This is GIT 1.0-rc1 in disguise. It is plausible that relatively new parts of the system still need tweaking and fixing, but that is why it is not 1.0 but rc ;-). Signed-off-by: Junio C Hamano <junkio@cox.net>

+NAME
+----
+git-lost+found - Recover lost refs that luckily have not yet been pruned.
+
+SYNOPSIS
+--------
+'git-lost+found'
+
+DESCRIPTION
+-----------
+Finds dangling commits and tags from the object database, and
+creates refs to them in .git/lost-found/ directory. Commits and
+tags that dereference to commits go to .git/lost-found/commit
+and others are stored in .git/lost-found/other directory.
+
+
+OUTPUT
+------
+One line description from the commit and tag found along with
+their object name are printed on the standard output.
+
+
+EXAMPLE
+-------
+
+Suppose you run 'git tag -f' and mistyped the tag to overwrite.
+The ref to your tag is overwritten, but until you run 'git
+prune', it is still there.
