如何制作Delphi的Debug Version? (100分)

FlashFXP的 Debug Version 做得很好，像：
1. Access violation at address xxxxxxx. Read of address xxxxxxxx
2. FileList index out of bounds [3]
3. Object class: TFont (像这一个还可以获得出错的class名字)
等等这样的错误发生时，不是像通常那样跳出一个对话框等着你按确定，而是直接将错误信息
放入到其目录下的"Debug.log"文件中，请问这是如何做到的？

附FlashFXP的Debug.log文件内容例子：

Application.OnException:=你设置的出错句柄。
然后使用宏定义
$DEFINE

$IFDEF
$ELSE
$ENDIF
就可以了，
然后在出错处理句柄函数里面判断。

出错信息可以得到，但是具体的Call Track就不知道了。

up

得到出错信息之后，写入文本文件之中。
