A specification to specify specifications within specifications
Anyone who has worked in a project involving writing some software would have come across specifications of some kind - those holy documents written by the project elite that are a pain both to implement as well as to maintain and serve nothing more than as a hurdle to getting to a working product. Often spec documents either derive from another or many such documents build, by way of cross-reference, a connected specification which soon creates a need for another document to describe the relationship between these docs... which, of course, has to be kept up-to-date not only whenever any specification is updated but also when there are relationship updates or when new nodes come up etc. Soon anyone entering the project has to pass through this wall made of the interconnected web of specs only to understand soon enough that the product he/she is working on is quite different from what the specifications are dreaming about.
