package.use

The file {CONFIG_DIR}/package.use can be used to configure Use Flags for individual packages or package versions.

E.g.:

# This is a custom option
>category/foo-1.2.3-r1 flag -otherflag

Syntax

package.use should contain a list of package atoms, one per line, followed by flags. The atoms must specify the package category, but other components such as the version are optional. Flags prefixed with a - are considered disabled, otherwise they are considered enabled.

The file can also include comments, beginning with a #.
