First of all I just would like to rephrase my comment in the patch.

It was not meant to be a suggestion for Ingo to write more documentation
per se, it was my way of pointing out that such "documentation" is 
useful for beginners and that I, as Valdis, appreciated reading it.
So it was more of a "keep coming" and don't rephrain from writing these
examples in the e-mails kind of thing.

Now about the wiki. Yeah, that sounds great and I didn't know about it
yesterday. It will be nice if the wiki becomes a place where people
can look for such usage examples.

Thanks for the attention,
Carlos
