All standard applications delivered in with Orfeo ToolBox comes with simplified scripts in the system path, allowing to launch the command-line and graphical user interface versions of the application in the same simple way we used to launch the old applications. The command-line interface is prefixed by otbcli_, while the Qt interface is prefixed by otbgui_. For instance, calling otbcli_Convert will launch the command-line interface of the Convert application, while otbgui_Convert will launch its GUI.
Passing arguments to the command-line version (prefixed by otbcli_) is explained in next sub-section.
