║ GT-HELP ║ GTDDIR.BBS - the Doors access levels
╚═════════╩════════════════════════════════════════════════════════════

    Doors permit callers to run external programs.

    The GTDDIR.BBS file assigns an access levels to each DOOR.  It may
    optionally specify a single question which is asked when each door is
    opened.

    Example :

       ┌──────────────────────────────────── ─ ─ ─
       │E [#1_dbase_eq]
       │=D [#2_dbase_patch]
       │E [#3_msgmate] Please choose <Z>IP or <A>RC format
       │Z [#4_password]
       │Z [#5_todays_users]
       |

    Doors must be numbered sequentially, starting with 1.  This file must
    contain one line per door, with no comments, such that the permission
    for DOOR n will be found on the nth line.

    In more detail :

    ┌────────────────────────────────────────────────────── Access Level
    │       ┌────────────────────────────────────────────── Reference info
    │ ┌─────┴────┐                   ┌───────────────────── Question to Ask
    │ │          │ ┌─────────────────┴─────────────────
    E [#8_filebox] Please choose <Z>IP or <A>RC format


┌──────────────┐
│ Access Level │
└──────────────┘

    The ACCESS LEVEL is a normally single character, indicating the minimum
    callers access level to obtain access to this door.  It can optionally
    be preceded by = to indicate that only callers at this exact level may
    access this door.


┌────────────────┐
│ Reference Info │
└────────────────┘

    The REFERENCE INFO is plain text enclosed in [] brackets with no
    embedded spaces.  It is useful to mention the door number and name
    here, though it serves no useful purpose other than to remind the sysop
    of the door allocation when updating the file.


┌─────────────────┐
│ Question to Ask │
└─────────────────┘

    The QUESTION is optional.  Any text after the ] will be displayed
    whenever a caller opens that door.  The caller will then be expected to
    answer the question (the answer will be passed as a parameter to the
    door batch file).
