Re: [gentoo-portage-dev] Undo feature in portage-ng ?

["Nicolás Echániz" <nico@rakar.com>]

# emerge unmerge thissocoolapplication
does not unmerge the dependencies that were installed along with the 
application, does it?

What I usually do is look into /var/log/emerge.log to see what 
dependencies were installed when I installed thissocoolapplication and 
unmerge them all. This could be done automatically, but would only be 
approppriate if you were unmerging something you just emerged. 
Otherwise, you could unmerge a library that is a dependency to some 
other package that was installed later.
