+ AUTHOR: cy@FreeBSD.org
+ As of sysutils/screen-4.9.0_3, the multiuser feature is not supported
+ by default. The multiuser feature requires setuid root to function.
+ This creates a security risk. Some Linux distributions have had
+ non-setuuid root screen for a dozen or more years. FreeBSD is following
+ suit. A new MULTIUSER option has been added to enable users to install
+ setuid root screen. The MULTIUSER option default is OFF.
+ Users who wish to use the multiuser feature may,
+ - Build screen using the MULTIUSER option, or
+ - Poudriere users can use poudriere-options to enable the MULTIUSER
+ option, or
+ - Users can chmod the setuid bit for ${LOCALBASE}/bin/screen-4.9.0,
+ making screen setuid root to enable the multiuser feature.
