dev-perl/B-Debug
Walk Perl syntax tree, printing debug info about ops
USE Flags
minimal
Global: Install a very minimal build (disables, for example, plugins, fonts, most drivers, non-critical features)
test
Global: Workaround to pull in packages needed to run with FEATURES=test. Portage-2.1.2 handles this internally, so don't set it in make.conf/package.use anymore
