Some minor patch-header cleanup.

[rsync/rsync-patches.git] / source-cd.diff

This adds the --source-cd option, which is useful when it is combined with
the --relative option because it lets you set how much of the source path
is outside of the transfer.  For instance:

rsync -avR --source-cd=/usr local/bin host:/

For two systems where one uses /usr/local/bin and the other /local/bin.
