Serialization of CObjects

I have a CObLists of CObjects called Leagues.  Each leage has a CObList of other CObjects called teams.  And each one of those objects has a CObList of CObjects called players.  How can I implement serialization so that the whole tree of cobjects is stored into a file?  Then how do I re-read that data back into memory?  Finally, I know I must used macros in the class declarations to specify that they can be serialized. How is this done?
  Thankyou.

class  Player : public CObject{
//stuff
};
class Team : public CObject{
//stuff
   CObList PLAYERS;
};
class  League : public CObject{
//stuff
   CObList TEAMS;
};
