This is the declaration of the Herwig.h header file.
This header file should be included in all Herwig++ classes.
At the moment, it is used mainly to define the macro HERWIG_NO_DEBUG
which switches off all the debugging information: see below
#define HERWIG_NO_DEBUG YES
(alternatively, one could define such macro by compiling with the flag:
g++ -c -DHERWIG_NO_DEBUG )
***LOOKHERE*** #define HERWIG_NO_DEBUG 1
Debugging in Herwig may be switched off completely by this compilation switched, eliminating possible overhead in error checking.
