1. There is no %RDIFF%-like Wiki syntax to invoke this script.
2. This script is considered a FatCgiScript because the code to implement the diffing functionality is directly in the script rather than being a backend library. Fixing this would minimally require all subs except main to go into a DotPm? file.
   • This is not broken as there is no requirement to fix it. I would look to factor out the functionality if it needed to be accessed from elsewhere. This script is 257 lines long, is that really fat? [ JohnTalintyre 02 Jul 2002 ]
     • I agree that TWikiMission does not say that scripts cannot be fat, therefore I agree it is not broken. (Else I'd have logged it as a bug ) Whether the script is 3 lines, 257 lines or 1,000,000 lines doesn't determine fatness, the only thing that does is that functionality is in the front end script.
