the session hash by post.
|
|
|
- * It is called from ManageMaintenance.php.
