Serialize a vector of lists with boost

[caneta]

Hi all.
I have a program, simplified as follows:

#include <vector>
#include <list>
#include <fstream>

using namespace std;

class MyObj
{
	int val;

	public:
	MyObj(int v){ val = v; };
	~MyObj(){};
};

int main (int argc, char *argv[])
{
	int i, j;
	vector< list<MyObj*> > layers;

	for(i=0; i<5; i++)
	{
		list<MyObj*> tmp;

		for(j=0; j<10; j++)
			tmp.push_back( new MyObj(j) );
		
		layers.push_back(tmp);
	}
	return 0;
}

I need to serialize/deserialize the object "layers".

Can anyone give me an example on how to do this with boost serialization library?

Thanks in advance.
