/** @defgroup _fsm_flow FSM Flow Chart
 *  @ingroup _enum_fsm
 *  @brief This flow chart shows how the FSM works

There are the following steps the OCG module should contain :
- start OCG
- get option
- detect file
- initiate an emulation
- parse filename
- create directory
- parse XML
- save XML
- call OAI emulator
- generate report
- end OCG

The following diagram is based on graphviz (http://www.graphviz.org/), you need to install the package to view the diagram.
