Hi Yarn list,

Apologies if this is a simple question. I have just subscribed to another
list that is controlled by majordomo software. The messages are archived
and I have fetched them all so that now I have a large ascii file
containing a number of messages. I wondered if there was a nifty little
utility that could convert this file into a yarn folder so that I could
read the messages with my favourite mail reader.

Thanks,
Ian
