Functions
std::unique_ptr< QCoreApplication >	gemc::makeQtApplication (int &argc, char *argv[], bool gui)
	Create a Qt application instance suitable for GUI or batch execution.
int	gemc::get_nthreads (const std::shared_ptr< GOptions > &gopts, const std::shared_ptr< GLogger > &log)
	Determine the number of worker threads to use for the run.
std::vector< std::string >	gemc::verbosity_commands (const std::shared_ptr< GOptions > &gopts, const std::shared_ptr< GLogger > &log)
	Build a list of Geant4 UI commands that reduce verbosity across subsystems.
std::vector< std::string >	gemc::initial_commands (const std::shared_ptr< GOptions > &gopts, const std::shared_ptr< GLogger > &log)
	Build a list of Geant4 UI commands needed at startup.
void	gemc::run_manager_commands (const std::shared_ptr< GOptions > &gopts, const std::shared_ptr< GLogger > &log, const std::vector< std::string > &commands)
	Execute a sequence of Geant4 UI commands through the UI manager.
void	gemc::start_random_engine (const std::shared_ptr< GOptions > &gopts, const std::shared_ptr< GLogger > &log)
	Select and start the random engine, then seed it.

Detailed Description

This header contains small, self-contained utilities used during GEMC startup:

• Qt application instantiation for GUI and batch modes
• Computation of the number of threads to use
• Preparation of Geant4 UI command sequences
• Execution of those commands through the UI manager
• Random engine selection and seeding
