/**

*
* :Log: FileLog.java,v $
* Revision 1.5 2003/02/24 00:13:53 wurp
* Formatted all java code for cvs (strictSunConvention.xml)
*
* Revision 1.4 2001/06/20 04:05:42 wurp
* added log4j.
*
* Revision 1.3 2001/01/28 07:52:20 wurp
* Removed <dollar> from Id and Log in log comments.
* Added several new commands to AdminApp
* Unfortunately, several other changes that I have lost track of. Try diffing this
* version with the previous one.
*
* Revision 1.2 2000/12/16 22:07:33 wurp
* Added Id and Log to almost all of the files that didn't have it. It's
* possible that the script screwed something up. I did a commit and an update
* right before I ran the script, so if a file is screwed up you should be able
* to fix it by just going to the version before this one.
