[gentoo-user] x11-bas/xorg-x11 removal

[ralfconn]

Rather than adding the whole x11-base/xorg-apps and x11-base/xorg-fonts, 
I'd like to build a list of the x11 utilities currently installed on my 
systems to add them to world in preparation of the xorg-x11 package removal.

Is anybody aware of some ready to use tool for the purpose, without 
re-inventing the wheel?

thanks,

raffaele
