From 264244a0429e23616a6065f6f52a15711981a8db Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Fri, 25 Aug 2006 23:07:06 -0400 Subject: [PATCH] Added --branch-log to option to fast-import. This option can be used to have a record of every commit, the mark (if supplied) and branch name of the commit recorded into a log file when the commit is generated. This log can be useful to verify the results of an import as the commits can be compared to some source repository matching commits through the mark value. Signed-off-by: Shawn O.
