it's more civilized than many parts of the world like here in the states...

there is some but it's going to be difficult without externalizing the 
core elements in another set of files.

someone will need to approve the message as I'm not subscribe to -devel 
since I wasn't planning on being a developer.  ;-)
As I said to somebody else who has a copy, they are bloody raw hunks of
