다음의 메세지가 나옵니다. 어떻해야 하나요?
 Welcome to PHPDoc!
PHPDoc currently requires a late PHP4 version (4.0.3dev) to work. Some earlier version like to crash with memory trouble
. PHPDoc was programmed without using PHP4 features that means it will run with version prior to 4.0.3dev on fine day. B
ut again: my PHP3.0.15 crashed when it started to render the HTML documents :(.  I'll try to provide a solution as soon 
as possible.   --------------------------------------------------------------------------------
