I've built a script called "autodepclean" that runs "--pretend --depclean"
and filters the output to a separate script file "cleanscript". You can
run "autodepclean" as a regular user, but "cleanscript" has to be run as
root. Here is how I use it...
1) Run autodepclean. It takes approximately 30 seconds on my machine.
2) Look at cleanscript with a text-editor, and delete lines that remove
programs you want to keep.
3) Run "cleanscript" as root. It automatically runs "revdep-rebuild" at
the end.
Note that "nano" is no longer a system requirement. If you want the
"nano" editor, you need to include it in world. I.e. "emerge nano".
The "autodepclean" script is attached to this post.
