+<h3>Error options</h3>
+
+Here you can set a number of options that relate to the way errors are reported.
+
+<p>
+<b>Display error messages</b><br>
+When checked, error messages are shown to the player. In the final 
+version of the game you might want to uncheck this option.
+
+<p>
+<b>Write error messages to file <tt>game_errors.log</tt></b><br>
+When checked all error messages are written to a file called 
+<tt>game_errors.log</tt> in the game folder.
+
+<p>
+<b>Abort on all error messages</b><br>
+Normally, certain errors are fatal while others can be ignored. 
+When checking this option all errors are considered fatal and lead 
+to aborting the game. In the final version of the game you distribute 
+you might want to check this option.
+
+<p>
+<b>Treat uninitialized variables as 0</b><br>
+One common error is to use a variable before a value is assigned to it. 
+Sometimes this is difficult to avoid. When checking this option such 
+uninitialized variables no longer report an error but are treated as 
+value 0. Be careful though. It might mean that you don't spot typing 
+mistakes anymore.
