qpkg -I will list them, as will ls /var/db/pkg.

"equery depends package" shows dependencies.

The safest approach is to remove from /var/lib/portage/world any programs
you do not want. Then run

emerge -uadVN world
emerge -p depclean
# check output of above
emerge depclean
revdep-rebuild -p
revdep-rebuild

Because many topics are too general for that.You question could apply to
servers, desktop, amd64, ppc et al. A catch all group is necessary.
Splitting a list generally results in more posts, since the same threads
end up on more than one list.
