Hi,

Just to remind the context, I'm pasting content from previous mail thread.

I've added implementation of rotating file collector -
the patch against boost log trunk attached.
This is not the final version, I'm going at least to finish most of the TODOs.

However, it would be nice to receive feedback and questions from
library author as well as from people interested in this feature.

Andrey, could you please find several minutes to review the attached patch?

Also, I would like to discuss following question with you :
rotate_file invocation in ~text_file_backend -
I would prefer to have this call during text_file_backend construction phase.

Regards
