[OT] difference between Kleopatra and Kgpg, both from KDE

[Marco Möller <talby@debianlists.mobilxpress.net>]

Hello,
After I didn't receive an answer on the Debian user list, please allow 
me to also ask here:

Could someone explain for a raw beginner concerning the usage of PGP the 
difference between Kleopatra and Kgpg, what the typical work case is for 
the one and the other, what important feature the one and the other is 
missing which the other would have?

Thanks a lot, Marco.
