+// Purpose:      MIPS32 Interrupt support
+// Description:  The macros defined here provide the HAL APIs for handling
+//               interrupts and the clock for variants of the MIPS32
+//               architecture.
+//              
+// Usage:
+//              #include <cyg/hal/var_intr.h>
+//              ...
