Okay, so I tried to build all binary packages from one source package. Not sure if it's the good way.
It builds those binary packages: awf-gtk2 - A widget factory is a theme preview application for GTK awf-gtk3 - A widget factory is a theme preview application for GTK awf-gtk4 - A widget factory is a theme preview application for GTK To access further information about this package, please visit the following URL: https://mentors.debian.net/package/awf-gtk/ Alternatively, one can download the package with dget using this command: dget -x https://mentors.debian.net/debian/pool/main/a/awf-gtk/awf-gtk_2.5.0-1.dsc
