Svn help mergeinfo does not reference --reintegrate at all. Are you
saying that a merge with the
-reintegrate option may skip some items that mergeinfo lists as
eligible?

Also the help for reintegrate says that the only difference is that it
treats the merge as a lump sum, not as a sequence of mini merges. Are
you saying that if you have done a complete merge out, you can skip the
individual merge ins and just do one big reintegrate? If so, Is doing a
complete merge out first mandatory? (I would think so). Can this model
handle files that were deleted and re-added?

Actually, now that I have written and reread this, I think I answered my
own question. Using reintegrate is orthogonal to using mergeinfo. You
use mergeinfo to pick up changes that have been made in a release branch
that need to be merged to trunk, and you use -reintegrate to merge a
project branch back to its baseline.

I feel like I must have missed that section in the book. Is this not
documented?

Thanks
