OK.  Did a little reading on this and gave it a test run.  It doesn't
generate quite what I was expecting.  This is a sample of what it generates.


kde-plasma/kde-cli-tools ~amd64
kde-plasma/kde-gtk-config ~amd64
kde-plasma/kdecoration ~amd64
kde-plasma/kdeplasma-addons ~amd64
kde-plasma/kgamma ~amd64
kde-plasma/khotkeys ~amd64
kde-plasma/kinfocenter ~amd64
kde-plasma/kmenuedit ~amd64
kde-plasma/kscreen ~amd64
kde-plasma/kscreenlocker ~amd64
kde-plasma/ksshaskpass ~amd64
kde-plasma/ksysguard ~amd64
kde-plasma/kwallet-pam ~amd64
kde-plasma/kwayland-integration ~amd64
kde-plasma/kwin ~amd64
kde-plasma/kwrited ~amd64
kde-plasma/libkscreen ~amd64


This is a example of what I currently have in my keyword file.

The output of what emerge gives includes a version.  The enalyze program
seems to leave that out which may lead to upgrades that I'm not looking
for yet. 

What I was hoping for, something that would for example see that
plasma-workspace-5.6.4 is either no longer installed or no longer
keyworded and can be removed from the file and then remove it. 
Honestly, I'm not a scripting guru but I sort of think it would be a
hard thing to do given that basically every line would have to be
checked.  Also, the commented part above it would be deleted to in a
ideal world.  That to would be difficult since not all lines have those
above it.

Hmmmm.  Gonna see what else it can do.
