I have one nnml group with about 30,000 messages in it.  I'd like to split
it by year into different groups (e.g., nnml:stuff1998, nnml:stuff1999,
etc.).  Is there some way to do that which:

1) I can start running and leave overnight or something?  Unless it's *very*
fast, it will take a long time to process all these messages.

2) Will keep the the .overview file(s) correct in all groups?

Thanks,

-pd
