Well, this part works fine (I found this syntax in the examples).

Yes, exactly.

Thanks for the link.

The files in the 'pymad' profile dir mainly contains magic commands we add
in the shell (these magic commands, combined with TPG - Toy Parser
Generator - gives us a set of dedicated commands to drive our
spectrometer).

But I just found that these magic commands are now registered using
decorators, and can even be defined from classes, which is nice. So, I
rewrote this part, and finally drop the profile dir.

Yes, it does!

BTW, where can one find the complete list of availables hooks names?

Thanks for your help, Matthias!
