comment in example files

[pir2]

Hi guys,
what are the weird comments in Qt examples files :
there are lines like that :
//! [0]
what is it ?

@pir2
Those are markups for the help system
I think it marks a section but i didnt look it up.
Feel free to delete them if u reuse a sample.

Well i sure will. I just felt like a step was missin in the generation of these files.. But np, it doesn't bother me at all, i was just curious (i was wonderin if it was not some markers for auto documentation, a little beat like javadoc). Whatever ty for your answer.
