Functions
int	main (int argc, char *argv[])
	Entry point for the g4system example program.

Detailed Description

This example demonstrates:

• registering g4system options via defineOptions()
• building a GEMC world (GWorld)
• building the Geant4 world (G4World)
• retrieving basic diagnostics (volume count and sensitive detector list)

The example intentionally keeps the logic minimal so it can be used as a template.

		char *	argv[] )

Parameters

argc	Number of command-line arguments.
argv	Command-line arguments passed to the global option system.

Returns

EXIT_SUCCESS on completion.

The program:

• creates a global GOptions instance configured with defineOptions()
• instantiates a GWorld using those options
• builds the Geant4 world via G4World
• prints basic diagnostics to the example logger
