security/x11appjail: New port: Tool for creating, verifying, installing, and running AppJails
x11appjail is a specialized tool for creating, verifying, installing,
and running AppJails. An AppJail is a CLI, TUI or X11 application
that runs inside a FreeBSD jail but is perceived by the end user
as identical (or at least very similar) to an application running
directly on the host system.
This tool makes extensive use of appjail(1) as its engine; however,
unlike the latter, the primary user in x11appjail is neither root
nor a privileged user, but rather an unprivileged user. The fundamental
goal of this project is to grant the user limited access to the
jail, restricted solely to the execution of a CLI, TUI or X11
application.
