[DotGNU]special exception to GPL

[S11001001]

I have noticed that other projects, such as Classpath and Guile, list 
their GPL exceptions in every source file. Why is this not so for pnetlib?

Free software is a matter of the users' freedom to run, copy,
distribute, study, change and improve the software. More precisely, it
refers to four kinds of freedom, for the users of the software:

    * The freedom to run the program, for any purpose (freedom 0).
    * The freedom to study how the program works, and adapt it to your
    needs (freedom 1). Access to the source code is a precondition
    for this.
    * The freedom to redistribute copies so you can help your neighbor
    (freedom 2).
    * The freedom to improve the program, and release your
    improvements to the public, so that the whole community
    benefits. (freedom 3). Access to the source code is a
    precondition for this.
