[PATCH] Simplified the invocation of command action in submodule

[imyousuf@gmail.com]

From: Imran M Yousuf <imran@smartitengineering.com>

- Simplified the invocation of action.
- Changed switch case based action invoke rather more direct command
invocation. Previously first switch case was used to go through $@ and
determine the action, i.e. add, init, update etc, and second switch case
just to invoke the action. It is modified to determine the action name in
the first case structure instead and later just invoke it.
