[Koha] MARC records

Hi.. I found Koha while searching for GPL software to use in a scalable way in my son's school library... I have to say I was much impressed with Koha. Does anyone know if Koha supports MARC records... this was a question that came up. I realize there is a perl (ariadne) project dealing with MARC, but since I have little experience with Koha or Ariadne, I didn't know if this was supported. Infact, I only recently learned of the existance of MARC records, so I'm not sure if this is appropriate. Also, is anyone providing paid support for Koha? Mike
