    Helper function for launching an external program as a "Door".

    the forcesize_func may be overridden if the sysop wants to use
    their own function for presenting the screen resize prompt.

    virtual node pools are per-door, based on the 'name' argument, up
    to a maximum determined by the 'nodes' argument.
    name='Netrunner' nodes=4 would mean that the door, Netrunner, has
    a virtual node pool with 4 possible nodes in it. When 4 people
    are already playing the game, additional users will be notified
    that there are no nodes available for play until one of them is
    released.

    for DOS doors, the [dosemu] section of default.ini is used for
    defaults::

        default.ini

        dropdir = /home/bbs/dos
        nodes = 4

    in 'opts', %%# becomes the virtual node number, %%c becomes the 'command'
    argument.

    'dropdir' is where dropfiles will be created if unspecified. you can
    give each door a dropdir for each node if you like, for ultimate
    compartmentalization -- just set the 'dropdir' argument when calling
    this function.

    -u virtual can be used to add a section to your dosemu.conf for
    virtualizing the com port (which allows you to use the same dosemu.conf
    locally by omitting '-u virtual')::
