 	Path to submodule(s). When specified this will restrict the command
 	to only operate on the submodules found at the specified paths.
 
+-e, --exit-after-error::

+	then command will not be recursed into any other module once a command
+	has failed
+-d, --depth <recursion depth>::
+	This option is only valid for the recurse command. If its provided then
+	then the command will be recursed upto <recursion depth> only.
+-b, --breadth-first::
+	This option is only valid for the recurse command. If its provided then

+	child, else it will first traverse the children before executing in the
+	current node.
+-a, --customized-argument::
+	This option is only valid for the recurse command. If its provided then
+	user will be prompted for an argument for the <git command> specified.
+	Its particularly useful when one wants to supply different arguments

+	checking out a branch, one might want branch to differ from submodule
+	to submodule
+-p, --pre-command::
+	This option is only valid for the recurse command. If its provided then
+	user will be prompted for a shell command, e.g. 'ls -al', 'pwd' etc.
+<git command> [<arg>...]::
+	Any git command and their argument. For example, to get the status use
