[gentoo-dev] [PATCH] eutils.eclass: Update function documentation.

[Ulrich Müller]

[-- Attachment #1: Type: text/plain, Size: 2001 bytes --]

Mention that einstalldocs() and in_iuse() are provided by the package
manager in EAPI 6.

in_iuse "must not" (rather than "should not") be used in global scope.
