Thanks Stefan, I was wondering about something along those lines, but...
Inside master-pdf-editor-4.3.89_qt5.x86_64.deb I find:
data.tar.xz > /./opt/master-pdf-editor-4/masterpdfeditor4
              /./usr/share/icons/hicolor/128x128/apps/masterpdfeditor4.png
              /./usr/share/applications/masterpdfeditor4.desktop

And, inside master-pdf-editor-5.7.08-qt5_included.x86_64.deb I find:
data.tar.xz > /./opt/master-pdf-editor-5/masterpdfeditor5.sh
              /./opt/master-pdf-editor-5/masterpdfeditor5.png
              /./opt/master-pdf-editor-5/masterpdfeditor5
              /./usr/share/applications/masterpdfeditor5.desktop
              /./usr/share/icons/hicolor/256x256/apps/masterpdfeditor5.png

So, everything looks fairly well distinguished - but, I know *nothing*
about packaging...

Thanks
