To provide metadata from svn dumps for further processing, e.g. branch detection, attach a note to each imported commit that stores additional information. The notes are currently hard-coded in refs/notes/svn/revs. Currently the following lines from the svn dump are directly accumulated in the note. This can be refined on purpose, of course. - "Revision-number" - "Node-path" - "Node-kind" - "Node-action" - "Node-copyfrom-path" - "Node-copyfrom-rev"
