// This header exists solely for portability.  Normally it just includes
// the native header <exception>.

// The header <exception> contains low-level functions that interact
// with a compiler's exception-handling mechanism.  It is assumed to
// be supplied with the compiler, rather than with the library, because
// it is inherently tied very closely to the compiler itself.

// On platforms where <exception> does not exist, this header defines
// an exception base class.  This is *not* a substitute for everything
// in <exception>, but it suffices to support a bare minimum of STL
// functionality.
