Q applets/ja

QアプレットはCで書かれた小さくて素早い、portageのヘルパーツールです. このガイドは、 パッケージで提供されているこれらヘルパーツールの基本的な使い方を説明します.

The package is a collection of very fast utilities written in C, which are meant to offer a faster but more limited alternative to their  counterparts. Please note that q applets are not meant to replace gentoolkit. The utilities may be much more efficient than the equivalent ones from gentoolkit and might be better suited to be used in scripts that need to call Portage repeatedly, but they do not offer the same functionality. q applets do not consider eclasses and do not provide tools like or.
