Extract data from a Btrieve database?

I have a site that has a NetWare 6.5 server they've been hanging onto because it has old accounting data on it required for archival purposes. The accounting software is Platinum and uses a Btrieve database. I'm trying to find some way to extract the data out of the database so I can get rid of the NetWare server. Does anyone have any tools/advise as to how to archive the data in the Btrieve DB? Thanks.
