Firebird QLI scripts documentation

Does someome have any links or documentation for qli.exe?

I recently used qli.exe scripts for fixing BD structure corruption as described in this article , since then and I’ve been searching for information about qli commands or scripts but it seems not to be so much information about it.

Near the bottom of this page is a download link for the qli syntax document from InterBase 3.  Qli hasn’t changed.

Update: QLI is deprecated and unsupported fore firebird > 2
