[Koha] Marc-import from text-file

Hello, I`m wondering how I could (,if it`s possible,) do Marc-imports from a text-file. I have about 1000 Marc-posts listet in a text-file seperated with the sign ^. I`ve read most of the guides I found on the KOHA documentation-site without getting any wiser regarding this kind of import procedure. All the best Kim Tallerås
