/*
* Preliminary comments & code for CC feature in C-86.
*
* Comments and notes.
*
* o Numerous requests for this feature tend to make it valuable.
*
* o Suggest we have a field which may have multiple instances in any message.
*   This is the 'cc' field.  Suggest further that it be 2 * NAMESIZE bytes
*   long in order to allow node designators.
*
* o Implementation: The getMessage() function should build a linked list
*   (possibly generic list: libarch.c) as it reads in a message of each
*   CC recipient.  Will need to have a disposal function for this list as
*   each message is disposed of.  May take a little code massage to make
*   sure we hit all the high points.
*
* o Only available for Mail>.
* o (Since getMessage handles all the forms of getting messages from any
*   source, this handles all the net forms, too.)
*
* o Code massage points not otherwise covered in this file:
*   - Held Messages.
*   - Interrupted Messages(!).
*   - getMessage().
*   - putMessage() - how do we handle the analog to noteMessage()?  New
*     parameter?
*
* o Network provisions
*   - Net support not present for this type of message.
*   - New field, net only: Recipient override.  Indicates who mail is to be
*     given access to this message, may (easily) exclude recipient specified
*     in the mbto[] field.  New field named mboverride[NAMESIZE * 2].
*   - Like mbCC, should be handled as list with multiple instances.
*   - Check for mail should check this list instead of mbto iff mboverride
*     is present.
*   - mboverride fields will not contain node designators (initially).
*     mbCC fields will, where necessary.
*
* o Other comments and thoughts about design, etc.
*   - Unlogged users should not have access.
*   - List of CC users should be accessible to message writer.
*   - Able to remove someone from list of CC users???
*   - Net designation.  Use STadel's '@' convention?  Seems logical.
*   - NEED FORMAT FOR DISPLAY OF FINISHED & DELIVERED MESSAGE!
*   - NETHACK3.MAN will need updating.
*   -
