使い方
By default, source files are located in the directory, while binary packages are located in the  directory. The locations for each can be changed by altering the DISTDIR and the PKGDIR variables respectively in. Both locations can grow quite big if not periodically cleaned; this is the reason was created.

Invocation
を実行すれば、全ての処理に関する概要と、オプションのリストと、使い方の説明が表示されます.

distfiles の削除

バイナリパッケージの削除
バイナリパッケージを含むディレクトリに対しては、代わりに、以下を実行:

より短くは、以下のコマンドでも同じです:

Options
By default, source files and binary packages corresponding to any ebuild in the current repository will not be deleted. This way, system administrators can easily downgrade a package or install a previously removed package, provided the package is still in the current repository tree.

As an example, suppose packages foo-1.0 and foo-1.1 are both in the repository. After updating from foo-1.0 to foo-1.1, run : source files for both versions will be kept, so if a problem occurs with foo-1.1 then the user can easily re-install foo-1.0 without re-downloading anything.

以前にアンインストールしたパッケージについても同様のことがいえます. （バージョンが何であれ） foo というパッケージがインストールされていたとします. このパッケージを（あやまって）アンインストールしてしまい、しかも も実行していても、foo のソースファイルが残っていれば、再ダウンロードすることなく再インストール可能ですね.

上記の例は、バイナリパッケージを処理する際にも当てはまります.

To save more disk space, add the  option: every source file or binary package that does not correspond to some currently installed package (version does matter) will be deleted. Please notice that this way users will not be protected in case they need to downgrade a package or re-install a previously removed package.

As an alternative, use both the  and the   options: every source file or binary package that does not correspond to some currently installed package (version does not matter) will be deleted. This still will not protect in case a re-install of a previously removed package is needed, but it will protect the sources if the package needs to be downgraded later.
