Hi,
thank you very much for help.
I was reading the manual about manifests, but still I don’t understand 
everything what I have to do.

I created now through your help a manifest with 6 packages,
but I got an error message:

Profil mit 6 Paketen wird erstellt …
guix package: Fehler/mistake: rename-file: Ist ein Verzeichnis/is a 
directory

and it didn’t create the directories in my "Musik" directory, but 
besides it, so I have home/gfp/Projekte/EmacsManifest
					Musescore
					Musik	
					Musik.new
					Musik-1-link	

  I wanted to put it in the "Musik" directory in order to have a good 
structure.

1.
Is it possible to change this?
..................................................................
I did a:
guix package -p /home/gfp/Projekte/Musik -m
/home/gfp/Projekte/Musik/musik.scm

2.
What would I have to do instead, in order to put it in my "Musik" directory?
(to know for the next time, to create an other profile)


Kind regards

Gottfried
