Tool to convert .brf to .txt and .txt to .brf?

Hey there.
Is there a tool to convert .brf to .txt and back again using liblouis?
I need liblouis because I need wide language support. For some reason Braille Blaster doesn't support all the liblouis tables, so that's not an option. I literally need a tool where I can give it a .brf or .txt, pick a braille table, hit convert.
