Hi Csepp,

this was anyhow my question.

Until now I installed everything in my main profile

1.  I don't know yet how to create a profile/manifest.

I was reading the cookbook and the manual already several times about 
that, but it seems to me difficult.

2.  If I create an other profile through a manifest
what is the benefit of it in my case?


3.  I would have to put all my 60 packages there (how?) and if I 
download an other package, would I have to create the manifest again and 
again?

4.  And if I want to update the packages, lets say every second week, 
then I would have to create the manifest again every second week.

5.  Would I then have to uninstall all my installed packages in the main 
profile, in order not to have it twice?

6.  How could I then use my manifest? Which commands would I have to use 
to open it and to use my packages?


Kind regards

Gottfried
