Re: fake out system

[Glenn Ericson <Glenn-Ericson@xxxxxxx>]

Seems to  me that you are adding   a bit more confusion to an already
problematical mission. What   is the   suggested  method to keep  these
temporary  fixes documented so they are  used   properly and considered  as
future development and changes  occur?

Sounds  like trouble?
