SYNOPSIS

DESCRIPTION
-----------
@@ -25,6 +25,11 @@ OPTIONS
Allow missing objects. The default behaviour (without this option)
is to verify that each tree entry's sha1 identifies an existing
object.
+--batch::
+ Allow building of more than one tree object before exiting. Each
+ tree is separated by as single blank line. The final new-line is
+ optional. Note - if the '-z' option is used, lines are terminated
+ with NUL.
