// Simple reference for using these macros and for writin components

//
// 1) use the WXDLLIMPEXP_MYCOMP in each class declaration:
//          class WXDLLIMPEXP_MYCOMP myCompClass {   [...]   };
//
// 2) use the WXDLLIMPEXP_MYCOMP in the declaration of each global function:
//          WXDLLIMPEXP_MYCOMP int myGlobalFunc();
//
// 3) use the WXDLLIMPEXP_DATA_MYCOMP() in the declaration of each global
//    variable:
//          WXDLLIMPEXP_DATA_MYCOMP(int) myGlobalIntVar;
