DBUpgrade-Mechanismus: umgekehrte Abhängigkeiten mit »required_by« angeben können
Existierender Mechanismus mit »depends« sagt: die Scripte in »depends«
müssen ausgeführt werden, bevor ich selber ausgeführt werde.
Mit »required_by« kann man das Umgekehrte angeben: ich selber muss
ausgeführt werden, bevor die Scripte in »required_by« ausgeführt
werden können.
Damit kann man z.B. kundenspezifische SQL-Upgrades schreiben, die
erzwungen vor offiziellen SQL-Upgrades ausgeführt werden, ohne die
offiziellen Upgrade-Dateien dafür verändern zu müssen.
