## Classes
class | G::Log
| A class for doing iostream-based logging. More...

## Namespaces

## Macros
#define | G_LOG_IMP(expr, severity) do { try { if(G::Log::at(severity)) G::Log((severity),__FILE__,__LINE__) << expr ; } catch(...) {} } while(0)
| The DEBUG macro is for debugging during development, the LOG macro generates informational logging in verbose mode only, the 'summary' LOG_S macro generates informational logging even when not verbose, and the WARNING and ERROR macros are used for error warning/error messages although in programs where logging can be disabled completely (see G::LogOutput) error conditions should be made visible by some other means (such as stderr).
