  Doors
  -----
    Doors is a means by which you may run outside programs through
    ^variantname.  Control of the computer is actually handed over
    to the external program, and when it is finished, control is
    returned to ^variantname.

    Doors may be activated by the use of the <D> or <.D> command.
    Typing <D> will cause ^nodetitle to list all the doors available
    and then prompt for the entry code of the desired door.  The
    display format is:

   <entrycode>     :  <description>
   <entrycode>     :  <description>
   <entrycode>     :  <description>

    Alternatively, you may type '.D entrycode' to bypass the list and
    immediately enter the appropriate door.

    After a slight delay, the external program will be brought online.
    Some doors may spew out a few garbage characters before coming up;
    don't worry unless you lose carrier.

    When you exit the door program, control will be returned back to
    ^nodetitle.

    Here is a list of currently available doors on ^nodetitle.
