Update marketing-perl

Not all supermarkets in The Netherlands have cash registers that run on Linux and Perl.  Just the one big chain (and it is a really big chain, already having supermarkets in Germany and Belgium too).

The traffic information system that is located along the Dutch highways is quite recognisable and the system has many "poles" along the highways.  But they certainly do not run the highways, that is done by the government organisation "Rijkswaterstaat", part of the Dutch ministry for Ingrastructure.  The privately owned organisation for this specific traffic information system supplies their information to radio, tv, newspapers, websites and in some way also to "Rijkswaterstaat".  This information, together with several other sources that Rijkswaterstaat has (like many Rijkswaterstaat-owned cameras along / over the highways), is used to determine how to run the highways.  I will change the wording of my next installment of this talk to correctly explain this.
