[Composer] Create Metapackage?

[Mikael Löfgren]

Hi!
I just bought Composer 7, i have used Iceberg to create package before
and was trying Composer out.

So my two first questions is, is there a way to create Metapackage in  
Composer 7?

And in Iceberg my .pkg files had info string in Finder where i could  
se which version my .pkg has.
But cant find that either in Composer.

In Iceberg i set the info here:
Iceberg->Display Information->Get Info String

best regards
Mikael
