-a, --active - show currently active useflags and their origin
-E, --enable - enable the given useflags
-D, --disable - disable the given useflags
+ -R, --remove - remove the use flag and restore the default
-P, --prune - remove all references to the given flags from
make.conf and package.use to revert to default
settings
- -p, --package - used with -E, -D, to apply to a specific
- package only
+ -p, --package - used with -E, -D, and -R to apply to a
