What does "keg-only" mean?

FAQ に記載がありました。

It means the formula is installed only into the Cellar; it is not linked
into /usr/local. This means most tools will not find it. We don’t do
this for stupid reasons. You can still link in the formula if you need
to with brew link.

kegとはビール樽という意味ですが、ここではインストールだけされていて/usr/localにはシンボリックリンクをつけてないパッケージのこと。…だそうです、コマンドではなくライブラリがこれにあたるようですね。
