One who develop games with Game Maker could use option 'Write error messages to game_error.log' and then use its content to fix errors. It is easy if this file is small. But what to do if this file is few megabytes? Here comes 'game_errors'. Being started from the same directory where game_error.log lies, program loads it, and dispay in convenient format, removing repetitive entries. Now all you have to do is to fix your errors. Too bad, program cannot do it.
