What USE flags exist
There are two types of USE flags: global and local USE flags.
- A global USE flag is used by several packages, system-wide. This is what most people see as USE flags. A list of available global USE flags can be found on the main site or locally in the /usr/portage/profiles/use.desc file.
- A local USE flag is used by a single package to make package-specific decisions. A list of available local USE flags can be found on the main site or locally in the /usr/portage/profiles/use.local.desc file.
