+## Beskrivelse
+Dette script er i kategorien "Udfases", da det er indbygget i image 5.0.0 og senere. Dvs. det er ikke længere nødvendigt at køre i nyere installationer, såfremt man bruger nyeste image.
+
+"Aktiverer" genveje på skrivebordet.
+
+Inden dette script køres kan man godt tilføje en genvej, men det rette ikon vil ikke dukke op, og programmet vil i stedet blive åbnet i et tekstredigeringsprogram.
+
+Der skal logges ud og ind igen - eller alternativt genstartes - før det tager effekt.
+Scriptet skal kun køres én gang - så virker genveje der er tilføjet til skrivebordet både før og efter.
+
+Dette script er blevet testet og virker på Ubuntu 22.04.
