//! @brief Defines an exception class inheriting from Standard_Failure.

//! This macro creates a complete exception class with:

//! Usage:
//! @code
//! DEFINE_STANDARD_EXCEPTION(Standard_OutOfRange, Standard_RangeError)
//! @endcode
//!
//! @param C1 Name of the exception class to define
//! @param C2 Name of the parent exception class (must be Standard_Failure or derived)
