+ USE Dependency Defaults + + In a 3-style use dependency, the flag name may immediately be followed by a + default specified by either (+) or (-). The former indicates that, when + applying the use dependency to a package that does not have the flag in + question in IUSE_REFERENCEABLE, the package manager shall behave as if the flag + were present and enabled; the latter, present and disabled. + + + Unless a 3-style default is specified, it is an error for a use dependency to + be applied to an ebuild which does not have the flag in question in + IUSE_REFERENCEABLE. + + + Note: By extension of the above, a default that could reference an ebuild using + an EAPI not supporting profile IUSE injections cannot rely upon any particular + behaviour for flags that would not have to be part of IUSE. + + + It is an error for an ebuild to use a conditional use dependency when that + ebuild does not have the flag in IUSE_EFFECTIVE. + +
