 // This file contains helper macros used when exception support may be

 // disabled (as indicated by macro BOOST_NO_EXCEPTIONS).

 //

 // Before picking up these macros you may consider using RAII techniques

 // to deal with exceptions - their syntax can be always the same with 

 // or without exception support enabled.

 //

 /* Example of use:

 void foo() {

   BOOST_TRY {

     ...

   } BOOST_CATCH(const std::bad_alloc&) {

       ...

       BOOST_RETHROW

   } BOOST_CATCH(const std::exception& e) {

       ...

   }

   BOOST_CATCH_END

 }

 With exception support enabled it will expand into:

 void foo() {

   { try {

     ...

   } catch (const std::bad_alloc&) {

       ...

       throw;

   } catch (const std::exception& e) {

       ...

   }

   }

 }

 With exception support disabled it will expand into:

 void foo() {

   { if(true) {

     ...

   } else if (false) {

       ...

   } else if (false)  {

       ...

   }

   }

 }
