[Seaside] Use of examples from Hasso-Plattner-Institut's tutorial

[Miguel Enrique Cobá Martínez]

In a previous mail Stephane Ducasse wanted to know the license of the 
code in the tutorial from Hasso-Plattner-Institut. Nobody replied with 
an official position.

In the About us section of the tutorial says that Michael Perscheid is 
the contact for feedback. Instead of writing a private mail to  him, I 
chose to send it to the list so it can be used as a public position 
regarding the use of the examples, techniques and information contained 
in the tutorial.

I refer only to the code and not to the text. As I understand it, if you 
buy a book about data structures in C, for example, you can use the 
techniques in it because it is meant to learn the language or the 
techniques. The same logic applies to the code and techniques you read 
in a forum on the web. The code in the forum's threads are for learning 
and is common to use the code verbatim or with little modifications in 
your own project. You get my point.

Can you, please, clarify this point?

Miguel Cobá
