mktuntap
--------

Creates a TUN or TAP device on a specified file descriptor, sets an
environment variable indicating its name, and then execs into the rest
of argv.

Unlike programs like tunctl, since mktuntap execs into the next
program with the created device available on a file descriptor, the
devices it creates don't need to have the IFF_PERSIST flag set, and
will therefore automatically be destroyed by the kernel when the file
descriptor is closed.  It works very well with, but is in no way
coupled to, the execline scripting language.
