We are advised that there is a problem with this. If a software manufacturer advises you that their software is complaint, but it isn't, you can sue them. But if you act on someone else's interpretation of what that manufacturer says, you will find it much more difficult to obtain recourse in law. Millennium Bug Toolkit tells you exactly what the manufacturer says and where they said it. Some claim to scan the whole of your hard drive to check whether all of your data is complaint.
Programmers are well known for their inventiveness.
Applying wildly undescriptive names to variables is very common. We therefore conclude that such scanning devices may be useful as tools for highly trained programmers to help reduce their searching time. However, if such a tool were used by unskilled personnel and considered to be complete, we would be very nervous about the potential consequences.
