577<p>
578When you uninstall software Portage will not automatically unmerge the
579dependencies that aren't needed anymore. If you want to "clean" your system from
580those orphaned dependencies, you can use <c>emerge depclean</c>. This will
581search for all installed software that you haven't installed explicitly and that
582isn't a dependency of software that you have installed explicitly.
583</p>
584
585<warn>
586Using depclean can seriously impair your system. Use with caution and
587double-check the list of dependencies that Portage wants to remove before you go
588ahead!
