+        This command is for managing gpg keys. It shows the public key
+        by default. There is no way to download or upload the private 
+        part of a key by design.
+
+        However you can create a new own key. You may want to consider
+        to sign the public key with your own existing key.
+
+        If a project has no key, the key from upper level project will
+        be used (eg. when dropping "KDE:KDE4:Community" key, the one from
+        "KDE:KDE4" will be used).
