 	in the submodule between the given super project commit and the
 	index or working tree (switched by --cached) are shown.
 
+foreach::
+	Evaluates an arbitrary shell command in each checked out submodule.
+	The command has access to the variables $path and $sha1:
+	$path is the name of the submodule directory relative to the
+	superproject, and $sha1 is the commit as recorded in the superproject.
+	Any submodules defined in the superproject but not checked out are
+	ignored by this command. Unless given --quiet, foreach prints the name
+	of each submodule before evaluating the command.
+	A non-zero return from the command in any submodule causes
+	the processing to terminate. This can be overridden by adding '|| :'
+	to the end of the command.
++
+As an example, "git submodule foreach 'echo $path `git rev-parse HEAD`' will
+show the path and currently checked out commit for each submodule.
+
+sync::
+	Synchronizes submodules' remote URL configuration setting
+	to the value specified in .gitmodules.  This is useful when
+	submodule URLs change upstream and you need to update your local
+	repositories accordingly.
++
+"git submodule sync" synchronizes all submodules while
+"git submodule sync -- A" synchronizes submodule "A" only.
