[Doxygen-users] feature request: add support for fragmented \dot digraph stat emachine diagrams

[<Ced...@ec...>]

­I'm using doxygen to create state machine diagrams from my C code. This works great, I can create a comment block like this, run doxygen / graphwiz, and get a html file with the diagram:

/*!
  \dot
   digraph my_state_machine {
	rankdir=LR;
	size="8,5"

    init -> start [ label = "" ];
    start -> continue [ label = "" ];
    continue -> stop[ label = "" ];
    stop -> start [ label = "" ]; }
    \enddot
 */

Now I would like to be able in interleave doxygen comments with my code, so the documentation and the corresponding code are closer together. I would like to split the above diagram like this:

/*! \dot digraph my_state_machine { rankdir=LR; size="8,5" } \enddot */
uint8_t mystate = ST_INIT;
while 1
{
	switch (myState)
	{
		case ST_INIT:
		{
			/*! \dot digraph my_state_machine { init -> start [ label = "" ]; } \enddot */
			myState = ST_START;
			break;
		}
		case ST_START:
		{
			/*! \dot digraph my_state_machine { start -> continue [ label = "" ]; } \enddot */
			myState = ST_CONTINUE;
			break;
		}
		case ST_CONTINUE:
		{
			/*! \dot digraph my_state_machine { continue -> stop [ label = "" ]; } \enddot */
			myState = ST_STOP;
			break;
		}
		case ST_STOP:
		{
			/*! \dot digraph my_state_machine { stop -> start [ label = "" ]; } \enddot */
			myState = ST_START;
			break;
		}
	}
}

Is there any filter that can take fragments of the digraph diagram, assemble it, and then feed it to doxygen, so doxygen can feed it into graphwiz/dot?
Can doxygen be extended to be able to assemble \dot fragments?
